摘要: 利用多年地下水水位资料,较系统地分析了地下水水位动态变化规律,建立了基于BP网络的地下水水位预测模型,预测结果表明地下水水位将持续下降,承压水下降速率远大于潜水的下降速率。

Abstract: Based on formation of groundwater and its affecting factors and consideration of the hydrogeological conditions,groundwater regime types in the study area are examined.The groundwater regime of the phreatic aquifer mainly belongs to subsurface runoff and exploration type,infiltration-subsurface runoff and exploration type,while the groundwater regime of the confined aquifer is of subsurface runoff and exploration type.On the basis of analyses of groundwater levels,a groundwater level dynamic trend model is established with BP network,and the characteristics of groundwater level change and the expansion trend of the depression cone of are predicted.
