摘要
为合理确定地下水调控方案,采用BP算法,研究了宝鸡市区地下水位动态变化过程,建立了地下水位动态变化预测模型,通过对1990-2005年地下水数据的训练,预测了未来3 a的地下水变化情况,结果表明预测结果与实测结果非常吻合,说明BP模型能较好地预测宝鸡市区地下水位动态变化;依据此模型,结合宝鸡市水资源开发利用现状及未来水利工程建设规划,提出了宝鸡市区未来不同水平年地下水调控方案与合理开发利用宝鸡市区地下水资源的建议。
To ascertain the regulation schemes of groundwater reasonably,using BP algorithm,this paper studied the changing process of groundwater regime of urban area of Baoji city,established the prediction model of groundwater regime and predicted the changes of groundwater of the future 3 years after training the groundwater data of the years from 2000 to 2005.The results showed that the prediction coincided with the practical one,which showed that the BP model could be used to predict the groundwater level of urban area of Baoji city.Based on the model,combined with the present situation of water resources development and use of urban area of Baoji and the program of hydraulic project construction in the future,this paper put up the groundwater regulation schemes of different future level years and the reasonable suggestions of the development and use of groundwater resources of urban area of Baoji city.
