摘　　要：我国黄东海水体散射特性非常复杂,这是造成该海域水色区划特点显著的原因之一。文中利用2003年4月黄东海试验数据（HD200304）对总悬浮物（TSM,Total Suspended Matter）的后向散射概率bbs和单位散射系数bs^＊进行研究。基于对现场数据的统计分析,我们开发了总悬浮物后向散射概率模型,通过相对偏差分析表明,有近90%的样品反演相对偏差控制在±30%之内。对总悬浮物单位散射系数研究时,选择555 nm为参考波段,开发了不同波段间总悬浮物单位散射系数关系模型,通过相对偏差分析表明,有近94%的样品反演相对偏差在±10%之内,反演效果非常好。The scattering properties of ocean sea water is very complex in the Yellow Sea and East China Sea, it is one of the reason for difficult partitioning. In this paper, the authors use the HD200304 data to study the specific scattering coefficients and backscattering probability of total suspended matter. The authors developed a model about the backscattering probability of total suspended matter based on situ data. The inversed value matched the measured value very well, in 90% of the samples the relative error is controlled in 30%. Then they developed a model about the specific scattering coefficients of total suspended matter by choosing 555nm as a reference wave band. The inversed value matched the measured value better more than above, the relatively error is controlled in ±10% for 94% of the samples.
