地下水动态预测的探讨

简要介绍地下水数学模型的原理和应用实例,着重介绍在河北省大清河地下水系统的大沙河-磁河冲洪积扇孔隙地下水区,尝试建立地下水埋深变幅预测的统计相关方法和神经网络模型取得的良好效果;同时对地下水预测中的降水补给、边界和初始条件等的处理进行讨论,对数学模型和统计相关模型优缺点进行比较。

Preliminary Study on Groundwater Level Prediction

This paper briefly introduced the groundwater conception model and its application, and emphatically introduced the es-tablishment of correlation models and neutral network models for groundwater level prediction in alluvial fan porewater aquifer ofdashahe-cihe region at Daqinghe groundwater aquifer system in Hebei Province. Isues such as replenishment of precipitation forground water,mining yield of groundwater, boundary condition and initialization condition in groundwater prediction were discussed.Advantage and disadvantage of conception model and correlation model were also compared.
