摘要
为研究平邑城区集中开采区地下水资源开采前景,在对平邑县重点区水源地水文地质特征的基础上,基于平邑县城区近十年地下水动态资料,建立年末水位与年降水量、灌溉用水量、年开采量关系的多元回归方程,对回归方程计算的水位曲线与实测水位曲线进行拟合,查明了区域地下水位变化的影响因素,并预测地下水资源开采前景。研究显示:该区地下水位受降水量、开采量及水库灌溉的综合影响,平邑城区未来地下水开采量可以达到4万m3/d,比目前的开采水平3万m3/d还有较大的潜力。研究结果对制订区域合理开发利用方案,加强地下水资源的统一调度及合理规划,解决水资源供需矛盾,促进县域国民经济的持续发展具有重要的指导意义。
Pingyi for the study of urban groundwater resources exploitation in the concentrated exploration area prospects,on the water source in pingyi county key area on the basis of the hydrogeological characteristics,based on the information in pingyi county nearly a decade of groundwater dynamic city,set up at the end of the water level relationship with annual precipitation,irrigation water use,annual production of multivariate regression equation,regression equation for calculation of water level curve with the measured curve fitting,The influencing factors of regional groundwater level change are found out and the prospect of groundwater resources exploitation is forecasted. The research shows that the groundwater level in this area is affected by precipitation,exploitation amount and reservoir irrigation,and the groundwater exploitation amount in Pingyi city can reach 40,000 m3/d in the future,which has a great potential compared with the current exploitation level of 30,000 m3/d.The research results have important guiding significance for the formulation of regional rational development and utilization program,strengthening the unified dispatching and rational planning of groundwater resources,solving the contradiction between supply and demand of water resources,and promoting the sustainable development of national economy in the county area.
