摘要
小水电建设促进经济发展的同时,对当地生态环境也造成一定的破坏。开展水电梯级开发对河道生态需水影响对于水资源的合理开发与保护具有重要意义。针对武义麻阳港小流域水电开发现状,从河道内与河道外两方面对流域进行了生态需水量核算;并对流域梯级开发电站为满足减水河段生态环境需水要求的最小下泄流量进行了初步分析。
Construction of small hydropower, while promoting economic development, and also causedsome damage to the local ecological environment. To study the impact of hydropower cascadedevelopment on river ecological water demand is of great significance for the rational development andprotection of water resources. It was estimated which the ecological water demand for the two sides of thein-stream and out-stream respectively, based on the present situation of hydropower development ofMayanggang River basin; And preliminary analysis the lowest discharge flow of cascade developmenthydropower station to suffice the eco-environmental water demand of reducing reach of the river.
