摘要
通过分析沙河水平口实测水文资料,得出沙河流域径流量、输沙量整体呈减小趋势。将流域产水、产沙分为三个不同时段,根据水量平衡原理及产沙机制,在分析影响沙河水沙变化几个主要因素的基础上,建立BP人工网络模型分析相关因素对径流、泥沙在不同时期的影响程度。
Through analyzing hydrologic data observed at Shuipingkou station, the results of the rainfall and sediment discharge decreased in Sha he basin were gotten. Water production and sediment yield in the basin could be divided into 3 different periods. With principle of water balance and the mechanism for sediment yield,combining implementing situation of water-soil conservation project, the BP artificial neural network had established to analyze the influence degree of runoff and sediment at different stages by related factors.
