采集南水北调北京蓄调池附近地下砂样、地下水水样、丹江口水库水样，通过室内试验模拟含水层方法，分析不同比例的丹江口水库水、地下水与含水层介质混合后的水化学作用，探讨水化学成分随时间的变化规律。结果表明，模拟含水层在可溶盐溶解作用、矿物溶解-沉淀作用、微生物作用、阳离子交换吸附作用等影响下，各项水质指标都发生了变化，但均符合地下水质量Ⅰ类或Ⅱ类标准。
採集南水北調北京蓄調池附近地下砂樣、地下水水樣、丹江口水庫水樣，通過室內試驗模擬含水層方法，分析不同比例的丹江口水庫水、地下水與含水層介質混閤後的水化學作用，探討水化學成分隨時間的變化規律。結果錶明，模擬含水層在可溶鹽溶解作用、礦物溶解-沉澱作用、微生物作用、暘離子交換吸附作用等影響下，各項水質指標都髮生瞭變化，但均符閤地下水質量Ⅰ類或Ⅱ類標準。

In this study , underground sand specimens near the water-regulating tank in Beijing for the South-to-North Water Diversion Project , groundwater samples , and Danjiangkou Reservoir water samples were collected . Through laboratory simulation of the aquifer , the water hydro-chemical action of mixed reservoir water , groundwater , and aquifer media with different rations were analyzed , and the change in the hydro-chemical composition with time was examined .Experimental results showed that the water quality indices changed due to soluble salt dissolution , mineral dissolution-precipitation , microbiological action , and cation exchange adsorption , but the water quality met the grade I or II standards of the groundwater quality standards of China .
