干线公路路畔生态环境AHP层次分析法应用研究

AHP Applied Research on Main Highways Road Bank Ecological Environment

为探讨公路生态环境影响的主、次因素,降低公路污染对其生态环境的影响,以鄢陵G 311、西华S102、周淮S206、项城S238、扶沟S102为调查样点,采用AH P分析法,研究了干线公路路畔生态环境影响的有关情况。结果表明,车辆日混合交通量对公路生态环境影响最大,其次是林带面积和林带密度,植物种类影响最小。在交通量大的路段,应提高林带面积和林带密度,以降低公路污染对公路生态的影响程度。

For discussing the factors of ecological-environmental impact on highway and reducing the ecological and environmental pollution on the highway,the samples were taken from the road Yenling G311,Xihua S102,Zhouhuai S206,Xiangcheng S238 and Fugou S102.Related situation of the main-line highway road bank ecological environment influence were investigated through AHP analytic method.The results showed that traffic vehicle mix was the biggest factor to highway ecological environment,followed by forest area and forest density,minimal impact on plant species.In order to reduce pollution on the highway woodland area and forest density should be raised in busy traffic sections.
