【摘要】：小浪底水库蓄水后改变了库区及下游河道的水温结构,对库区及下游生态系统造成一定影响。根据小浪底水库蓄水前后的水温监测资料及相关研究成果,分析了蓄水后水库下泄水温对下游河段水生态环境的影响、小浪底水库蓄水运行对库区水温的影响、库区水温分层对库区水质的影响,以及小浪底水库下泄水温变化对下游河道水温和防凌的影响。研究结果表明:小浪底水库蓄水后库区水体开始出现水温分层,且对库区水质扩散有一定影响;春夏低温水下泄对下游农田灌溉影响程度有限,冬季温水下泄有利于下游防凌,但防凌作用主要通过小浪底、三门峡等水库的调度来实现。
[Abstract]:After storing water in Xiaolangdi Reservoir, the water temperature structure of the reservoir area and the downstream river has been changed, which has a certain effect on the reservoir area and its downstream ecosystem. Based on the monitoring data of water temperature before and after the storage of Xiaolangdi Reservoir and related research results, this paper analyzes the influence of the water discharge temperature of the reservoir on the ecological environment of the downstream reach of the reservoir, and the effect of the storage operation of the reservoir on the water temperature of the reservoir. The influence of water temperature stratification on the water quality of the reservoir and the influence of the temperature variation of Xiaolangdi reservoir on the downstream channel water temperature and ice resistance. The results showed that the water temperature stratification began to appear after the water storage of Xiaolangdi Reservoir and had a certain effect on the water quality diffusion in the reservoir area, and the impact of low temperature water discharge on the irrigation of the downstream farmland was limited in spring and summer, and the winter warm water drainage was beneficial to the downstream flood prevention. But the anti-ice action is mainly realized by the operation of Xiaolangdi and Sanmenxia reservoirs.
