| 摘 要： | 如何利用遥感技术获取高精度的湿地信息是湿地遥感研究中的重要内容之一.基于高空间分辨率的遥感影像数据,研究利用面向对象的分类方法,综合利用遥感数据的光谱信息、纹理特征、拓扑关系等信息进行多尺度分割,通过对对象的目视解译建立隶属度函数,并结合最邻近分类法,获取湿地信息.并以福建省闽江口湿地为例,采用高分辨率的SPOT5影像数据,研究表明：利用面向对象的方法对SPOT5遥感影像进行湿地信息的提取精度达到90.40%,为湿地信息的提取又提供了一个有效的方法.

| Abstract: | How to use remote sensing technology to obtain accurate information of wetlands is one of the important contents of remote sensing research for wetlands. Research using the object-oriented classification, comprehensive utilization the information of remote sensing data, such as spectrum, texture, topological information for multi-scale segmentation, established membership functions based on visual interpretation for object ,obtained information of wetlands based on high spatial resolution remote sensing image. And used spot5 image data by the specific exam- ple of Minjiang River Estuary wetlands in FuJian province, the studies showed ： the accuracy of information extraction method in object-oriented based on high-resolution remote sensing image approach to 90.40%, which provide an effective method to extract wetlands information. |
