Taking four varieties of rapeseed Zhongyouza 39, Zhongshuang 11, Huayouza 62 and Huayouza 9 as test material, spraying water was used as a control, and the effects of spraying paclobutrazol on agronomic characteristics,disease resistance,yield and quality at two stages（the closing of crop and the start of flower bud） were studied. The results showed that paclobutrazol treatment significantly decreased stem height, effective branch site, and the number of invalid branches and increased the number of effective siliques on branches and per plant, and it had little impact on other indicators at the closing of crop stage; beyond that paclobutrazol treatment significantly enhanced disease resistance and increased the yield and oleaginousness at two stages. However, the content of erucic acid and glucosinolate in rapeseed were significantly decreased at the closing of crop stage, and the performance was consistent between different varieties of rapeseed. This study showed that the paclobutrazol treatment decreased stem height, increased yield and improved quality in rapeseed at 150 mg/L concentration conditions at the closing of crop stage.

In order to study the impact of climate change on local cultivated land use patterns in central Yunnan Plateau,the regional irrigation water demand index of cultivated land use was constructed to quantitatively express the change characteristics of regional cultivated land planting structure and the response of regional cultivated land use structure to climate change. The results showed that the climate in the study area had a significant warming and drying trend, with an average warming rate of 0.35 ℃/10 a, an average precipitation decreasing rate of 79.15 mm/10 a, and an average decreasing rate of Kira dry-humidity index of 0.65/10 a from 1998 to 2019. At the same time, the regional cultivated land use structure showed a continuous trend of “drought”, and the proportion of crops with relatively small irrigation water requirements increased significantly, while the proportion of crops with relatively large irrigation water requirements decreased rapidly. Under the background of continuous increase of sown area, the index of irrigation water requirement of regional cultivated land utilization decreased continuously. The sown area of main crops and irrigation water demand index of regional cultivated land use were significantly correlated with mean annual temperatures, precipitation and Kira's humidity/aridity index. The response of regional cultivated land use structure to climate warming and drying was “drought”, and this response had a lag.

The ecosystem service values and their changes in Fuzhou City, Jiangxi Province were studied based on the change of land use status data in 2010 and the change of the third land survey data in 2020. The results showed that, from 2010 to 2020, Fuzhou City had the largest area increase and single dynamic degree of water and construction land, the relatively larger reduction range of unused land, grassland and wetland, and the largest decrease of arable land area; the main direction of land transfer was the conversion of grassland and arable land to forest land, and the conversion of arable land and forest land to construction land. From 2010 to 2020, ecosystem service values in Fuzhou City showed an upward trend, the net increase was RMB 13.668 billion yuan, and the increase mainly came from the increase of the area of water and forest land. The spatial distribution of the value-added and value-impaired areas of ecosystem service value was uneven. Therefore, the construction of compensation mechanism for ecological environment construction should be strengthened to promote the balanced and coordinated development of ecological environment and sustainable economic development in Fuzhou City in the future.

The greenhouse gas emissions from agricultural sources in Xinjiang from 2009 to 2019 were estimated with reference to the methods recommended in the Provincial Greenhouse Gas Guidelines. The temporal characteristics and spatial differences of greenhouse gas emissions from agricultural sources in Xinjiang were explored. The decoupling characteristics and influencing factors of greenhouse gas emissions from agricultural sources in Xinjiang were analyzed using Tapio model and LMDI decomposition method. Finally, the emissions of greenhouse gas from agricultural sources in Xinjiang in 2030 and 2050 were predicted by constructing different scenarios. The results indicated that the emission of greenhouse gases from agricultural sources in Xinjiang showed an overall upward trend from 2009 to 2014, which was divided into two stages： fluctuating rise and steady rise, taking 2013 to 2014 as the boundary; The regional emissions of greenhouse gases from agricultural sources in Xinjiang were significantly different, and the Ili Kazakh Autonomous Prefecture and Altay region belonged to the “double high” region; the decoupling state of agricultural greenhouse gases in Xinjiang was not ideal, mainly weak decoupling; the most important factor to curb agricultural greenhouse gas emissions in Xinjiang was agricultural production efficiency, followed by agricultural structure. The most important factor to promote agricultural greenhouse gas emissions was agricultural economic level, followed by agricultural population size; the prediction results showed that the agricultural greenhouse gas emissions in Xinjiang would not reach the peak in 2030 and 2050, and would continue to rise. Facing the severe emission reduction situation in Xinjiang, agricultural production efficiency should be improved the industrial structure should be adjusted and optimized emission reduction indicators should be quantified, and emission reduction tasks should be implemented.

