【摘要】 分别从土地利用强度、土地投入强度、土地利用经济产出等3个方面构建了3级15个因子的评价指标体系,采用主成分分析法和熵值法对江苏省区域土地集约利用水平进行了定量评估,并分析了区域土地利用集约度的空间格局。从江苏省区域土地利用集约度来看,可将江苏省分为高集约地区、中集约地区和低集约地区3类。其中高集约地区主要分布在苏南地区;中集约地区主要分布在苏中和苏北部分地区;低集约地区主要分布在苏北地区。从区域差异来看,以南北差异为主,东西差异为辅,长江成为江苏省土地利用集约差异的南北分界线。更多还原

【Abstract】 In this paper,an assessment index system of fifteen indexes has been set up from the aspects of land use intensity,land input intensity and land productivity.The degree of regional intensive land utilization was quantitatively evaluated by means of principal component analysis and entropy method.The spatial pattern of the intensivism of regional land use in Jiangsu Province was analyzed deeply.Based on the intensivism of regional land use,Jiangsu Province can be divided into three kinds of regions,i.e.high-intensive,medium-intensive and low-intensive regions.The high-intensive regions are mainly located in the south of Jiangsu,medium-intensive regions in the middle and north of Jiangsu,low-intensive regions in the north of Jiangsu.The regional difference between the north and the south of Jiangsu is greater than that between the east and the west of Jiangsu.The Yangtze River becomes a dividing line of the regional differences of land use between the south and the north of Jiangsu.更多还原
