The ten districts of Shaanxi Province was selected as the study area. The coupling relationship be tween economic development and ecological environment was analyzed using entropy method

coupling degree model and GIS technology. According to the cluster analysis

the coupling relationship could be divided into five types. The spatial characteristics and internal differences of coupling levels were discussed. Overall

the coupling relationship between economic development and ecological environment in the province was low and needs to be improved. Each level of coupling relationship showed obvious local convergence

and the coupling levels next to each other displayed strong geographic proximity.
