Abstract:There is an objective dynamic correlation between land use and ecoenvironment. Based on the data during 2003—2012, this paper constructs coupling development model of land use and ecoenvironment of Chongqing City and analyzes its coupling dynamic state. The results show that the land use level and ecoenvironment 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 ecoenvironment 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.
