%X By using landscape analyzing software Fragstats 3.3 and the interpretation results of remote-sensing images of 1960,1975,1987,1995,2000 and 2005,this paper analyzed the dynamic changes of landscape pattern during the desertification in Duolun County of Inner Mongolia in 1960-2005.The results showed that in 1960-1995,the desertification area appeared a tendency of increasing first and decreasing then,with a total increase of 212.7 km2.The numbers of desertification landscape patches decreased after an initial increase,landscape diversity and evenness increased,and the shapes of light-,moderate-,and heavy desertification patches tended to be simplex.From 1995 to 2005,the numbers of desertification patches increased greatly,landscape diversity and evenness decreased,and the shapes of light-,moderate-,and heavy desertification patches tended to be complex.Since 1960,the shapes of severe desertification patches had been inclined to complication.In the study period,the whole desertification landscape showed a trend of integrity-broken-integrity-broken,and the broken degree of the patch types of desertification landscape was gradually from light down to severe.
