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3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 rainfall and sediment discharge de-creased in Shahe basin. Water production and sediment yield in the basin can be divided into 3 different periods. With prin-ciple of water balance and the mechanism for sediment yield,combining implementing situation of water-soil conservationproject,the BP artificial neural network established to analyzing the influence degree of runoff and sediment at differentstages by related factors.
