【摘要】 流域梯级开发可带来发电、防洪、灌溉等综合效益,促进我国经济社会的快速发展,但同时引发了很多区域生态环境方面的问题,包括水库淹没与移民,泥沙淤积、河道变化、地质灾害、水生生物、水土流失等。针对流域梯级开发存在的上述生态环境问题,初步提出加强建设项目的前期管理、加强施工过程中的监督和管理、建立和完善生态补偿机制、合理优化开发与运行方式等主要对策。更多还原

【Abstract】 The original natural basin is one integral ecosystem,while the basin cascade development intercepts the continuum of the river and puts stress on the ecosystem so as to destroy the coo-balance of the whole system.The emerging ecological environment problems such as the influence on sediments and river channel, the reservoir flood and immigrants,the influence of water body’s change,the influence on fish and biological species,the geological disaster as well as the loss of soil and water is analyzed during the process of the basin cascade development.In order to decrease the disadvantageous impacts of river cascade development,the corresponding engineering or non-engineering measures are put forward in different phases such as the planning,construction and operation.The aim to build friendly-environment water projects and realize the sustainable development of water resources is arrived at.更多还原
