摘　　要：为了研究区域地下水的变化规律,结合沧州1989～2007年72眼观测井的水位、区域开采量和补给量等资料,研制了该区域承压水漏斗水位的BP网络模型。该模型具有分布参数模型的特征,对水位拟合与检验的合格率均大于70%,符合相关规程要求。应用所建模型,对5个不同开采与补给方案下,研究区未来10 a承压水漏斗的动态变化进行了模拟,模拟结果合理、可靠。In order to study the variation laws of regional underground water, a BP network model for studying the water level of confined water funnel in the region is established, combining the data of the 72 observed wells, including exploitation quantity, recharge rate in Cangzhou from 1989 to 2007. The model possesses the characteristics of a distributed parameter model. The re- suits indicate that, both the qualified rates of fitting and test are higher than 70% , which accords with the requirements of relative codes. By the model, the dynamic variation laws of the confined water funnel under 5 different exploitation and recharging plans in the research area in the next 10 years are simulated, and the simulated results are rational and reliable.
