基尼系数视野下的安徽省水土资源匹配分析

为科学地规划区域农业的发展,通过构建区域基尼曲线和计算区域基尼系数,同时选用单位面积耕地所拥有的水资源总量法,对安徽省2000—2012年的水资源和耕地资源进行匹配分析。结果显示:安徽省多年平均水土资源空间匹配的区域基尼系数G=0.4449,水土资源空间匹配状况优于中国(0.5664)、世界(0.5864)平均水平。安徽省水土资源匹配在地市尺度上具有明显空间分异,呈现皖南地区水土资源匹配状况优于江淮之间,而江淮之间又优于皖北地区的水土资源匹配格局。

Matching Analysis of Water and Land Resources in Anhui Province Based on Gini Coefficient

To make a scientific plan for regional agricultural development, matching analysis of water and land resources in Anhui Province from 2000 to 2012 was conducted by constructing the regional Gini curve between water and land resources and calculating the Gini coefficient and the total water resources possessed by per unit area of farmland. The results showed that the average regional Gini coefficient of water and land resources of Anhui Province from 2000 to 2012 was 0.4449, which was more superior to that of China (0.5664) and the world (0.5864). The matching features of the water and land resources in Anhui Province had obviously spatial variation, as the matching degree of southern Anhui Province was better than that of the Yangtze River and Huai River area, while the matching degree of the Yangtze River and Huai River area was better than that of northern Anhui Province.
