| 摘 要：【目的】探明新疆石河子-昌吉地区地下水位变化规律及其驱动因素。【方法】基于2016―2020年研究区44眼监测井逐月地下水埋深数据，划分地下水动态类型，绘制了多年地下水埋深累计变幅分区图和高低水位期地下水流场对比图，综合直线趋势分析方法和灰色关联分析方法对地下水位动态特征及其影响因素进行分析。【结果】区内潜水动态类型为灌溉入渗-开采型和水文-开采型，承压水动态类型为开采型。石河子市地下水位呈快速上升趋势（埋深变幅多为-3～-2 m）；玛纳斯县南部地下水位快速上升（多为-4～-3 m），北部水位快速下降（多＞5 m）；呼图壁县地下水位快速下降（多＞5 m）；昌吉市地下水位动态变化相对缓慢，以缓慢下降为主（多为2～3 m）。石河子市和玛纳斯县南部水位回升主要取决于低水位期，北部地下水漏斗区局部水位回升则相反；呼图壁县水位持续下降受高、低水位期共同影响；昌吉市水位动态稳定，与河流补给作用有一定关联。【结论】耕地面积、地下水开采量和地表水源供水量是潜水水位变化的主控因素，承压水水位变化主要受耕地面积和地下水开采量的影响。 |

| Abstract:【Objective】The purpose of this paper is to explore the variation law of groundwater level and its driving factors in Shihezi-Changji region of Xinjiang.【Method】Based on the study area from 2016 to 2020 in buried depth data of 44 groundwater level monitoring wells monthly, the groundwater dynamic type was divided, the groundwater depth accumulative variation zoning map and groundwater flow field contrast figure in high and low water level period were drawed, the groundwater level dynamic characteristics and its influencing factors were analyzed using linear trend analysis method and gray relation analysis method.【Result】(1)The dynamic types of unconfined groundwater in the study area were irrigation infiltration - exploitation type and hydrology - exploitation type, whereas the dynamic type of confined groundwater was exploitation type. (2)The groundwater level in Shihezi city showed a rapid rising trend (the variation amplitude of buried depth was mostly -3～-2 m); in the south of Manas County, the groundwater level rose rapidly (mostly -4～-3 m), whereas in the north of Manas County, the water level decreased rapidly (mostly > 5 m). The groundwater level in Hutubi County decreased rapidly (mostly > 5 m). The dynamic change of groundwater level in Changji city was relatively slow, with a slow decrease (mostly 2～3 m). (3)The rise of water level in the southern part of Shihezi city and Manas County mainly depended on the low water level period, whereas the local water level rise in the northern groundwater depression cones area was the opposite; The continuous decrease of water level in Hutubi County was influenced by both high and low water level periods. The dynamic stability of water level in Changji City was related to the replenishment of rivers.【Conclusion】The area of cultivated land, the amount of groundwater extracted and the amount of surface water supplied were the main controlling factors of the change of unconfined groundwater level, whereas the change of confined groundwater level was mainly affected by the area of cultivated land and the amount of groundwater extracted. |
