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。The w,ater tempemture structure in reservoir area and downstream have been changed due to the operation of Xiaolangdi Reservoir, which influences the reseroir and downstream river ecosystem. According to the monitoring data of water temperature before and after the op-eration and related research results,this paper summarized the influences of temperature stratification in reseroir area discharge water to the downstream river ecosystem after the operation of Xiaolangdi Reservoir. Then it analyzed the influences on water temperature stratification, and its impacts on water quality. Meanwhile,impacts of the discharged water to the downstream river channel and its impacts on ice run were also analyzed. The results show that there appears temperature stratification after the operation of Xiaolangdi Reservoir,and the water quality diffusion is also affected by the stratification. There is limited impacts on the downstream irrigation, and discharged war^n water is favorable to downstream ice run. But ice prevention is more likely affected by the synthetically effects of water temperature and cascade operation.
