In Loess Plateau,soil erosion is very intensive,and the actual productivity is low.To study the region s crop yield potential can offer grounds for increasing crop yield and conducting agricultural production programming.This paper introduces the characteristics,component,and application procedure of EPIC,and revises some crop parameters.Taking the maize and wheat as example,we proved that there is a good adaptability for EPIC model to be used in Loess Plateau for crop productivity simulation research.The...
