以新疆渭库绿洲为研究对象,利用研究区近11 a的地下水埋深数据,分析了渭干河-库车河绿洲地下水埋深的时间及空间分布特征。结果显示该区域地下水埋深从灌区上部往下部有明显的上升趋势,春季地下水位最高;空间变化具有离绿洲越远地下水位越浅,离渭干河河道越近,地下水位越浅的特点。这与地形、水文地质条件、土地资源开发、灌排强度、地表蒸发、化学肥料和农药的使用密切相关。
Taking Weiqiku Oasis in Xinjiang as the research object, the temporal and spatial distribution characteristics of groundwater depth in Weigan - Kuchahe Oasis were analyzed based on the groundwater depth data of the past 11 years in the study area. The results show that the groundwater depth in this area shows a clear upward trend from the upper part to the lower part of the irrigation area, and the spring water table has the highest groundwater level. The spatial variation has the characteristics that the shallow groundwater table is farther away from the oasis and closer to the Weigan River. This is closely related to topography, hydrogeological conditions, land resource development, intensity of irrigation and drainage, surface evaporation, use of chemical fertilizers and pesticides.
