公路建设对环境影响的评价

Evaluation on Impact of Highway Construction on Environment

介绍了公路建设对环境影响的现状,分析了嫩呼公路的设计、施工、运营阶段的环境特点,找出了嫩呼公路各污染源产生的原因,提出了保护、治理措施。运用了指标赋权法对保山市市区公路的各种环境指标进行数据分析,得出了二氧化硫、氮氧化物等尾气组成元素对公路环境影响最大的结果,为公路环境治理提供有力依据。并应用SPSS软件对公路污染因素进行主成分分析,得出了二氧化硫、氮氧化物和尘降的增加会相应导致TSP减少,氮氧化物和TSP的增加会导致尘降减少的结论。

The developing status of effects of highway construction on environment was introduced. The environmental characteristics of Nenjiang-Huma Highway were analysed during the design, construction and operation phases, and various pollution sources were fotmd out. Moreover, some protective measures were put forward. Different environment factors were analysed by index weight method using the urban highway in Baoshan City as an example. Results show that sulphur dioxide and nitrogen oxide compound have the most significant influences on highway environment, which provides a reliable basis for environment renovation of highway. The result form the principal component analysis of pollution factors by SPSS shows that the increasing of sulphur dioxide, nitrogen oxide compound and falling dust particles results in the decrease of the Total Suspended Particles （TSP）, and the aggrandizing of nitrogen oxide compotmd and TSP leads to the reduction of falling dust particles.
