摘要
过量开采地下水造成清泥沟地区产生岩溶塌陷,人为污染造成清泥沟水源地供水紧张。在分析清泥沟地下水系统水动力场、水化学场的演化规律的基础上,采用数值法评价水源地允许开采量为4.1万m3/d。为防止岩溶塌陷等水环境问题,提出减采、治污和分散开采等措施。
Exploiting groundwater excessively engenders karst collapses in the Qingnigou area; man-made pollution has caused the shortage of fresh water. Based on an analysis of chemical environment and dynamic environment evolution of groundwater system, the allowable yield of karst water resources is estimated to be 41 000 m^3/d through the numerical model of groundwater currents and this paper also provides countermeasures and decisions to prevent karst collapses and other water environment problems, such as controlling waste water, reducing and decentralizing exploitation of groundwater.
