在格尔木山前平原区水文地质条件基础上,结合多年地下水位监测资料,对格尔木河冲洪积平原区的多年水位动态特征及其影响因素进行了分析研究,总结出该地区的地下水动态类型.格尔木山前平原区3个不同区域由于赋存条件及开发利用条件的不同,地下水动态类型分异显著.研究区地下水整体流向与地形起伏相一致,自南向北径流,区域上流场形态变化不大.冲洪积扇中上部地下水多年动态处于平衡状态,近年来由于开采力度加大,地下水位呈急速下降趋势,地下水动态类型为水文-径流型;冲洪积扇下部地下水位以区域性下降为主,地下水动态类型主要为蒸发型;冲洪积扇西翼水源地附近由于地下水调蓄能力较强,地下水位总体呈稳定并局部有上升趋势,地下水动态类型为水文-人类活动型.
Based on the hydrogeological conditions in the former Golmud plains area and the multi-year groundwater table monitoring data, the dynamic characteristics of the water level in the alluvial plains of the Golmud and its influencing factors were analyzed and studied, and the dynamic types of groundwater in the area were summarized. There are significant differences in the dynamic types of groundwater in three different areas of Golmud Piedmont, due to the different conditions of occurrence and development and utilization of the groundwater.The overall groundwater flow in the study area is consistent with the topography and undulation. From south to north, The groundwater level in the alluvial fan has been in a state of equilibrium for many years. In recent years, due to the increase of exploitation, the groundwater level has been rapidly declining, and the dynamic type of groundwater is hydrological-radial type. The groundwater level in the lower part of the alluvial- The main dynamic type of groundwater is evapotranspiration. Because of the strong groundwater storage and storage capacity, the groundwater level is generally stable and partially upward trend, and the dynamic type of groundwater is hydrological-human activity type.
