摘　　要：红树林是海岸带生态系统中重要的植物群落,具有较高的社会、生态和经济价值。遥感技术的发展为红树林监测提供了一种高效便利的手段。雷达遥感由于具有穿透性好、不受云雨影响的特点,在红树林分布地区具有得天独厚的优势。对近几十年来雷达遥感在红树林监测方面的研究进行了回顾,着重分析了红树林散射机制、红树林分类与识别和红树林生物物理参数反演这3个方面的研究进展,对各类方法进行了总结和对比,最后针对存在的问题提出了未来可以改进的方向。Mangroves are important plant communities in coastal ecosystems,and have enormous social,eco⁃logical and economic values.The development of remote sensing technology provides an efficient and conve⁃nient way for mangrove monitoring.Radar remote sensing has a unique advantage in mangrove distribution area because it has high penetration and is unaffected by cloud and rain.This paper reviews the study on mangrove monitoring based on radar remote sensing in recent decades in the aspects of mangrove scattering mechanism,mangrove classification and recognition,and mangrove biophysical parameters retrieval.The summary and com⁃parison of different methods in three aspects are also proposed.Finally,the future improvements are discussed according to the existing problems.
