Construction of Ecological Environmental Impact Assessment Indicator System of Highway Construction in Ecologically Sensitive Areas of Xinjiang
According to the construction project of Xinjiang Nalati-Baluntai Expressway,analyse the environmental problems generated during the construction period of the highway,adopt the literature analysis and frequency analysis method,combine with the expert o-pinion on the screening of indicators,and study the principles and methods of ecological environmental impact evaluation indicators combined with the characteristics of ecologically sensitive areas,establish the ecological environmental impact during the construction period of the highway in ecologically sensitive areas,which is constituted by 5 level two indicators and 17 level three indicators.Through hierarchical analysis method to assign weights to each indicator,the results show that the weights of vegetation coverage,tree felling,TSP,ecological restoration rate of temporary occupation,average construction daytime LAep,CODcr and petroleum concentration in the second-level indicators account for a large proportion of the weights,and the evaluation results are in line with the reality.
