【摘要】：吐鲁番盆地位于我国西北内陆,蒸发强烈,降水稀少,地下水是非常重要甚至是唯一的淡水资源。为了能够探明吐鲁番盆地地下水资源量的构成,通过数据收集、现场调查和水文地质实验获得了一系列的参数,利用GMS软件建立了吐鲁番盆地地下水的非稳定流模型;并且基于现状开采条件下对吐鲁番盆地的地下水做了20 a预测。模拟结果显示:吐鲁番盆地的地下水可采资源量约为4.42×10~8m~3·a~(-1),现状开采条件下到2031年的地下水位下降幅度最高为13 m。由于吐鲁番盆地开采地下水主要用于农业灌溉,故吐鲁番盆地的绿洲面积不会减少,但为了合理利用地下水资源,应该调节该地区的供水结构,加大农业用水节水设备的使用。
[Abstract]:The Turpan basin is located in the inland of Northwest China. The evaporation is strong and the precipitation is scarce. The groundwater is very important and even the only fresh water resources. In order to detect the composition of the groundwater resources in the Turpan basin, a series of parameters are obtained through data collection, field investigation and hydrogeological experiments, and the Turpan basin is established by using the GMS software. The unsteady flow model of ground water is made, and the groundwater of Turpan basin is predicted by 20 A under the condition of current exploitation. The simulation results show that the groundwater recoverable resources in Turpan basin are about 4.42 * 10~8m~3. A~ (-1), and the lowest level of groundwater level in 2031 is 13 M. due to the opening of the Turpan basin. The area of ground water is mainly used for agricultural irrigation, so the area of oasis in Turpan basin will not be reduced, but in order to make rational use of the groundwater resources, the water supply structure in this area should be adjusted and the use of water saving equipment for agricultural water use should be increased.
