Based on the TM/ETM + remote sensing data of Wuliangsuhai wetland in 2003-2011, the methods of ratio vegetation index and bond combination was used to obtain the information about the areas of open water, water plants, reed and farmland in Wuliangsuhai wetland and the change of area and their patterns were analyzed. By using the method of data point’s average absolute deviations, the change rates of above-mentioned areas were calculated and the changing trend was estimated. Based on these comparison and analysis, the dynamics change of Wuliangsuhai wetland was predicated and the results are as follows: the change rate of open water is 26.56%, and that of water plants and reed are -20.66% and -1.49% respectively, i.e. the area of open water will increase by 33.57 km2,while the areas of water plants and reed will decrease by 21.02 km2 and 4.92 km2 respectively in 2012.
