本文详细分析了海水信道的光学特性，梳理了光在海水中衰减的主要影响因素，建立了以叶绿素浓度为衡量指标的生物光学模型；并通过研究高斯光源分布函数、媒介光传输函数，建立了高斯光源的光束传播函数模型；以此为基础，开展了多种水质情况下的仿真实验，为水下可见光通信的信道空间特性研究提供了完整可行的方法参考。
To understand the spatial characters of underwater visible light channel, this paper analyzed the optical characters of underwater channel. The main factors which influence light attenuation in water were described. And a biological optical model with chlorophyll concentration was established. Through the study of gaussian distribution function and medium optical transmission function, a beam transmission function model using gaussian was built. The simulation experiments were carried out under different type of water conditions. This paper provides a complete and feasible reference for the study of the spatial characters of underwater visible light communication channel.
