| 摘 要： | 利用陕南长江水系丹江荆紫关等6个流域降雨、径流和输沙的实测资料，用多种函数形式模拟其相互关系，选择出最优的模拟函数，提供了由降雨变化预测年径流和年输沙变化趋势的一种途径。井通过对汉江上游沮水河等15条支流8个影响输沙因子的分析优选，建立了以年雨量、植被盖度、治理程度及河网密度4个因子表示的河流输沙经验模型。

| Abstract: | Based on field data of rainfall, runoff and sediment discharge from six tributaries of the Yangtze River in south Shaanxi Province, several functions are used to describe the relationship among them. Finally an optimized model is established. It can be used to predict the trend of the annual runoff and the annual sediment yield.Besides, by analyzing and optimizing eight factors influencing the sediment transort, an empirical model consisting of four factors, such as annual runoff, vegetation covering rate, harnessment degree and branch density, is established.\= |
