The characteristics of the wetlands evolution process and the main driving force in Tarim Basin and Junggar Basin were comparatively studied based on MSS(1975),ETM(2000) and CBERS02(2007) remote sensing data. Some conclusions have been reached: ① The wetlands area of Juggar Basin increased by 254.94 km2, but that of Tarim Basin decreased by more than 2 739.88 km2 from 1975 to 2007. The rapid degradation of swamp wetlands in Tarim Basin was the major factors which caused the reduction of the wetlands. ② The Shannon-weaver index, the Evenness indexes and the species diversity of wetlands were reduced and the dominant wetlands types changed from swamp wetlands into river wetlands in Tarim Basin from 1975 to 2007, and the evolution of the wetlands in Tarim Basin could be divided into two steps: landscape fragmentation and extinction. In contrast, the Shannon-weaver and the Evenness indexes of wetlands in Junggar Basin sustainably increased, but the Evenness index continuously decreased. The wetlands scenery structure of Junggar Basin became rationalized. ③ The precipitation and temperature of Tarim Basin increased by 0.59 mm/a and 0.042 ℃/a in the past 32 years, whereas the corresponding values were 1.69 mm/a and 0.047 ℃/a in Junggar Basin. The wetlands evolution process of Junggar Basin was closely related to climate change .④ During 1975-2000 and 2000-2007, the areas that converted from wetlands to farmlands were 1 035.06 km2 and 1 030.30 km2 respectively, and the percentages of the reduced area were 81.74% and 69.92%. Respectively therefore, human activities seemed to be the main driving force which caused wetlands degradation in Tarim Basin.
