摘要

以1986 年和2000 年遥感影像为基本信息源，在GIS 技术支持下,建立湿地空间数据库，分析15 a来研究区湿地资源的时空变

化特征及驱动力。结果表明，水稻田和虾蟹池面积大量增加，空间分布趋于集中化；沼泽地和滩涂面积不断萎缩，面积大减，破碎

化程度日益严重；人口压力、传统工农业生产和经营方式及人们对经济利益追求是湿地资源变化的重要原因。

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.
