Evaluation of Ecological Benefit of Vegetation Restoration on Rock Slope:A Case Study of Pulang Copper Mine in Shangri-La
摘要
Abstract
The vegetation restoration project of rock slope in Pulang copper mine in Shangri-La,Yunnan Province was taken as the research object,and the ecological benefit evaluation model was established by simulation test and shadow engineering method.The fuzzy comprehensive evaluation model was established based on the ecological benefit evaluation results,and the importance of each index was analyzed.The results showed that both slope and rainfall intensity had influence on the soil conservation effect of vegetation.The optimal soil conservation effect could be obtained by mixed sowing of group A plants or single sowing of group B plants.The economic value of carbon fixation and oxygen release,dust reduction,forest nutrient accumulation,SO2 purification and water conservation brought by each hectare of mine vegetation restoration was 1131.374,814.776,456.058,4.402 and 9.718 yuan/a,respectively.The ecological benefits brought by the five projects were ranked as follows:forest nutrient accumulation benefit＞dust reduction benefit＞carbon fixation and oxygen release benefit＞water conservation benefit＞SO2 purification benefit.关键词
