摘　　要：地下水是干旱区重要的供水水源,随着人类对地下水的大量开采,地下水位急剧下降,严重影响了干旱区的生态环境。文中基于莫索湾灌区近22年地下水埋深实测数据,通过对比灌区总体与各灌区的埋深变化探究研究区地下水埋深的空间与时间差异,系统分析了该灌区地下水埋深年内变化过程;运用SPSS分析软件对莫索湾地下水埋深变化的影响因子进行了多元回归分析。结果表明,22年来莫索湾灌区地下水埋深总体增加,地下水开采量已逐渐成为影响地下水埋深的主要因素,地下水埋深变化已呈现开采型。2015年后沙漠边缘团场地下水埋深增加趋势逐渐减弱,这是由于地下水开采管理政策的实施。实践证明,严格控制地下水开采是遏制地下水埋深迅速增加的有效手段。Groundwater is an important water source in arid regions. With the exploitation of groundwater, the over-exploitation of groundwater aggravates the deterioration of ecological environment in arid regions. Based on the measured data of groundwater depth in Mosuowan irrigated area in recent 22 years, we explored the spatial and temporal differences of groundwater depth by comparing the changes of groundwater depth between the irrigated area as a whole and each irrigated area, and systematically analyzed the annual changes of groundwater depth in the irrigated area. The factors influencing of groundwater depth change in Mosuowan were analyzed by SPSS. The results show that the groundwater depth in Mosuowan irrigated area has increased in the past 22 years, and the amount of groundwater exploitation has gradually become the main factor affecting the groundwater depth, and the change of groundwater depth has shown mining type. After 2015, the increasing trend of groundwater depth in the farms at the desert edge gradually weakened, while the farms far away from the desert edge showed a gradual recovery trend, which was due to the implementation of groundwater exploitation management policies. Practice has proved that strict control of groundwater exploitation is an effective means to curb the rapid increase of groundwater depth.
