| 摘 要： | 以福建九龙江口地区为研究区域,利用2008年和2012年的国产环境一号(HJ-1)CCD数据,综合利用监督分类、非监督分类和知识规则相结合的方法对湿地进行分类和专题提取。结果表明:与2008年相比,2012年九龙江口湿地总面积有所减少。天然湿地中河流的面积减少,主要转为滩涂、红树林和其他。养殖场的面积增加最多,主要由农田、河流和其他转化而来;而农田的面积减少最多,主要转为养殖场、林地和其他。快速城市化对九龙江口的湿地影响很大。

| Abstract: | The Jiulong river estuary wetlands in Fujian province were studied to classify wetlands and identification of specific categories by combining supervised classification, unsupervised classification and knowledge of the rules based on the remote sensing data of HJ-1 CCD acquired in 2008 and 2012. Results indicated a slight reduction of wetland area in 2012 compared to 2008. The reduction of river area in natural wetland was mainly caused by shifting to tidal zone, mangrove forest and others. The total area of aquatic farms increased most, mainly shifting from farmlands, rivers and others. However, the area of farmlands decreased most, mainly shifted to animal or fish farming land, forest land and others. Rapid urbanization has produced a great impact on Jiulong river estuary wetlands. |
