摘要
为了判断公路建设对区域环境的总体影响,按照客观性、科学性、完整性等原则选取了公路建设项目环境影响评价指标。将公路建设对各环境因子的影响分为负面影响很大、负面影响小、基本无影响、正面影响小、正面影响大5种不同的影响程度,引入了改进的层次分析法(IAHP)确定权重,采用模糊数学方法进行综合评价,并以安康-毛坝高速公路为例进行评价分析。结果表明,模糊综合评价是一种科学合理、简单可行的公路建设项目环境影响评价方法。
In order to evaluate the overall impacts of highway construction project on the district environment, this paper selects environmental impact assessment indexes from the views of objectivity, science and intergrated principle. Based on the improved AHP method, a fuzzy mathematics method is adopted to evaluate environment impact of highway construction project. As an example, Ankang--Maoba expressway construction project is evaluated. The result shows that fuzzy comprehensive assessment is a scientific, reasonable and simple method for environmental impact assessment of highway construction project. 1 tab, 12 refs.
