【 摘 要 】

New method for assessing the environmental risk of water diversion projects is proposed. Fault tree analysis was used to identify risk sources. The project route was divided into four regions: water source region, conveyance region, receiving water region, and drainage region. According to the different characteristics of the four regions, a risk evaluation index system and a multi-layer fuzzy comprehensive evaluation model were established. The results indicated that the environmental risk grade in the water source region was low and those of the other regions were medium-low. This work contributes to the environmental feasibility analysis of water diversion projects.
