投影寻踪回归在紫坪埔洪水预报中的应用

Application of Projection Pursuit Regression in Forecasting ZiPingpu's flood

针对现有紫坪埔洪水预报模型或不能充分挖掘样本信息或不便于实际应用的问题 ,现用投影寻踪回归方法建立了紫坪埔洪水预报模型 ,分别对洪峰和洪水过程进行了预报 ,并与其他方法进行了对比 ,取得了满意的效果 。

Some of the present models of forecasting ZiPingpu's flood can′t fully discover the information in flood process and others are impractical.So a staistical method,projection pursuit regression is applied in forecasting peak flood and flood process.Comparing with other models,the new one gets high precision and is easy to be operated in practice.
