[Objective] The aim was to study the coupling relationship between economic development and ecological environment.[Method] Firstly,the evaluation index system for the coupling system of economic development and ecological environment in Xi'an City was established,then the dynamic variation of coupling relationship between economic development and ecological environment in Xi'an City from 2001 to 2010 was analyzed by using entropy method,finally some corresponding suggestions were put forward according to the problems in the current development model.[Result] The economic development and ecological environment of Xi'an have made a significant upgrading and improvement from 2001 to 2010,namely showing a stable upward trend on the whole,and were in a well-coordinated development state in 2010.However,the development level of ecological environment obviously lagged behind economic development level after 2005.In addition,there were obvious differences in the development rate of sub-systems,that is,economic efficiency and economic level developed rapidly,while the carrying capacity of ecological environment and economic vitality grew slowly and unstably.[Conclusion] The research could provide theoretical bases for the establishment of strategies for the coordinated development economy and environment in Xi'an City.
