水利水电项目的环境经济损益分析方法

作为提供可再生能源的水利水电项目,在获得综合效益的同时也会对生态环境带来负面影响,需要对其进行环境经济损益评价。采用环境经济损益分析的理论和原则,结合水利水电项目的特点,以糯扎渡水电站为例,初步探讨了水利水电项目环境经济损益分析的方法。分析结果表明:糯扎渡水电站的工程生态环境总效益为35.65亿元/a,环境资源的总损失约为8.1亿元/a,项目建设在环境经济方面完全可行;并就水电工程建设项目环境质量损益的经济评价提出了笔者的看法,供同行参考与借鉴。

Environmental Economic Profit and Loss Analysis Method forWater Conservancy and Hydropower Projects

Water conservancy and hydropower projects which can provide renewable energy source would bring about comprehensive effect and would also have negative impact on the ecological environment. It is necessary to conduct environmental economic profit and loss evaluation. Based on the theoretical and principles of environmental economic profit and loss analysis, combined with the characteristics of water conservancy and hydropower projects, the method of environmental economic profit and loss analysis of water conservancy and hydropower projects was preliminarily discussed taking Nuozhadu Hydropower Station as an example. The analysis results show that the ecological environment total benefit of Nuozhadu Hydropower Station is 3.565 billion yuan per year, and the total loss of environmental resources is 810 million yuan per year. The project construction is completely feasible in the environmental economy. And the authors put forward their own views on the economic evaluation of environmental quality loss and benefit of hydropower project construction, for peer reference.
