| 摘 要： | 根据2009年6月巢湖32个样点的实测数据,分析巢湖水体各组分的吸收、后向散射特性以及水体漫衰减系数光谱特征,并通过Lee模型计算各影响因子对漫衰减系数的贡献率,在此基础上,进一步探讨巢湖水体漫衰减系数与各衰减因子浓度的关系.结果表明,非色素颗粒物、有色可溶性有机物(CDOM)吸收均随着波段增加呈现不断衰减趋势,400...

| Abstract: | According to the in situ data of 32 sampling sites which were measured in June 2009,absorption,backscattering properties of different components and the spectral characteristics of diffuse attenuation coefficient(Kd) were analyzed in Chaohu Lake.And then the contribution of each factor's affecting on Kd were calculated by Lee Model.Based on the analysis,the relationship between Kd and the affects were discussed.The result indicate that: the contribution to Kd of nonpigment suspended matter and chromophoric ... |
