遥感技术在红树林湿地研究中的应用述评

红树林为自然分布于热带和亚热带海岸潮间带的木本植物群落,是淤泥质海滩上特有的植被类型,也是重要的海岸湿地资源,作为独特的海陆边缘生态系统在维持海岸生态平衡中起着特殊的作用.遥感技术的发展为红树林湿地研究提供了新的方法和强有力的技术支持.文章论述了遥感技术在红树林生态监测中的应用,包括遥感数据源的选择.红树林湿地区域研究、类内区分和类外区分以及红树林湿地遥感分类方法,精度对比情况以及遥感技术在红树林湿地动态变化与管理中的应用.指出目前存在的红树林湿地原始影像数据的选取、遥感分类精度以及红树林湿地遥感分类方法选择等问题.提出了未来发展动向.

Comment on Application of Remote Sensing Technology to the Study of mangrove Wetland

mangrove naturally distribute in tropical and sub-tropical wet seashore belt,is a woody plant community and a peculiar plant type in silt beach as well as a significant seashore wetland resource.Thus it plays particular role in maintaining seashore ecological equilibrium.The development of remote sensing provides a new approach and powerful technique supports for the study of mangrove wetland.The paper elaborates this application to ecological monitoring of mangrove.It points out the issues in the study including selection of primitive image data,classification precision of remote sensing and selection for remote sensing classification methods of mangrove wetland.In addition,it proposes a direction toward its development in the future.
