摘　　要：干旱河谷生态环境十分脆弱,其生态修复技术是目前国内最困难的。而近年来我国金沙江流域大规模的水电建设使原本脆弱的生态环境进一步退化,造成泥石流、滑坡等地质灾害的活动更加活跃。在大规模的工程建设区,如不进行以恢复生态功能为目标的植被修复与重建,将会导致巨大的生态安全风险,因而工程扰动区生态修复重建技术是国家急需解决的关键问题。结合恢复生态学理论,对西南水电工程所在区的生态恢复问题进行探讨,确立了恢复生态学理论在干旱河谷生态恢复中的地位,为今后的研究工作提供理论依据。The Dry-hot valley＇s ecological environment is very fragile, and the ecological restoration technology is the most difficult in domestic at present. In recent years, it makes the originally fragile ecological environment further degraded after the extensive hydroelec- tric constructions are built in the Jinsha River. The geological hazards, such as debris flow and landslide, are more active. In the extensive engineering construction, if the vegetation restoration and rebuild doesn＇t take effect as its goal, it will cause enormous ecological safety risk. So the key problem is to establish the technology of ecological restoration in the project perturbation area. This paper combining the theory of restoration ecology discussed the ecological restoration question of the southwest hydroelectric project area, established the position of the theory of restoration ecology in the Dry-hot valley＇s ecological restoration, and it offers theoretical foundation for the further research.
