摘　　要：以云南香格里拉普朗铜矿的岩石边坡植被修复工程为研究对象,通过模拟试验和影子工程法构建了其生态效益评估模型;再根据生态效益评估结果建立模糊综合评价模型,对各评价指标的重要性进行了分析。结果表明:坡度和降雨强度对植被的土壤保持效果均有影响,采用A组植物混播或B组植物单播的处理可以获得最优的土壤保持效果;岩石边坡植被修复工程固碳释氧、减少粉尘、林木营养累积、净化SO2、涵养水源的经济价值分别为1131.374、814.776、456.058、4.402、9.718元/a;5个项目的生态效益表现为林木营养累积效益>减少粉尘效益>固碳释氧效益>涵养水源效益>净化SO2效益。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.
