中文摘要 | 河流水电开发在缓解水资源和电能短缺问题的同时,对库区及其下游的生态环境也带来了一些负面效应。这些影响主要体现在:(1)工程施工恶化周边生态环境;(2)水库蓄水导致库区生态变迁;(3)引水式电站改变坝下缺水段生境特征;(4)河流水沙变化破坏下游河道及河口区的水一盐、水一沙平衡。针对水电开发所带来的这些问题,提出了几条应对措施,以弱化其负面影响。这些措施包括:(1)进行流域开发规划,重视水电开发规划的环境影响评价工作;(2)优化工程设计.,预防或减少水土流失;(3)加强工程环境监理,明确环境管理职责;(4)加强水电建设项目的生态化;(5)优化水库运行管理,减轻生态冲击。 |
英文摘要 | River-hydropower-development could mitigate the pressure caused by water resoulx2e scarcity and~rler gY deficiency.Simultaneously,it also brought negative impacts on ectyenvironment of reservoir area and down. stream area as following:(engineering construction could deteriorate surrounding eco-environment;(2)reservoir storage leads to ecologic change in reservoir area;(3)diversion type power plants leads to change of eco-environ meant features of downstream water-deficient section;(4)change of stream flow and sediment delivery capacity breaks the balance of water-salinity and of water-bedload.To solve or lessen the negative impacts.some counter— measures are discussed in this paper,including:(1)conducting river basin development planning while impor— tance being attached to environment impact assessment 0f hydropower development project;(2)optimizing engi— neering design to prevent or alleviate soil and water loss;(3)enhancing supervision of engineering environment and confirming personnel responsibilities for environment administration;(4)integrating hydraulics with eeolo— gY to develop hydropower prciect;(5)optimizing reservoir operation management to Iessen negative impacts on eco -envlronm ent. |
