摘要:
外界环境条件以及自身因素的驱动,改变了传统湖泊水色遥感垂向均一的理论假设前提,基于垂向非均匀条件的湖泊水体水色参数的遥感称之为非传统湖泊水色遥感.本文分析了传统水色遥感面临的挑战,且非传统湖泊水色遥感中藻类叶绿素a浓度的垂向分布类型及其定量表达、水下光场分布的定量表达模型与数值模拟方法,给出垂向异质水体遥感反射比的定量表达式,分析了藻类垂向异质对水色参数遥感反演模型的影响,最后提出下一步需要重点关注的问题.

The status and development of the non-traditional lake water color remote sensing

Abstract:
We define "non-traditional water color remote sensing" as the study of the heterogeneous vertical distribution of water color parameters and their inherent optical properties, in relation to the environmental factors (external and internal) that influence their distribution.This is quite different from traditional water color remote sensing as it includes the third dimension, rather than assuming homogeneous vertical distribution of water color parameters.In this study, we explore approaches to determine the vertical distribution of chlorophyll-a and explore methods to simulate the underwater light field.It should be noted that remote sensing reflectance (Rrs) of non-uniform water column could be equivalent to optically weighted Rrs with vertical uniform distribution.The effects of non-uniform vertical profiles of chlorophyll-a concentration on inversion models of remote-sensing is explored, and challenges should be the focus of further research.
