- Abstract:
-
Taking the Zhifang gully small watershed as an example, this paper is to further deeply study the basic regulations and characteristics on runoff and silt in some small watersheds in Loess plateau area on the basis of observed data of 50 years of precipitation, runoff and silt as well as research achievement, by ways of d-base establishment, analysis, calculation, partly comparing and related analysis. Through the analysis, we studied the basic characteristics and change regulation and their relationships between precipitation, runoff and silt, meanwhile, we established a single factor mathematic model between quantity of soil loss and its affected factors, which can be used as simple evaluation to analyze runoff and silt and quantity of soil loss in similar areas. This paper gives the affected degree of soil loss reduction by main affected factors and their changes as well as the single factor mathematic mode between quantity of soil loss and its main affected factors.
