摘要：
With the background of global change, wetland has great sensitivity and vulnerability. In order to investigate the spatial characteristics and heterogeneity in the pattern and dynamic of natural and constructed wetlands, the wetland ecosystem pattern in 1990, 2000, 2013 were rebuild based on satellite images from Landsat TM, ETM+, and OLI. Results indicated that wetland area for Northeast China in 1990, 2000, and 2013 was observed to be 117.5, 105.7, and 104.1 thousand square kilometers, respectively. Most of the disappeared wetlands were converted to cropland. Based on the changing trends of wetland, climate, and human factors, human activities were the leading driving forces for the losses of wetland.
