    摘要:

    基于国内外绿色水电指标体系及评价方法的相关研究,针对流域水电梯级开发环境保护特点和水电工程全生命周期管理,本文构建了3个层次且涵盖河流健康状况、环境管理和社会经济效益3方面的绿色水电综合评价指标体系,建立了绿色水电等级评定的改进的变权物元可拓模型.我们选择大渡河上已建成且投产运行时间较长的深溪沟水电站作为典型代表电站进行绿色水电实证分析,根据收集调查的基础数据计算得出各评价指标的得分,再运用改进变权物元可拓模型对该电站的绿色水电等级进行评定,并进一步对评价指标的敏感性进行分析,验证了所建绿色水电指标体系和评价模型的适用性和有效性.依据绿色水电评价分析成果,我们需要对流域水电开发环境管理进行优化完善,以进一步提高绿色水电评价等级,推进流域水电项目的健康可持续开发.

    Abstract:

    Based on related researches on the index system and evaluation approache of green hydropower at home and abroad, with respect to the characteristics of cascade hydropower development environmental protection in river basin t and the life cycle management of hydropower projects, this study constructed a three-tiered comprehensive green hydropower evaluation index system comprising river health, environment protection and social economy, established an improved matter-element extension model with variable weight for green hydropower rating. This study selected Shenxigou hydropower station which has been built and operated for a long time as the typical hydropower station for empirical analysis.We obtained the score of each evaluation index by computing the data which have been collected and investigated, then utilized the improved matter-element extension model with variable weight to assess green hydropower grade of this power plant, and then analyzed the sensibility of the evaluation index, thus having verified the applicability and effectiveness of this index system and evaluation model. According to the analysis results of green hydropower evaluation, it is necessary to optimize and improve the environmental management of hydropower development in the basin, so as to further improve the evaluation level of green hydropower and promote the healthy and sustainable development of hydropower projects in the basin.
