摘　　要：地下水位控制与水量控制关系十分密切,针对地下水水量-水位双控管理,以长治盆地为研究对象,分析降水量、地下水位动态变化规律及其影响因素,通过建立的3种地下水数理统计模型,运用水均衡法进行水位变幅校核,结果表明:长治盆地地下水属于采补均衡区,降水是当年地下水位变幅的主要影响因子,而当年开采量可能对下一年地下水位变化有影响,将地下水位变幅作为因变量的数理统计模型更加合理;根据浅层地下水非超采区水位控制标准,当长治盆地丰水年地下水位年变幅ΔH≥0.97 m,平水年地下水位年变幅ΔH≈0 m,枯水年地下水位年变幅ΔH≤0.83 m时,可以满足该盆地浅层地下水采补均衡的要求。Taking the Changzhi Basin as the research object,this paper analyzed the precipitation,the dynamic change law of groundwater and the influencing factors and combined the controlled groundwater level and the exploitable groundwater,through different data processing methods,three kinds of mathematical statistical models of groundwater were established and the accuracy of water balance method was checked.The results show that the groundwater exploitation in the Changzhi Basin is still in the equilibrium zone of exploitation and recharge,precipitation is the main factor affecting the variation of groundwater level in that year and the amount of exploitation in that year may have an effect on the variation of groundwater level in the next year.It is more reasonable to take the variation amplitude of groundwater level as de⁃pendent variable.According to the water level control standard of the non⁃overdrawn area of shallow groundwater,the annual variation ampli⁃tude of enough water in the Changzhi Basin is≥0.97 m,the annual variation amplitude of plain water is≈0 m and the annual variation am⁃plitude of dry water is≤0.83 m.
