The Synthetic Evaluation of Eco-Environment in Liaoning Province of China Based on GIS

摘要

In recent years,there has been an increasing attention on the regional eco-environment,especially when it comes to the issues of sustainable development.Thus,the synthetic evaluation of eco-environment quality is necessary,which is helpful to clarify its current state.In this paper,the eco-environment equality of Liaoning Province is evaluated synthetically by a new method combining GIS (Geographical information system) with AHP (Analytic hierarchy process)-Entropy.The results showed that the regions including Shenyang,Dalian and Dandong had a relatively good eco-environment quality,while the ecoenvironment quality of Chaoyang and Fuxin is bad in the year of 2009.Moreover,it was obvious that the eco-environment quality of most regions in Liaoning Province had a downtrend during 2005 and 2009.Overall,the entire eco-environment quality of Liaoning Province declined rapidly due to the high intensity of human activities in recent years.
