摘　　要：棘洪滩水库是胶东调水工程青岛端的大型调蓄水库,也是一座典型的平原水库,研究其水文情势与水质的时空变化规律对保证供水水源安全具有十分重要的实际应用价值。根据2001—2009年棘洪滩水库的水文和水质监测资料,从年际、年内和时段进行了调水、供水和水质变化趋势的综合分析。结果表明,棘洪滩水库年调水量为0.39～1.39亿m3,平均值为0.96亿m3;年供水量为0.55～1.19亿m3,平均值为0.95亿m3;通过水量平衡计算得到棘洪滩水库的年损失水量为146.1～648.8万m3,平均值为373.6万m3。棘洪滩水库水质总体上要好于Ⅱ类水质标准,但是总氮指标最大值达到3 mg/L,严重超标。水库水体自净作用下降,内源污染程度加剧。Jihongtan Reservoir is a major regulating reservoir of the Jiaodong water transfer project in Qingdao.It is a typical plain reservoir also.The analysis of hydrological and water quality variation trends have a very important practical value for the water supply security.According to the 2001-2009 Jihongtan Reservoir hydrology and water quality monitoring data,we made the comprehensive analysis of Jihongtan Reservoir water diversion,annual water supply and water quality trends from the annual,year and time periods.The results show that Jihongtan Reservoir annual water transfer is 39-139 million cubic meters,an average of 96 million cubic meters;annual water supply is 55-119 million cubic meters,an average of 95 million cubic meters.The calculated by water balance shows that annual water loss of Jihongtan Reservoir is 1.461-6.488 million cubic meters,an average of 3.736 million cubic meters.The Jihongtan Reservoir water quality is better than Ⅱwater quality standard.However,the indicator of TN is seriously exceeded.The maximum value is more than 3 mg/L.The self-purification of water body is decreasing.Endogenous pollution levels are increased.
