摘　　要：流域景观生态系统具有动态性的特点,总是处于不断变化的时空之中,梯级水电站建设引起的景观生态系统演变是水电开发累积环境影响研究的重点内容之一。研究分析了典型水电工程影响区不同时间段景观生态系统演变趋势。结果表明,水电站在开发前、施工期与蓄水后三个不同时期,区域多项景观生态指数均保持较为一致的变化趋势;长期来看,水电站建设不会使区域景观生态系统类型的完整性与稳定性质量等级发生大的变化。The watershed landscape ecosystem has the characteristics of dynamic and is always in a constantly changing space-time.The evolution of the landscape ecosystem caused by the development of cascade hydropower stations is one of important contents of the research on the cumulative environmental impact of hydropower development.The evolution trend of landscape ecosystem in different periods of typical hydropower project impact area is studied.The results show that,before the development of hydropower station,during the construction period and after the water storage,the regional landscape ecological indexes maintain a relatively consistent change trend.In the long run,the construction of hydropower station will not make a big change in the integrity and stability of regional landscape ecosystem types.
