地铁建设对城市环境的影响研究———基于网络层次分析法的灰色模糊综合评价

地铁建设过程会从多方面、多层次影响城市环境，这引起了国内外研究者的关注。以这些研究成果为基础构建调查问卷对城市居民进行调查，并用网络层次分析法和灰色模糊评价理论进行综合分析，发现地铁建设对三类城市环境的影响的重要性依次为：城市行居环境、城市生态环境、城市文化景观环境。这说明地铁建设期间，建设者须考虑项目对城市居民衣、食、住、行等日常生活带来的影响，并采取各种相应措施降低项目对城市环境造成的众多负面影响，为地铁建设创造一个和谐有利的环境。

A Grey- fuzzy Comprehensive Evaluation of Subway Construction Impact ~on Urban Environment Based on ANP

The environmental factor is an important content in subway construction. Based on the existing research results, an index system for the impact of metro construction on urban environment had been established. We took Chengdu subway construction as an example and collected mass of data through questionnaire survey. Considering the relevance of evaluation index, the ambiguity and the uncertainty of research problems, we used Analytic Network Process （ANP） and Grey-Fuzzy Evaluation Theory to make a comprehensive evaluation on the impact of the subway construction on the urban environment. The results indicate that the living environment for residents should be attached great importance in the subway construction.
