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.
