Description :
Soil types and soil distribution pattern changes were assessed and compared by using two soil maps made in 1987 and 2006. During the period from 1987 to 2006, there were widespread changes in spatial distribution of soil types in Manasi River Basin at class-level : the fragmentation decreases because of the decrease of patches numbers; many equirotal soil patches were formed and various soil types dominated the soil landscape during the recent 20 years. Changes of different soil types are one of major indictors to show environment changes and impacts of human activities. Therefore, it is necessary to emphasize the study of soil type changes in the arid and semiarid region.
