| 摘 要： | 笔者在充分调研和综合分析研究金沙江、雅砻江、大渡河水电工程区岸坡生态地质环境条件和主要生态环境地质问题及其环境演化效应的基础上.按照分类评价思想和原理.初步探讨了流域梯级水电工程开发对生态地质环境影响评价的思路与方法,初步提出以斜坡(岸坡)稳定性评价子系统、水土流失与水库淤积评价子系统、生态环境演化评价子系统和社会经济发展影响子系统等四大类子系统为主干的梯级水电开发对生态地质环境影响评价系统.初步建立了四大类评价指标体系,讨论了评价方法与成果表达方式,供大家讨论。 |

| Abstract: | Full investigation and comprehensive analysis have been conducted on the bank slope ecological geo- environment in the Jinsha River,Yalong River and Dadu River hydroelectric project areas and main problems in the eco-environmental geology and environmental evolution effect.On that basis and according to the classification assessment concept and principle,the authors have explored the concept and method of assessment of the effect of cascade hydropower development on the ecological geo-environment in the drainage basin, established an assessment system of the effect of cascade hydropower development on the ecological geo- environment,which consists dominantly of four major subsystems,namely,the assessment subsystem of slope (bank slope)stability,assessment subsystem of soil erosion and reservoir sedimentation,assessment subsystem of the eco-environmental evolution and subsystem of the influence of social economic development,initially established four major assessment index systems and discussed the assessment method and expression way of assessment results for discussion. |
| Keywords: | cascade hydropower development in the drainage basin ecological geo-environment impact assessment assessment index system Jinsha River |
