关于沿海沃茨悬浮沉积物浓度的资料对于了解和管理沿海环境是必要的。传统上，悬浮泥沙浓度（SSC）的测量一直是耗时和昂贵的船调查，允许在空间和时间的单点准确测量SSC。空中和空间传感器的遥感已证明是这类调查的一个有用的辅助手段，因为它提供了否则无法获得的沉积物的瞬时和综合情况。遥感在这方面取得成功的关键是SSC与遥感光谱辐射率（L（x））之间存在着强的正相关关系。本文介绍了SSC/L（x）的关系，探讨其物理基础，在一系列环境条件下的鲁棒性及其作为估计工具的实用性。未来的研究应集中在抑制环境影响和最佳采样的SSC。
Information on the concentration of suspended sediments in coastal waters is necessary for the understanding and management of the coastal environment. Traditionally, suspended sediment concentration (SSC) has been measured by time-consuming and costly boat surveys which allow the accurate measurement of SSC for single points in space and time. Remote sensing from airborne and spaceborne sensors has proved to be a useful adjunct to such surveys as it provides an instantaneous and synoptic view of sediments that would otherwise be unavailable. The key to the success of remote sensing in such a role is the strong positive relationship that exists between SSC and remotely sensed spectral radiance (L(x)). This review provides an introduction to this SSC/L(x) relationship; exploring its physical basis, its robustness under a range of environmental conditions and its utility as a tool for estimation. It is concluded that future research on this relationship should concentrate upon the suppression of environmental influences and the optimum sampling of SSC.
