In order to study dynamic change characteristics of swamps in Zioge plateau area composed of Zioge County, Maqu County and Hongyuan County, the authors made use of the remote sensing data and the Geographical Information System technology and introduced four characteristic parameters such as the degree of dynamic change to get the numerical values of these characteristics. The results show that there has been a remarkably decreasing trend of swamp area in the past 30 years, though the decreasing speed has somewhat slowed down in recent years, and that the fragmentation of swamp landscape has been evident in this area. Furthermore, there exists a temporal-spatial pattern in the swamp degradation of this area.