The relationship between land use/landscape pattern and water quality at different spatial and temporal scales was explored to provide reference for rational planning of land resources, so as to protect the water quality safety of the watershed. Based on the data of river water quality and land use in Shenzhen River-Bay Watershed in 2020, the sub-basin scale and 8 buffer zone scales of riparian zone were selected, and Spearman correlation analysis, stepwise regression analysis and redundancy analysis were used to quantitatively explore the impact of land use/landscape pattern on river water quality in the rainy season and non-rainy season. The results showed that the water quality of Shenzhen River-Bay Watershed during the non-rainy season was better than that during rainy season, and the water pollution was more serious in the lower reaches and the outlet of the river. Construction land and forest land were the main landscape types at different spatial scales, and the proportion of construction area and forest area, patch density（PD）, edge density（ED）, mean euclidean nearest neighbor distance（ENN_MN）, CONTAG and aggregation index（AI） were significantly correlated with water quality change. At the scale of 300 m riparian buffer zone in the rainy season, landscape indexes had the most significant impact on water quality, and forest land was the main significant explanatory variable. The water quality of Shenzhen River-Bay Watershed had significant temporal and spatial differencs. In addition to the increase of forest area ratio could improve the water quality, the increase of construction area ratio, ED and PD value would lead to the decrease of water quality. The optimization of landscape pattern within 300 m riparian buffer zone should be emphasized when improving water quality in the basin.

Based on the agricultural statistical data from 1990 to 2019, the temporal and spatial distribution and “non grain-oriented” situation of crop planting structure in Jiangsu Province in the past 30 years was discussed by using the methods of spatial data analysis and mathematical statistical analysis. The results showed that the planting area of crops in Jiangsu Province had been declining in recent 30 years, and the proportion of the total sown area of cash crops in the total area of crops in Jiangsu Province showed a rapid reduction trend. The sown area of grain crops in northern Jiangsu Province maintained a gradual growth trend, and the“non grain-oriented” trend in southern Jiangsu Province was obvious. Wheat had gradually replaced rice as the food crop with the widest sowing area in Jiangsu Province. Rice planting in southern Jiangsu Province has shifted to central and northern Jiangsu Province in recent 10 years. Corn was the most widely planted in Nantong City, and the sowing level of soybean in the whole province continued to be low. The planting types in Jiangsu were gradually diversified, and a combination of many kinds of crops had been formed. The food security situation had changed for the better.

A randomized block design was carried out to study the effects of high-carbon biochar-based fertilizer with different microbial agents on soil fertility and tobacco yield and quality. The results showed that the high-carbon biochar-based fertilizer combined with Bacillus amyloliquefaciens or Trichoderma viride could increase the number of soil bacteria and fungi, and the plant height, stem circumference, maximum leaf area, dry matter accumulation, yield, output value of tobacco and the proportion of medium and high grade tobacco compared with the conventional fertilization control（T1）. Among them, conventional fertilization+high-carbon biochar-based fertilizer+Bacillus amylolyticus+Trichoderma viride（T5） treatment had the best effect on improving the yield and quality of tobacco leaves, and the yield, output value of tobacco and the proportion of medium and high grade tobacco increased by 25.96%, 35.69% and 12.13% respectively compared with T1 treatment. Compared with T1, T5 treatment could also increase soil water content, organic matter content, ammonium nitrogen content, available sulfur content and soil microbial biomass carbon, nitrogen and phosphorus content. Therefore, high-carbon biochar-based fertilizer combined with Bacillus amyloliquefaciens and Trichoderma viride could effectively improve the biological characteristics of tobacco soil and enhance the yield and quality of tobacco leaves.

