近几年官厅水库上游降雨量下降,使得官厅水库上游来水逐年减少,蓄水量达到了历史最低点,根据21世纪初期首都水资源可持续利用协调小组统一安排,水利部2003年起部署上游部分水库向官厅水库集中输水。2005年10月17日山西册田水库、河北壶流河水库和友谊水库对北京市官厅水库集中输水0.99亿m3,以缓解本市水资源紧缺的情况,在对现官厅水库水质和此次输水水质的综合评价的基础上,综合分析评价今年集中输水对官厅水库水质的影响,并提出比较合理可行的建议和对策,为输水后官厅水库水质的治理及以后的输水工作提供借鉴和依据。
In recent years, the rainfall in the upper reaches of Guanting Reservoir has decreased, leading to a decrease in incoming water in the upper reaches of the Guanting Reservoir. The water storage capacity has reached a historical low point. According to the unified arrangement of the Coordinating Group on Sustainable Utilization of Water Resources in the capital in the early 21st century, Some reservoirs are transporting water to Guanting Reservoir. On October 17, 2005, Shanxi Cetian Reservoir, Hebei Hu Liu River Reservoir and Friendship Reservoir concentrated 99 million m3 of water to the Guanting Reservoir in Beijing to ease the shortage of water resources in the city. Based on the comprehensive evaluation of the water quality of the Guanting Reservoir and the water quality of the Guanting Reservoir after the water diversion, based on the comprehensive evaluation of the impact of the centralized water delivery on the water quality of the Guanting Reservoir this year, some reasonable suggestions and countermeasures are put forward Reference and basis.
