湖南省耕地数量变化与城市化进程相互关系探讨

采用湖南省1997~2007年的耕地面积数据,分析湖南省耕地资源变化及城市化发展过程,并借鉴经济与环境协调度模型,计算了耕地资源与城市化水平的协调度。结果表明,湖南省耕地资源数量随城市化水平的提高,呈现出类似库兹涅茨曲线的倒＂U＂形变动关系;城市化水平与耕地资源数量协调度呈阶段性分布,总体呈现出＂基本协调—不协调—较协调＂的演进趋势。

Analysis of the Relationship between Cultivated Land Quantity Change and Urbanization in Hunan Province

The arable land area data of Hunan province from 1997 to 2007 are used to analyze its change of arable 1and area and urbanization development process.The coordination degree between land resource and urbanization level is calculated by the coordination degree mode between economy and environment.The results shows that there is a significant Kuznets Inverse U Curve in Hunan province,with the improvement of urbanization level,the arable land resources show a decrease first and then an increase.The coordinated index between the urbanization level and arable land resources was a nonlinear relation,the overall trend was from ＂basically harmonious＂ to ＂not harmonious＂ then to＂comparatively harmonious＂ in the past 10 years in Hunan province.
