optimum size of analysis windows of relief,which is 5km×5km
is defined by means of windows analysis and sample statistical method. Relief in soil erosion of China has been extraded using ARC/INFO software and mapp
d using Arcview.Applicalality of relief was analyzed and initially application of reli
f factor in assessment of Chinese potential soil and water loss is studied.
