Quantitative Risk Analysis of Eco-Environment Quality in Towns

Shang Lingling,Lin Yanxin(Institute of Economics and Management,Shenyang University of Chemical Technology,Shenyang 110142,China)  
With China's gradual urbanization drive,many highly contaminative industries migrated to suburban districts and the deterioration of eco-environment quality in towns is evident.At present,the evaluation methodology of eco-environmental quality with regard to town is insufficient due to little attention was paid to eco-environment problems of towns in China.The 43 preselected indicators for town were confirmed by frequency statistics method based on studying information and summing-up of previous research results.The preselected indicators were selected by using analysis theory and practice(ATP),Delphi expert consultation law and rough set attribute reduction method(RSARM).A systemic indicator system for eco-environment evaluation of town was put forward.Then,a model GRP-IAHP-R was brought forward based on these indicators and summing up results of previous studies.At last,case study of Z district of Wuhan city was carried out by using the indicator system and model by collecting field date and doing field survey.Results of theoretical analysis and authentication showed that this method not only can evaluate eco-environment feasibly,reliably,objectively,but also can be to carry out in evaluation of eco-environment quality for town comprehensively and objectively.It is a suitable method for eco-environmental quantitative risk analysis of Chinese towns.
