| 格尔木河冲洪积扇区有着巨厚的第四系砂卵砾石层,形成了良好的储水空间,研究其含水层系统特征、地下水循环演化及资源开采潜力对水资源合理开发利用具有重要指导意义。本文基于地质调查、水文地质钻探、动态长观等资料,将含水层系统进行了划分,并对地下水的循环演化进行了阐述。运用补给量总和法、排泄量总和法以及断面径流量法对研究区地下水天然资源量和开采潜力进行了计算。结果表明:研究区河水与地下水经历三次转换,主要模式分为:中高山区模式、冲洪积扇区模式、冲湖积平原区模式；含水层系统可分为:局部循环系统、中间循环系统和区域循环系统三个子系统。研究区地下水天然资源量为206.75×104 m3/d,开采潜力达103.38×104 m3/d,可为下游的盐湖产业基地提供水源保障。 |
| 英文摘要: |
| The alluvial sector of Golmud River has a huge thick quaternary sand, pebble and gravel layer, which forms a good water storage space. The study of its aquifer system characteristics, groundwater circulation evolution and resource exploitation potential are of great guiding significance for the rational development and utilization of water resources. Based on geological survey, hydrogeological drilling and dynamic long observation, etc., the hydroquifer system is divided, and then the cyclic evolution of groundwater is expounded. The natural resources and exploitation potential of groundwater in the study area are calculated by using the recharge sum method, the discharge sum method and the section runoff method. The results show that river water and groundwater in the study area undergo three transformations. main modes are medium and high mountain area, alluvial plain area; aquifer system can be divided into three subsystems:local circulation system, intermediate circulation system and regional circulation system. The natural groundwater resource in the study area is 206.75×104 m3/d, and the exploitation potential reaches 103.38×104 m3/d, which can provide water source guarantee for the downstream salt lake industrial base. |
