The information of multi-source remote sensing images of Wuliangsuhai wetland at different time and space granularity from 1986 to 2008, which lies in the semi-desert area, was obtained by GIS and RS technology combined with the theories and methods of landscape ecology. The dynamics of landscape patch index for different types of areas was described and the spatial-temporal heterogeneity of wetland ecological resources was analyzed. Evolutionary relationship and direction among various wetland types of Wuliangsuhai were researched. The dynamic evolution trends of various types of wetland landscape were analyzed. The results showed that the degree of landscape fragmentation was reduced, the water district was lost, and underwater plants were tufted. The average area of reed-based large hyper-surface plants was above 49% of wetland, which was the dominant evolution type of the lake wetland. Evolution of spatial and temporal patterns of wetlands was related to climate, water conditions and artificial impact, which reflected the process and intensity of human disturbance on wetland landscape.
