| 摘 要： | 【研究目的】格尔木市地处柴达木盆地南缘,是青藏高原上正在崛起的新兴城市,随着各个工业园区的建设及中国最大的钾肥生产基地的建成,地下水资源的重要作用更加凸显,查明其地下水资源量对工矿企业及钾肥生产基地的运行至关重要。【研究方法】基于资料收集、动态长观、钻孔抽水试验等手段,采用补给量总和法以及排泄量总和法结合数值模拟等方法,评价了区域地下水天然资源量及允许开采量。【研究结果】格尔木河冲洪积扇地下水天然资源量为199.8×104 m3/d,允许开采量为100×104 m3/d。【结论】格尔木地区存在百万吨级的地下水源,6座水源（已建/在建/规划）规划开采量达百万吨时,地下水有充足的补给保证,可持续稳定开采。最终提交了B+C级地下水储量100×104 m3/d的百万吨级地下水源。创新点：基于最新一次的地下水详查工作,完善了区域地下水流模型;在设定模型入境水量场景时,采用“丰枯年组合”的方法,充分考验了含水层的调节能力和连枯年持续供水能力,评价的结果可信度高。

| Abstract: | This peper is the result of hydrogeological survey engineering.Objective] Golmud is a rising city on the Qinghai- Tibet Plateau located on the southern edge of the Qaidam Basin. With the construction of various industrial parks and the establishment of the largest potash production base in China, the important role of groundwater resources has become more prominent. For the operation of industrial and mining enterprises and potash production bases, it is very important to find out the amount of underground water resources.Methods] Based on data collection, dynamic long view, borehole pumping test, etc., the regional groundwater natural resources and allowable exploitation were evaluated by using the recharge sum method, section runoff method, excretion sum method and combined numerical simulation method, etc.Results] The amount of groundwater natural resources in the alluvial fan of Golmud River is 199.8×104 m3/d, and the allowable exploitation amount is 100×104 m3/d.Conclusion] Millions of tons of underground water sources exist in Golmud area. To ensure an adequate recharge of groundwater, the condition for sustainable and stable exploitation is that the planned exploitation of six water sources (built/under construction/planning) reaches one million tons. Finally, a million- ton groundwater source with B + C groundwater reserves of 100×104m3/d is submitted.Highlights: The regional groundwater flow model has been improved based on the latest detailed survey of groundwater; The method of "drought and rainy years" is used to set the inflow volume scene of the model, the regulation capacity of aquifers and the ability of continuous water supply in dry years have been fully tested, and the evaluation results have high credibility. |
