摘　　要： 从太阳光在水体中传输的物理机制入手,引入水体光学厚度概念,根据辐射传输理论,推导出悬浮泥沙定量遥感的综合模式,该模式具有明确清晰的物理意义。并且该模式在条件简化下几乎包含了前人所推导的所有半经验模式,包括线性模式、对数模式、Gordon模式、负指数模式、统一模式。将该模式应用于珠江入海口水域的悬浮泥沙调查与监测中,取得了不错的效果。 Based on the physical mechanisms of spectrum transmission in water, an integrated model, which has specific and distinct physical meaning, was presented as a quantitative approach to detect suspended sediment concentration. The water optical thickness was cooperated into this model. Under simplified conditions, the integrated model can almost cover all experiential models and semi_experiential models including the linear model, the logarithm model, the Gordon model, the negative index model and the unified model. This integrated model was applied to detect suspended sediments in the Pearl River estuary, and the results showed that the model can fulfill the quantitative survey of sediments.
