摘要
运用河流连续体理论,分析修建大坝对河流水力学要素的影响.根据水力特征的变化,对河道型水库工程影响区域水力过渡区进行划分,重点研究各个水力过渡区内的水文水力特征、空间结构、物质结构和能量结构的变化及其生态响应.研究结果表明,水文水力特征的变化直接导致了生态环境要素的变化,最终将对河流生态系统产生胁迫.
The influences of dam construction on hydraulic elements of rivers were analyzed by use of the theory of river continuum, and the hydraulic transitional region under influences of river-type reservoir project was classified. The emphasis of the study was placed on hydrological and hydraulic characteristics, variations of spatial structure, matter structure, and energy structure, and ecological response of each transitional region. The research shows that the variation of hydrological and hydraulic characteristics directly causes the variation of eco-environmental elements, and finally leads to the ecological stress on river ecological system.
