森林湿地是湿地的重要组成部分，因其群落结构复杂，从景观尺度上对其进行识别是湿地研究的难点之一。在分析国内外相关科学文献的基础上，从地理生态环境、影像特征及影像信息处理单元角度分析了森林湿地遥感信息提取方法的研究现状，总结了当前森林湿地遥感提取的特点，并在此基础上初步预测未来森林湿地遥感信息提取方法的发展趋势。结果表明：以水文特征反演为依据，认为基于地理生态环境的提取方法包括基于水文地貌学方法、基于光学遥感和微波遥感的分类方法；基于影像特征提取方法包括基于雷达散射特征决策树、随机森林决策树及航片目视解译法；基于影像信息处理单元角度方法主要有基于像元和对象分类2种方法。

Forested wetland is an important type of wetlands. Because of its complex community structure, mapping forested wetland becomes one of challenging issues in wetland research. In this paper, research conclusions published in relevant literatures were analyzed, and then a review of methods for mapping forested wetlands was made from the angles of geographical biological environment, images characteristics and images mapping units. In addition, the basic features of different mapping methods of forested wetlands by remote sensing were presented, and some possible trends of future research were preliminarily predicted. According to understory hydrological inversion, the mapping methods based on geographical biological environment mainly include the hydrogeomorphy-based method and the optical and microwave remote sensing -based classification method, whereas methods based on features of images include decision tree based on radar statistical backscatter characteristics, random forest decision tree and aerial photograph interpretation, which provide data and technical supports for tapping comparing and assessing information, thus conducive to further development of mapping methods. From the angle of imagery interpretation units, the forested wetland mapping methods have undergone the development from per - pixel classification to object-oriented classification.
