Research on Risk Assessment Method of Eco-environment for Towns in China : A Case Study from Xinzhou, Wuhan

摘要

As heavy contaminative industries are rushing into suburban areas from urban areas with the rapid development of urbanization in China, eco-environment quality of towns largely deteriorated.Currently, little research has been devoted to evaluation methodology of eco-environmental quality with regard to towns, as a result of little attention being paid to Eco-environment Problems of Town (EPT) in China. In this paper, a systematic index system for ecoenvironment evaluation of towns was proposed according to law of index. Then, a model GRP-IAHP-R was brought forward based on these index and summingup results of previous studies.At last, a case study of Xinzhou district of Wuhan city was carried out by collecting field data and field survey.Having good consistence with results of theoretical analysis and authentication, the method not only evaluate ecoenvironment in a more feasible, reliable and objective way, but also evaluate Eco-environment Quality for Town (EQT) comprehensively and objectively.
