| 摘 要： | 利用Wetlabs公司研制的AC-S和BB9于2006年10月24目至11月2目对太湖水体的散射系数和后向散射系数进行了测量，在此基础上建立了太湖水体散射系数与后向散射系数之间的关系模型。用2种曲线函数模拟，即在蓝光波段使用S形曲线模型，在绿光和红光波段使用逆函数模型，各模型的MAPE和RMSE变化范围分别为0.027-0.156m^-1、0.005-0.050m^-1，模型整体预测精度都较高。研究发现后向散射系数与散射系数的空间分异现象明显，北部梅梁湾、湖心区、西部及西南部水域散射较强，而东太湖、胥口湾等东部水域的散射相对较弱。

| Abstract: | Based on water inherent optical properties using AC-S and BB9, which were developed by WETlabs Inc, the backscattering and scattering coefficients of Lake Taihu waters had been obtained from Oct. 24th to Nov. 2rd, 2006. Based on data analysis, the models between backscattering coefficients and scattering coefficients had been established. Two kinds of curve functions had been used to simulate, i.e. S curve at blue waveband and inverse function at green and red wavebands. And the change ranges of MAPE and RM... |
