针对近年来党河灌区地下水资源的过度开采造成严重生态环境问题的现状，在分析该区地下水变化特征的基础上，重点开展地下水开采的优化分析研究。主要通过水位约束、水量约束、生态环境约束三个方面，建立相应的控制方程，对地下水资源的数量、质量、时空分布特征和开发利用条件作出科学全面的分析和估计。结果表明：根据“地下水快速下降区内机井全部关闭、地下水缓慢下降区内机井部分关闭、基本稳定区机井保持现状、月牙泉周围1 km范围内机井全部关闭”的原则，提出了各乡镇灌溉机井的配置方案，全灌区灌溉机井数量由2009年的2571眼压减到2015年的1041眼和2020年的868眼，并提出不同乡镇的地下水优化开采量。

In recent years,the over-exploitation of groundwater caused serious environmental problems in Danghe River irrigated area. This study took the analysis of groundwater change characteristics as basement,focused on the analysis of the optimization of groundwater exploita-tion. The appropriate equations were established by groundwater level constraints,groundwater quantity constraints and ecological environ-mental constrains,which could scientifically analyze and estimate the quantity,quality and space-time distribution of groundwater resources as well as exploitation conditions. The results show that according to the principle (the groundwater wells with rapid decline in the region should be all closed,groundwater wells with slow decline should be partially closed,groundwater wells in basically stable area should be maintained the status quo and all wells within 1 km range around Crescent Spring must be closed),the wells configuration scheme of town-ship irrigation has been proposed,the number of irrigation wells is reduced from 2 571 in 2009 to 1 041 in 2015 and 868 in 2020,and puts forward optimized amount of groundwater exploitation of different towns in Danghe River irrigated area.
