摘　　要：在对水能资源开发生态效应已有成果分析的基础上,以怒江为例,提出了高山峡谷区水能资源开发中的高梯度生态效应。研究表明:怒江作为我国典型的高山峡谷区,其生态系统的垂直地带性差异明显,水能开发的生态效应在高梯度上差异明显,2000m以下河谷地区受水电工程建设的影响较为直接;海拔2000～2500m之间土壤侵蚀敏感性较高,水电开发面临的生态脆弱性较高;而2500m以上则是怒江重要的生态功能保护区,直接受水电开发的影响较小,水电开发对生态系统的影响更多的体现为间接影响。This article brings out a concept of high gradient eco-effects of hydropower resources in high mountains and valleys based on analysis of existing data.The valley of Nujiang River as a typical example has an ecosystem featured by a high gradient and obvious perpendicular difference and its eco-effects in different high gradients are quite different.The region lower than 2000m above the sea level faces direct effect of hydropower exploitation,the exploitation eco-risk in the region of elevation 2000-2500m is also high due to its great sensitivity in habitant and land erosion,while the impact to eco-system of the region higher than 2500m above the sea level where eco-function protection is important,is indirect and long-time eco-effects become a key issue.
