摘要
大小柴旦盆地地下水资源丰富,境内的塔塔棱河补给了该盆地地下水,针对大小柴旦盆地平原区水文地质条件,建立地下水流数学模型,选用Processing Modflow集成系统对大小柴旦平原区极富水地段进行地下水数值模拟研究,并按设计开采量5.0×104m3/d对地下水水位进行预报,大小柴旦盆地分水比例得到明确,经模型验证预报结果可靠,水源地设计开采量是有保证的,下游水环境和生态环境在可接受范围内。
Qaidam Basins have abundant groundwater resource which is mainly recharged by Tata Leng River. A mathematical model for groundwater flow is built on the hydrogeological conditions of the plain area in basin aiming to have a discussion of groundwater numerical simulation on extremely rich water areas. Qaidam Basins will get a clearly water segrating proportion by forecasting the groundwater level with a design exploitation of 50,000 m3/d.Through the model validation,it turns out that the prediction results are reliable,and its design exploitation of water source is guaranteed. The water environment and ecological environment in down-streams is within an acceptable range.
