Research on Mangrove Canopy Spectral Reflectance Characteristics & The Classification of MangroveSpecies by Remote Sensing

Abstract

遥感技术是近年来发展起来的对红树林生态监测的关键技术。本文以福建九龙江口红树林的自然保护区部分地区为研究区域,探讨了利用遥感技术进行红树植被分类的流程和方法。在总结归纳了红树林生态监测中的卫星遥感技术方法后,针对红树植被遥感分类方法普遍存在对图像要求较高而分类精度差等问题,首先进行大量野外实地调查和严格的实测光谱分析,探讨基于SPOT-5和LandsatTM卫星遥感影像融合,并借助全球定位系统(GPS)定位仪实地定位精确选择训练区,同时通过研究不同红树植物种类光谱间波段特征差异,构造新的波段变量,采用多步骤分类方法,对研究区域的3种红树林植物种类进行图像分类。 主要研究内容如下: (1)以...The remote sense is the key technique for the mangrove zoology monitoring. The widely accepted remote sensing method for classification of mangrove usually requires high quality images, and a training area which is difficult to find. This study particularly recites the application development of remote sensing in mangrove environment search, then this study aims to develop a more applicable method...学位:工学硕士院系专业:海洋与环境学院环境科学与工程系_环境工程学号:20033404
