摘要
通过对渭河20多条支流建立的回归模型及分析,获得了回归方程系数b与河流流域产流能力的关系;回归方程的常数项a与基流估算的关系;以及流域临界降水量与流域水土流失程度的估算.
The thesis analyzes regressive model of branches of wei River, gains the relation between regress equational ratio and the basin capacity, the fixed quantity “a”of regressive equation and estimation of basic branch, rainfall within threshold and soil erosion.
