石家庄市地下水系统的数值模拟与预测

Numerical Simulation and Prediction of Groundwater System in Shijiazhuang

本文应用GMS软件,建立石家庄市地下水流模型。应用该模型,预测黄壁庄水库的渗漏补给减少后,石家庄市地下水系统的变化情况,根据模拟结果得出,随着黄壁庄水库侧向渗漏量的减少,石家庄市地下水位不断下降,地下水降落漏斗面积不断扩大。因此提出从水库直接取水灌溉、加大污水回用力度、尽快实施南水北调等措施,以保证石家庄市地下水资源可持续发展,对于指导合理利用地下水、缓解地下水位下降具有现实意义。

The GMS software is applied to set up the groundwater model of Shijiazhuang city. After appling the model, the variable condition of the groundwater system is predicted. According to the simulated result, it is known that the groundwater level decreases and the funnel＇s area increases with the decrease of lateral leakage from Huangbizhuang reservoir. Therefore, it is suggested that we should utilize water from reservoir to irrigate, increase the extent to recycle the seepage and carry out the project of supplying water from south to order to guarantee the water resource＇s sustaining utilization of Shijiazhuang city. Such suggestionsare north, in useful to guide the groundwater utilization reasonably and alleviate the decrease the groundwater level.
