Abstract
鉴于二类水体本身光学性质的复杂性及其与人类生产活动的密切关系,利用遥感数据监测二类水体水质受到了国内外学者的普遍关注,成为海洋学领域的热点问题。悬浮泥沙含量是表征水质优劣的一个重要参数,众多研究致力于建立悬浮泥沙反演模型的研究,定量反演二类水体悬浮泥沙浓度。该文总结了近年来二类水体悬浮泥沙遥感反演算法的研究进展。悬浮泥沙定量反演模型大致可分为以下三类:1)利用水体光学特性和水体组分之间关系建立的经验模型; 2)综合经验模型和物理模型构建的半分析模型; 3)基于辐射传输模型和生物光学模型建立的物理模型。针对目前反演算法存在的主要问题,提出未来的研究需加强反射率光谱曲线研究、开发高光谱遥感数据以及综合多源数据信息等方面的内容。
