南水北调不仅是举世瞩目的调水工程,同时也是重大的生态工程。以南水北调中线工程水土保持林草措施生态服务功能为研究对象,将其生态服务功能以物质量与价值量来表征,探讨了其生态服务功能结构及计算方法。经计算,南水北调中线工程水土保持林草措施生态服务功能价值为37 766.07万元。研究可为科学评价南水北调中线工程水土保持林草措施生态效益提供科学依据,并可为开发建设项目水土保持措施效益评价及调水工程生态补偿提供思路。
The South-to-North Water Diversion Project is not only a water diversion project that attracts worldwide attention, but also a major ecological project. Taking the ecological service function of soil and water conservation measures for forest and grass in the midline of South-to-North Water Diversion Project as the research object, the ecological service function is characterized by the quantity and value, and the ecological service function structure and calculation method are discussed. After calculation, the ecological service function of soil and water conservation forest and grass measures in the middle route of South-to-North Water Diversion Project is 377.667 million yuan. This study can provide a scientific basis for scientifically evaluating the ecological benefits of soil and water conservation measures for the Middle Route Project of South-to-North Water Diversion Project, and provide ideas for assessing the benefits of soil and water conservation measures and ecological compensation of water diversion projects.
