Abstract:
The runoff and rainfall data of typical forested and non-forested watersheds in Ziwuling region, which is located in the hinterland of the Loess Plateau, were used to analyze their annual runoff variation comparatively. The result showed that the annual distribution of runoff in forested watersheds was uniform, compared with that in non-forested watersheds. The total runoff in flood season decreased by 8.88 mm and 7.1 mm. Regression analyses between runoff in dried-up season and rainfall in flood season or in dried-up season showed that the rainfall in flood season in forested watersheds could be changed into underground runoff by forest vegetation, and increased the runoff in dried-up season. The annual variation of runoff also indicated that the total effect of forest vegetation on dried-up runoff complement from October to December was 1.69 mm and 0.5 mm, and that from January to May was not significant.
