Quantitative Evaluation On The Ecological Impact Of Expressway In Hilly Area In East Part Of LiaoNing Province

The construction of expressway had great influence on the local natural environment. This paper took the landscape pattern, ecological footprint and green equivalent ratio into consideration on the evaluation of the region 200 meters away from the mainline road.The hilly area in east part of LiaoNing province is one of the three zones of ecological condition in Liaoning province. The hilly area has great ecological function ,it also belongs to ecological sensitive area,which inclinds to generate ecological destruction under external interference,so it makes great sense to make the research on Quantitative evaluation on the ecological impact of expressway in this area.This paper selects HuanRen-YongLing expressway to do research. First, make the investigation on the present environmental condition.The highway construction results in change in three aspects, including the change of the landscape pattern, the change of Ecological Footprint, the change of the green equivalent.On the other hand, the paper analyses the environmental influence on the economical value and the economical loss.In order to get a final result, a fuzzy mathematic way was used to sum different results into one figure.This research can supplys the research method and index for the research of Quantitative evaluation on the ecological impact of expressway and other kinds of constructions..
