在沙漠公路沿线设置了地下水监测断面,获得了定位实测的地下水位数据,实测资料结合水文资料、地下水地表水相互转化理论以及地下水动力学原理,分析了地下水位的时空变化规律.认为地下水位埋深空间分布主要受沙丘高度和地形变化影响.地下水位随时间变化的主要影响因素可分为4类,就影响水位变化的幅度而言,防护林工程抽水>垂直排泄作用>河流流量变化>渗流补给作用;而就影响范围而言则渗流补给作用影响范围最大,防护林工程抽水影响范围最小.地下水位的年际变化呈自然波动状态.
The groundwater monitoring section was set along the desert highway and the groundwater level data were obtained. The measured data combined with the hydrological data, groundwater surface water conversion theory and the principle of groundwater hydrodynamics, analyzed the temporal and spatial variation of groundwater table. The deep space distribution is mainly affected by dune height and topography changes.The main influencing factors of groundwater level with time can be divided into four categories, in terms of affecting the magnitude of the water level change, the shelterbelt pumping> vertical excretion> river flow change> seepage recharge While in terms of impact range, the effect of seepage recharge is the largest, and the influence of pumping water in shelter forest project is the smallest. The interannual variation of groundwater table shows a natural fluctuation.
