河西走廊地下水资源

Groundwater Resources in Hexi Corridor

本文利用已有的水文地质资料 ,广泛收集、系统整理了河西走廊地区内最新的水资源利用、水利化现状、勘探实验及水文气象资料 ,在此基础上采用基流分割法、径流模数法、大气降水入渗法、和水均衡法对河西走廊不同区段的地下水天然资源量进行了最新的计算评价。经计算 1 999年河西走廊地下水资源总量为 5 5 8395 .5 5万 m3 /a,其中祁连山 -阿尔金山2 3840 0万 m3 /a,走廊区 2 4 670 2 .74万 m3 /a(已扣除重复量 ) ,北山 -阿拉善中低山区 (包括腾格里、巴丹吉林沙漠 ) 732 92 .81万 m3 /a。

Based on the meteorological data, hydrological data, and the hydrogeological data, and considered the status quo of water resources utilization and hydrologic engineering, the natural groundwater resources in different zone of the Hexi Corridor was evaluated by the hydrograph segmentation method, the runoff coefficient method, the precipitation infiltration method and the water budgets method. The results showed that the total groundwater resources in Hexi Corridor is 558395.55×10 4m 3/a in 1999:238400.00×10 4m 3/a in the Qilian mountains and the A'erjin mountains , 246702.74×10 4m 3/a (deductedthe repeated water and the repetition water between the mountain area and basin area)in the corridor basin, and 73292.81×10 4m 3/a in the Beishan mountains and the medial-lower Alashan mountains including parts of the Tenggeli desert and Badanjiling desert in study area.
