7.3) Soil physical factor is strongly impacted total nitrogen and total phosphorus in surfacerunoff, the factor of withers and falls influence total phosphorus in surfacerunoff is remark- able;
9.The VIC model combined with a new surfacerunoff parameterization, which takes into account the effects of soil heterogeneity on Horton and Dunne runoff, is applied to runoff simulation over the mainland area of China.
