In order to study the transformation law of wetland in western Jilin and analyze the impact of eco-geological environment factors on the evolution of wetland, a representative region of western Jilin is selected and the two-stage wetland data revealed by CBERS-2 and Landsat-8 OL are used. Through the geo-information atlas, combining with intensive infographic of wetland distribution and the distribution status and variation trend of quantified relative change rate, elevation, climate and population data, the relationship between wetland dynamic change and environment is studied. The results show that paddy fields cover the largest area in study area in 2007 and the distribution density of wetlands on the north side of the study area is generally high. The total wetland area shows an increasing trend, the Neotectonic movement controls wetland development and precipitation becomes the main factor which affected wetland changes in the past 10 years.
