| Abstract: | Four phases of wetland thematic maps in 1980, 1990, 2000 and 2007 were mapped, by using Landsat MSS/TM/ETM+ remote sensing images. The processes of wetland landscape pattern changes and the regional climate changes and human activities impact were analyzed. The results shown that, during the period of 1980 to 2007, the natural wetlands decreased from 5360 km2 to 4331 km2, and man-made artificial wetland increased from 3492 km2 to 4499 km2. In 1980, the river wetlands are widely distributed. And then, it is decreased with agricultural wetlands, reservoirs, marine aquaculture field and brine pan, and shallow water wetlands increased. Influenced by climate change and human activities, the wetland landscape patches are becoming fragmentation, and their spatial distribution is becoming homogenization and isolation. Temperature is the main natural factors to influence the wetland changes. Total population change and food production are the main human activities factors. Overall, for the watershed landscape pattern changes, the influences from human activities are greater than that of natural factors. |
