Abstract

Abstract: 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.

Key words: food security, agricultural planting structure, spatial-temporal analysis, county level, Jiangsu Province
