小流域水沙调控正态整体模型模拟实验

Simulated Experiment on Normal Integral Model of Water Regulating and Sediment Controlling for Small Watershed

在小流域正态整体模型上，分期配置水土保持措施，采用人工降雨方法，研究水沙变化规律。结果表明，流域产水产沙与水土流失的治理程度呈对数关系。文中还探讨了模型比例尺选择、模型制作和下垫面模拟技术等问题。

A normal integral medel of small watershed which was disposed with different measures ofsoil and water conservation at different tinies,and aimulated rainfall method were employed in thisstudy,the study aims to investigate the varying patterns of water and sediment. The results indicatethat the sediment yield, runoff correlates with the degree of soil erosion controlling in logarithmicforms. The selection of model scale ,model building and the simulated techniques of land surface fea-tures are probed and discussed in this paper.
