玉曲河流域水电开发生态风险评价指标体系研究

Research on Index System of Ecological Risk Assessment of Hydropower Development in Yuqu River Watershed.

水电开发在改善区域能源结构和促进社会经济发展等方面发挥了积极的作用,同时对流域生态环境造成了难以恢复的影响。为准确分析水电开发对流域生态风险的影响程度,本文以玉曲河流域水电开发为例,从生态风险源、生态风险受体及社会经济三个方面构建指标体系,建立相应的评判标准,对水电开发前后的生态风险进行对比分析,研究结果表明:水电开发在一定程度上加剧流域生态风险程度。并为流域生态风险评价指标体系构建提供参考依据。

Hydropower development has played a positive role in the area of improve energy structure and promote social and economic development,while the watershed ecological environment caused by the influence of difficult to restore. In order to accurately analysis of the effect of hydropower development on watershed ecological risk degree,this paper use the hydropower development of Yuqu River watershed as a example,build the index system from three aspects: ecological risk source,risk receptor and the social economy,established the corresponding evaluation standard,Compare and analyze the ecological risk of before and after the development of hydropower,Research results show that the hydropower development increased watershed ecological risk degree to a certain extent,meanwhile provide a reference for the building of watershed ecological risk evaluation index system.
