After extraction of the vegetation cover and the change in Dagou River Basin during 1999-2009 ac-cording to the remote sensing technology , the conversion analysis of the 7 types of vegetation is completed inclu-ding cultivated land, hamada, burns, weeds, bringing, thickets, dense thickets and forest land.By redefini-tions of the rocky desertification and greening , the whole area was divided into mid , moderate and severe de-grees.The analysis of 7 types of vegetation suggests that the desertification rate is slightly higher than greening . In 10 years of mutual transformation , rocky desertification and greening area are 30.83% and 30.55%. The moderate and slight rocky desertification areas account to about 8.60% and 30.83%, slightly larger than the moderate and greening of 6.85% and 30.55%.
