APPLICATION OF ET-RS-MEA MODEL FOR THE ASSESSMENT ON COMPREHENSIVE URBAN ENVIRONMENTAL QUALITY

Weight plays a crucial role in the process of evaluation and decision-making. In order to overcome the shortcomings of the single method of determining weights, a method of determining weights based on entropy theory and rough set was introduced. Considering that urban environmental quality is a fuzzy concept with multiple indicators, so we used a matter element analysis model. In this paper, a comprehensive evaluation model was established by combination of the entropy theory, rough set and matter element analysis (ET-RS-MEA). Then this new model was applied to evaluate the urban environmental quality of Shenzhen City of China. The results show that as a developed city, a lot of single environmental indicators in environmental quality of Shenzhen City are in excellent and good levels, but the value of complex indicator for environmental quality is in low level. When the method was referenced with local urban environmental plans for verification, the results show that the constructed model is effective for assessing the urban environmental quality.
