雅砻江下游梯级开发对河流生态系统服务功能的影响
Impact of cascade hydropower development in the lower-reach of Yalong river on river ecosystem services
摘要
Abstract
Hydropower is a renewable and sustainable energy source, its development brings along many great challenges. In particular, the unceasing advocated development of cascade hydropower in recent years significantly impacts the complex ecological system of river catchment. This paper takes the cascade hydropower development in the lower-reach of Yalong River as an example, and evaluates the ecosystem services in terms of its product function, support function, regulation function and cultural entertainment function separately, by using market-value method, opportunity-cost method and so on. Finally an evaluation on river ecosystem services can be made by integrating the positive-negative effects. The results show that the index of river ecosystem services in this river reach is increased by 16. 861 billions yuan every year by the three hydropower projects, Jinping I, Jinping II and Ertan. Among all the ecosystem services, hydropower generation and flood storage are the most important, and the hydropower generation ranks first in this reach.关键词
