| 摘 要： | 通过分析黄土高原淤地坝淤积量与相应次侵蚀性降雨指标的关系，提出了基于投影寻踪回归分析的淤地坝泥沙淤积量预测模型，利用实测资料对淤地坝泥沙淤积量进行预测。结果表明，该模型具有较高的拟合度和预测精度。

| Abstract: | The relationship between sedimentation amount of warping dam and the corresponding erosive rainfall indexes in loess plateau was analyzed.And then the prediction model on sand sedimentation amount of warping dam based on projection pursuit regression analysis was proposed,and the sand sedimentation amount of warping dam was predicted with the relevant measured data.The results showed that the model had high fitting degree and prediction accuracy. |
