在已有的研究基础上结合我国现有水电开发对河流生态系统服务功能影响的评价方法,提出了河流生态系统的5种主要生态服务功能:提供产品功能、支持功能、管理及保障功能、调节功能和文化娱乐功能,并采用流量的估算方法、影子价格法和恢复费用法计算了5种主要生态服务功能的价值,找出建坝后大坝每年可能涉及到的效益和损失,为现有大坝可持续管理、生态、经济和环境评价提供依据.
Based on the existing research and combined with the evaluation method of the impact of the existing hydropower development on the service function of the river ecosystem, five major ecosystem service functions of the river ecosystem are proposed: product function, support function, management and guarantee function, regulation Function and cultural and entertainment functions, and calculates the value of five main ecological service functions by using the traffic estimation method, the shadow price method and the restoration cost method, and finds out the benefits and losses that the dam may have in each year after the dam is constructed. Dams provide a basis for sustainable management, ecological, economic and environmental assessments.
