Minority regions are the important ecological barriers in China.Evaluating and analyzing performance of environmental protection in a scientifical way is the important and effective way to calculate and promote the environmental construction in minority regions.This paper,from four aspects:environmental comprehensive development,reduction discharge of three wastes,natural calamities control and rural construction inputs,first uses AHP to construct evaluation indicator system of performance improvement in environmental protection in China’s 9 minority regions and then makes an empirical study in Inner Mongolia,Guangxi,Hainan,Guizhou,Yunnan,Gansu,Qinghai,Ningxia and Xinjiang.The result shows that compared with 2006,the ecological and environmental condition was greatly improved in 2009,and its comprehensive level also showed significant increase; environmental protection performance of Xinjiang,Qinghai,Gansu are restricted by reduction discharge of three wastes indicator;natural calamities control index of these regions are lower than national level and rural construction inputs indicator is the main limited factor in the improvement of environmental protection performance in Guizhou.Consequently,this paper puts forward relevant policy suggestions,which include popularizing resource--saving and environmentally-friendly industrial model so as to scientifically use energy,implementing the relevant policies in minority regions to promote the harmonious development in minority regions,pushing forward the construction of new socialist countryside in minority regions to quicken the process of building well-off society and developing environmental non-governmental organizations so as to improve all people’s awareness in protecting environment.
