| Abstract: | Using 1986 and 2000 remote sensing data as the basic information resource and with the support of GIS,the authors built up a wetland spatial information dataset. On such a basis, the changes of wetland resources in this area were analyzed, and the reason for such changes was investigated. The area of farmland as well as shrimp and crab pools increased rapidly while that of swamp and shoal land decreased significantly in 15 years. The changes of wetland in this area were closely related to climate fluctuation, rapid growth of population and development of industry and agriculture, with the social -economic factors being most important. |
