2005年输水对官厅水库水质的影响、分析及对策

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。

Analysis of the Impact of Water Transportation on Water Quality of Guanting Reservoir in 2005 and Countermeasures Against

The upriver rainfall in Guanting Reservoir has decreased for recent years, which has induced the decreasing of the supply of water gradually. According to the uniform arrangement of the team of continual using and harmonizing about water source in the capital, the Department of Irrigation disposed centralized transportation of water from some upriver reservoirs to Guanting Reservoir. Cetian Reservoir in Shanxi province, Hu Liuhe Reservoir and Friendship Reservoir in Hebei province transported about 0.99 million cubic meters of water to Guanting Reservoir in October17, 2005 in order to release the serious scarcity of water. Based on the comprehensive analysis about the current water quality of Guanting Reservoir and the water quality of this transportation, the article analyses the impact of this transportation on the water quality of Guanting Reservoir and puts forward feasible suggestions, which can provide reference and foundation for management of the water quality of Guanting Reservoir and future water transportation.
