摘要
根据水电工程扰动区生态修复边坡的特点,从生态修复边坡的水土保持效应、生态效应、基材改良效应及景观效应4方面出发,建立了水电工程扰动边坡生态工程效应评价指标体系。评价指标体系包含15个评价指标,同时采用层次分析法确定评价体系中各指标权重,利用评价体系对各恢复样地生态护坡效应进行评价,评价结果与现场调查和试验结论一致,表明评价指标体系具有可靠性和可推广性。
Based on the characteristics of ecological restoration slope in the area disturbed by hydropower project construction, an ecological engineering effect evaluation index system is established from 4 aspects of soll and water conservation effect, ecological effect, base material improvement effect and landscape effect. The system contains 15 evaluation indexes. We use AHP to determine the weight of evaluation indexes, and use evaluation system to evaluate the slope ecological effect of each restoration sample. The evaluated results coincide with the in - situ observation, and the evaluation index system has a reliability and popularization value.
