Abstract

This paper, taking the Yangou Basin as a case study and using day-by-day meteorological data of Yan’an station in 2005, simulated and analyzed the quantitative relation between crop yield, soil and water loss and topographic condition with the aid of WIN-YIELD software. Results and discussion about the influence of topographic gradient on crop yield, and on soil and water loss. It is showed that topographic gradients of 5° and 15° are two important thresholds
