重庆市土地利用与生态环境耦合关系研究

Research on Coupling Correlation between Land Use and Eco-environment in Chongqing City

土地利用与生态环境之间存在着客观的动态耦合关系;利用2003—2012年数据,构建重庆市土地利用-生态环境耦合发展模型,并分析其耦合动态,结果表明:研究期间,土地利用水平与生态环境效益整体呈上升趋势,后者增速更为明显;土地利用水平和生态环境效益的耦合发展度逐年升高,经历了初级、中级、良好、优质4个发展阶段,今后可适当加强土地利用程度。

There is an objective dynamic correlation between land use and eco-environment. Based on the data during 2003—2012, this paper constructs coupling development model of land use and eco-environment of Chongqing City and analyzes its coupling dynamic state. The results show that the land use level and eco-environment return of Chongqing City demonstrate the rising trend during the studying stage,that the latter rise is more significant,the coupling development degree between land use level and eco-environment return rises year by year and undergoes four stages such as primary,middle,good and excellent development and in the future,land use extent can be properly strengthened.
