在2012年北京岩溶水资源勘查成果和以往资料的基础上，对北京市大兴-通州隐伏区岩溶水水化学特征、水质演化规律以及水质恶化原因进行了研究，结果表明，大兴、通州两个储水构造之间的水力联系较弱，岩溶水水化学特征不同。通州地区岩溶水为 H CO 3# SO 42Na # Ca 型，总硬度、溶解性总固体较低，整体水质良好，且与1998年相比没有发生明显变化。大兴地区岩溶水为 HCO 32 Ca# Mg 型，总硬度、溶解性总固体均较高，其中大兴黄村-东高地一带水质较差，其它地区水质良好。与2001年相比，大兴地区岩溶水水质发生恶化，总硬度和溶解性总固体浓度明显升高，且污染范围逐渐扩大。经分析，引起大兴地区岩溶水水质恶化的原因主要有两个：(1)上游垃圾填埋渗滤液和地表污水渗入岩溶水；(2)大量开采岩溶水，改变地下水动力场和岩溶水的赋存条件，促使岩溶水水质恶化。
在2012年北京巖溶水資源勘查成果和以往資料的基礎上，對北京市大興-通州隱伏區巖溶水水化學特徵、水質縯化規律以及水質噁化原因進行瞭研究，結果錶明，大興、通州兩箇儲水構造之間的水力聯繫較弱，巖溶水水化學特徵不同。通州地區巖溶水為 H CO 3# SO 42Na # Ca 型，總硬度、溶解性總固體較低，整體水質良好，且與1998年相比沒有髮生明顯變化。大興地區巖溶水為 HCO 32 Ca# Mg 型，總硬度、溶解性總固體均較高，其中大興黃村-東高地一帶水質較差，其它地區水質良好。與2001年相比，大興地區巖溶水水質髮生噁化，總硬度和溶解性總固體濃度明顯升高，且汙染範圍逐漸擴大。經分析，引起大興地區巖溶水水質噁化的原因主要有兩箇：(1)上遊垃圾填埋滲濾液和地錶汙水滲入巖溶水；(2)大量開採巖溶水，改變地下水動力場和巖溶水的賦存條件，促使巖溶水水質噁化。

Based on the survey results of karst water in 2012 and previous data in Beijing, the hydrochemical charact eristics, the water qualit y evolution, and the causes of groundw ater quality deterioration of covered karst w ater in Daxing-Tongzhou of Bei-jing w ere investigated. The results showed that the hydraulic connection betw een the two groundwat er storage structures in Daxing and Tongzhou is w eak and the hydrochemical characteristics are different. The karst water type is mainly HCO3 # SO 4-Na# Ca in Tongzhou. The total hardness and total dissolved solids are low and the w ater quality is good in the area There is no obvious change in water quality compared with that in 1998. The karst w ater type is mainly HCO3-Ca# Mg in Daxing. The total hardness and total dissolved solids are high. The qualit y is poorer in H uangcun-Donggaodi area. T he water quality deteriorates and the total hardness and total dissolved solids increase compared w ith those in 2001. T he karst groundwater is polluted and the pollution scope expands gradually in Daxing. There are tw o main causes of w at er quality det erioration in Daxing: ( 1) landfill leachat e and pollut ed surface w ater enter into the upstream of karst water; ( 2) long-term excessive exploitat ion of karst ground-w ater changes the groundwater hydrodynamic field and storage conditions of karst w ater.
