摘要: 在全面推进长江三角洲一体化发展的关键时期,进行长江三角洲地区资源环境承载力评价,可为地区资源环境和经济社会协调发展提供资源配置和空间优化的基本依据。在系统了解长江三角洲地区资源储备、生态环境和社会发展状况的前提下,分别从社会经济、生态环境和水土资源3个层面选择17个评价指标,完成资源环境承载力评价指标体系的构建。基于GIS技术,采用层次分析法和专家打分法得到各个指标的权重,通过线性加权求和法确立空间尺度的承载力评价模型,对长江三角洲地区资源环境承载力进行估算、等级划分及空间特征分析。结果表明,2015年长江三角洲地区资源环境承载力在中东部的长三角城市群区域以较低、低等级为主,北部区域承载力以高等级为主,南部区域以较高、中等等级为主;受地形条件影响,平原农业区承载力高,山地、丘陵地区承载力以较高、中等为主。长江三角洲地区资源环境承载能力状况不容乐观,区域内资源、环境差异较大,部分地区资源环境承载力仍面临较大压力。加大生态环境保护和建设力度十分重要,以提高资源环境承载力水平。

Abstract: In the critical period of comprehensively promoting the integrated development of Yangtze River Delta,the evaluation of the carrying capacity of resources and environment in the Yangtze River Delta can provide the basic basis for resource allocation and spatial optimization for the coordinated development of regional resources, environment and economy. Based on a comprehensive understanding of the resource reserve, ecological environment and social development in the Yangtze River Delta region, 17 evaluation indexes were selected from the three levels of social economy, ecological environment and water and soil resources respectively to complete the construction of the evaluation index system of resource and environment carrying capacity. Based on GIS technology, AHP and expert scoring method were used to get the weight of each index and the linear weighting method was adopted with the method of sum, the evaluation model of resources and environment carrying capacity based on spatial scale was established, and the resource and environment carrying capacity of Yangtze River Delta was estimated, classified and analyzed. The results showed that the resources and environment carrying capacity of the Yangtze River Delta region in the middle and east of the Yangtze River Delta urban agglomeration was mainly low and low grade in 2015, the northern region was mainly high-grade, and the southern region was mainly high and medium grade; Affected by the terrain conditions, the value of plain agricultural area was high, and that of mountainous and hilly areas was mainly high and medium. The carrying capacity of resources and environment in the Yangtze River Delta was not optimistic. There were great differences in resources and environment in the region, and some areas were still facing greater pressure. It was very important to strengthen the protection and construction of ecological environment to improve the carrying capacity of resources and environment.

Key words: Yangtze River Delta, evaluation index, resource and environment carrying capacity, remote sensing and GIS
