摘要
提出了计算“流量”,即计算受水电开发影响的河流生态系统服务功能的价值变化量的评估思路和方法,并以广东省河源市风光水利枢纽工程为案例进行了定量分析。在对河流生态系统服务功能进行分类的基础上,根据河流生态系统服务功能可能受到水电开发影响的现实情况和影响特征,选择适当的生态系统服务功能价值核算的方法和参数,计算受影响的生态系统服务功能的价值变化量。案例研究结果表明,风光水利枢纽工程开发方案引起的河流生态服务功能价值变化的正效益为7 676万元/a,负效益为-3 894万元/a,负效益占到其正效益的一半以上,说明该工程开发对东江河流生态系统的消极负面影响也是不容忽视的,应采取适当的生态补偿措施。
A river provides mankind multifarious ecosystem services. It has great significance to evaluate the effects of hydropower development on river ecosystem services. This paper puts forward a method of ＂flow measurement＂ to evaluate the value of river ecosystem services, and the development of Guangdong Heyuan Fengguang Hydro Project is taken as a case of quantitative analysis. Based on the classification of river ecosystem services and according to the actual situations and characteristics of river ecosystem services influenced by hydropower development, this paper selects appropriate approaches and parameters to calculate the changes of ecosystem service value caused by hydropower development. The results of the case study show that, the positive benefit of Fengguang Hydro Project on river ecosystem services is 76.76 million yuan per annum, the negative benefit is -38.94 million yuan per annum. In addition, the negative benefit of the hydro project accounts for more than a half of the positive benefit, which makes it clear that the negative effects of the hydro project on river ecosystem services should not be neglected and appropriate ecological compensation measures should be adopted.
