摘要
针对三峡水库蓄水以来库区支流出现的水体富营养化问题,研究并建立了基于日调节过程的非汛期生态调度模型,并对三峡水库非汛期的日调节调度方案进行模拟分析,对进行日F调节后水库及主要支流的水动力特性和水质变化情况进行了分析比较。分析结果表明:通过改进方案的非汛期日调节过程的优化,可使库区及支流的水体富营养化问题得到明显缓解,继而可有效地改善库区的生态环境。
According to water eutrophication of tributaries in Three Gorges Reservoir area after the impoundment,we established ecological operation model based on daily regulating hydropower station running.The daily operation schemes in non-flood season in Three Gorges Reservoir area were simulated and analyzed.The hydrodynamic characteristics and water quality changes of reservoir and tributaries were compared after the daily regulation of the reservoir.The results show that by the daily regulating hydropower station running,the water eutrophication of tributaries was significantly alleviated;furthermore,the ecological environment of reservoir area can be improved efficiently.