In view of the damage assessment and prevention needs of agricultural pests and diseases in Shandong Province, the risk assessment and zoning of corn borer disasters in Shandong Province in recent years were conducted. The technical specification with the agricultural industry standard of the People's Republic of China Technical Specitication for Corn Borer Detection and Reporting （NY/T 1611—2008） and the local standard for grading the occurrence degree of corn borer from Shandong Plant Protection Station were combined. Based on the statistics and data extraction of the occurrence of corn borer in Shandong Province in the past 13 years, the classification criteria of the occurrence degree of corn borer were put forward, which took the rate of damaged plants as the main dividing factor and the number of pests on 100 plants as the auxiliary factor. The classification and frequency statistics of the occurrence degree of corn borer were carried out in 16 prefectural cities in Shandong Province; based on the index system, which took the occurrence frequency of corn borer as the disaster factor, the maize sown area and meteorological conditions as the disaster environment factor, and the maize yield as the carrier factor, the risk regionalization of single index factor was constructed. The comprehensive risk index was calculated through the normalization process, and the comprehensive risk regionalization of corn borer in Shandong Province was generated according to the comprehensive risk index. The results showed that the risk of corn borer in Shandong Province mainly occurred in the central and western parts of the province, among which, Heze City was a high-risk area, and Dezhou City, Weifang City, Binzhou City and Liaocheng City were higher-risk areas.

In order to clarify the changes of soil and crop indexes under different fertilizer reduction and efficiency enhancement modes, field plot experiments were conducted to study the effects of different fertilizer reduction measures on the yield, quality and soil physical and chemical properties of Chinese cabbage. The results showed that among the different fertilizer reduction measures, the yield of pakchoi recommended for fertilization was the highest, which was 31 945 kg/hm². Under the fertilizer reduction and efficiency increase measures, the yield of pakchoi increased by 30.85%~43.26%, the content of nitrate in leaves decreased by 16.54%~28.33%, the content of soluble protein increased by 4.96%~11.83%, and the content of VC and soluble sugar did not change significantly. The quality of Chinese cabbage was the best by applying organic fertilizer instead of chemical fertilizer. After fertilizer reduction, the nitrogen accumulation of Chinese cabbage increased by 13.20%~25.70%, and there was no significant difference in phosphorus and potassium accumulation. The agronomic utilization rate of water-soluble fertilizer was 95.39 kg/kg, which was significantly higher than that of other treatments. The agronomic efficiency of farmers' habitual fertilization was the lowest, only 24.23 kg/kg. Fertilization could improve soil physical and chemical properties, but the planting of one season Chinese cabbage had no significant effect on soil pH and EC value. After the application of organic fertilizer, the contents of organic matter, mineral nitrogen, available phosphorus and available potassium in the soil were also significantly higher than those of other fertilization treatments. In conclusion, considering the yield and quality of Chinese cabbage, fertilizer agronomic efficiency and soil fertility, applying organic fertilizer and water-soluble fertilizer could achieve better results.

The results showed that the daily net carbon sequestration per unit leaf area of 28 tree species was 4.00~16.49 g/（m²∙d）. The daily net carbon sequestrations of Zelkova serrata, Nerium oleander and Cotinus coggygria var. cinerea were high. Nerium oleander, Quercus variabilis and Pterocarya stenoptera were strongly positive species. While Cinnamomum camphora, Triadica sebifera, Zelkova serrata etc. 9 species belonged to positive tree species. Catalpa bungei, Camptotheca acuminate, Sapindus saponaria etc. 12 species belonged to neutral tree species, while Camellia oleifera, Elaeocarpus decipiens, Castanopsis tibetana and Emmenopterys henryi belonged to shade-tolerant tree species. Pterocarya stenoptera, Triadica sebifera, Zelkova serrata, Toona ciliate, Catalpa bungei, Camptotheca acuminate and Quercus variabilis with high carbon sequestration capacity and strong adaptability could be preferentially used for carbon sink afforestation in Hubei Province and even the middle and lower reaches of the Yangtze River. In the construction of carbon sequestration efficient carbon sink forest, the reasonable collocation of strong positive trees and shade-tolerant shrubs should be considered.

To investigate the effect of shikonin （SHI） on rheumatoid arthritis （RA）, ICR mice were randomly divided into 4 groups, including the normal group and three experimental groups （model group, positive drug group and SHI group）. After 15 days of modeling, the drug treatment losted for 60 days. The positive drug group was given meloxicam 50 mg/（kg·d）, the SHI group was given shikonin 2 mg/（kg·d）, and the normal group and model group were given normal saline. The right ankle joint of the mice was separated, and the degree of synovial inflammation （grade 0-3）, cartilage destruction （grade 0-4） and bone infiltration were evaluated. The thymus and spleen of mice were separated and thymus index and spleen index were calculated. Histopathological evaluation and some serum biochemical indexes （including inflammatory factors and antioxidant factors） were analyzed and determined. The results showed that shikonin could significantly improve the symptoms of joint redness in mice. The levels of nitric oxide （NO）,tumor factor α （TNF-α）,interleukin 1β （IL-1β） and interleukin 6 （IL-6）,in the SHI group were significantly lower than those in the AA model group, the level of malondialdehyde （MDA） in serum as significantly lower than that in the AA model group, and the enzyme activity of superoxide dismutase （SOD） was significantly higher than that in the AA model group.

