Based on the fuzzy AHP method, an evaluation index system for eco-restoration engineering on the slope of a hydropower project is established with twenty indexes, which can combine qualitative analysis and quantitative analysis. It includes four kinds of indexes which are the effect of soil and water conservation, the effect of habitat material improvement, the effect of ecology and the effect of landscape. According to the problems found through the analysis, five targeted regulatory technologies were developed and then applied to eco-restoration engineering on the slopes of the Guangzhao, Nuozu, Xiaowan, Xiangjiaba and Pubugou hydropower stations, respectively. And the eco-regulation measures have effectively solved the existing problems. Through eco-regulation, the evaluation result of each has greatly increased and these measures have clearly improved the current conditions of the five typical engineering cases. This shows that the regulatory technologies are effective and that the evaluation index system is applicable.
