摘　　要：为研究山东省鲁西北平原地下水资源情况,为地下水资源的可持续利用提供合理化建议,采用水均衡法对研究区地下水资源进行评价,并采用开采系数法对研究区地下水可开采潜力进行分析。结果表明,均衡期内研究区总补给量为1224411.90×10^(4)m^(3)·a^(-1),总排泄量为1187412.52×10^(4)m^(3)·a^(-1),补排差为47380.47×10^(4)m^(3)·a^(-1),研究区地下水资源处于正均衡状态;多年来平均计算均衡差较小,地下水处于相对稳定状态;全区可开采资源量为1040750.11×10^(4)m^(3),现状开采量为655550.26×10^(4)m^(3),潜水开采潜力指数为1.59,地下水资源具有开采潜力,但是开采潜力较小,需要对地下水资源进行合理规划。In order to study the groundwater resource and ensure the sustainable utilization of groundwater resource in the plain of Northwest Shandong,this paper uses the water balance method to evaluate the groundwater resources in the plain of Northwest Shandong,and then uses the extraction coefficient method to analyze the exploitable potential of the groundwater in the Northwestern Shandong Plain.The results show that the total recharge of the study area during the equilibrium period is 1224411.90×10^(4)m^(3)a^(-1),the total excretion amount is 47380.47×10^(4)m^(3)a^(-1),and the difference is 47380.47×10^(4)m^(3)a^(-1).It is shown that the groundwater resource is positive balance in the study area.However,the average equilibrium difference is small,which indicates that Groundwater has been in a relatively stable state for many years.According to the analysis of exploitable potential,the exploitable resource in the plain of Northwest Shandong is 1040750.11×10^(4)m^(3),the current exploitation is 655550.26×10^(4)m^(3),and the potential index of unconfined water exploitation is 1.59.It shows that the groundwater resource in the plain of Northwest Shandong have potential for exploitation.However,the exploitation potential is small,and reasonable planning of groundwater resources is required.