Eco-agriculture is an important approach to achieve sustainable development. In any country, agriculture is considered the most critical sector concerning socioeconomic development. However, the traditional agriculture supply chain severely suffers from many shortcomings, such as fraud, corruption, and information falsification. The emerging blockchain technology involving a distributed database system with multiple independent nodes exhibits many advantages, including data security and transparent traceability systems, resulting in a recent shift in the traditional agriculture model with increasing blockchain technology development. The sustainable eco-agriculture supply chain offers a key avenue for the agriculture industry to conceptualize sustainable economic activities with a concern for environmental sustainability and societal well-being. To advance the application of such technology in agriculture, either practically or theoretically, the present study conducted a PEST （political, economic, social, and technological） analysis concerning blockchain technology application in different processes from the perspective of sustainable agriculture supply management. Through this analysis, combined with three agricultural blockchain cases, blockchain-enabled eco-agriculture revealed a great development potential in China. Simultaneously, certain obstacles and challenges remained and needed to be addressed by the government （either central or local）, enterprises and individuals.

On the basis of using the DEA-Malmquist index method to measure agricultural total factor productivity, this paper selected the panel data of 31 provinces （municipalities and autonomous regions） from 2004 to 2020, and used the fixed effect model and the threshold effect model to test the impact of financial agricultural subsidies on agricultural total factor productivity. The results showed that there was an inverted “U” type relationship between financial agriculture and agricultural total factor productivity, which was still established after changing the measurement method, replacing explanatory variables and considering endogenous problems. When the data was divided into three regions, the study found that the inflection point came the earliest in the eastern region and the latest in the western region. The increase of investment in agricultural science and technology would delay the arrival of the inflection point between financial agriculture and agricultural total factor productivity and improve the use efficiency of financial support for agriculture.

At the current stage of high-quality economic development, enterprises were required to take more responsibilities in environmental, social, corporate governance and other aspects. The connotation of enterprise value was gradually diversified. It was especially true for agricultural enterprises, which relied closely on the natural environment to achieve their own development and shoulder many important social responsibilities such as ensuring food security and increasing the income of farmers. Based on the existing enterprise value evaluation theories and methods, the existing research results of non-agricultural enterprise and agricultural enterprise value evaluation were combed from the perspective of economics, economics and sociology, and the future development direction of agricultural enterprise value evaluation was explored. It was believed that further research should be carried out in the future in three aspects： The diversified understanding of enterprise value, the exploration and improvement of evaluation methods, and strengthening the monetization evaluation of agricultural enterprise value.

As an important tool to explain spatial phenomena, space production theory breaks through the conventional thinking of space from the perspective of traditional geography and reveals the sociality of space. Under the influence of urbanization and industrialization, rural space is constantly produced and reconstructed, which also needs to be endowed with social thinking. From the perspective of space production theory, this paper focused on the rural areas of a central province, constructed a three-dimensional analysis framework composed of material space, cultural space and social space, and aimed to reveal the characteristics of rural space from materialization to social conceptualization. It was found that the rural material space had an obvious interest tendency, the cultural space was homogenized between urban and rural areas, and the social space had obvious conflicts between the government and the people. Based on the characteristics of rural space transformation, three aspects of countermeasures of setting up the concept of space sharing, protecting the unique culture of space and developing space consultation and governance were put forward, in order to enrich the dimensions of rural construction and development, and provide reference for the new rural construction and the promotion of rural revitalization strategy.

From a spatial perspective and combined with field investigations, it was found that the Y community in K City was faced with governance dilemmas such as the rupture of residents' social networks, insufficient psychological adaptation, and conflicting living habits. Based on this, it was proposed that the spatial reconstruction strategy was a powerful governance practice to deal with contradictions and conflicts under spatial evolution. The interaction of spaces, diverse participation and cultural links were important action logics to achieve community harmony, good governance and co-governance. Community committees could use the expansion of physical, psychological and cultural space to strengthens the identity of residents.
