英文摘要 | Wetlands are special ecosystem lying between the terrestrial and open-water areas. Similar to forest, grass, and ocean ecosystems, wetlands take parts in protecting environments and exploring resources. In China, wetlands are undergoing significant degradation that is caused by both natural processes and human activities. In order to know the details of wetlands change so as to take suitable actions to protect wetlands, Landsat TM/ETM images are used as main data sets. Accessorial data such as topography map and China mire map are also used. In this paper, wetlands are defined as swamplands, potholes, wet meadow, riverine, lacurtrine. Three periods (1990a, 1995a, 2000a) data of wetlands in china are extracted from TM through the interactive interpretation. Applying spatial analysis function of GIS technology and statistics methods, the spatial distribution pattern and temporal changes are studied. The research results show that, during the 10 years from 1990 to 2000, wetlands area decreased largely, and spatial difference is notable. Finally, the driving forces resulting in mires changes are analyzed. |
