太湖梅梁湾水体中悬浮质及光谱的分布特征

在研究太湖梅梁湾水体中的悬浮质及水体中光谱分布时发现:总悬浮质中无机悬浮质含量与总悬浮质之间呈现明显的正比线形关系(R²=0.9724),而有机悬浮质与总悬浮质之间的正比线形关系较弱(R²=0.2921);在20cm处以下,总悬浮质中的藻类含量随着水深度的增加呈现下降的趋势,表面略低;有机悬浮质与叶绿素a的含量之间的线形关系较弱(R²=0.1344);光谱的分布特征是:在水体的表面,绿光最强,蓝光较强,而红光最弱;在150cm以下,红光最强,绿光较强,蓝光最弱。

Suspended solids and its optical characteristics in Meiliang Bay, Taihu

Suspended solids and its effects on the underwater light in Meiliang Bay, Taihu was studied and found: Inorganic suspended solids in the total suspended solids had the apparent positive linear relationship with the total suspended solids ( R2= 0.972 4), but the organic suspended solids is slightly relationship with total suspended solids(R2= 0.292 1); The algal content in the total suspended solids decreased with the increasing water depth and at the depth of 20 cm the algal content was the highest, in the surface water the content was lower than that at the depth of 20 cm. The relationship between organic suspended solids and chlorophyll a was less significant(R2= 0.134 4). The distribution of spectrum was that the intensity of green light was the greatest, blue light greater, red light the weakest in the surface water, the intensity of red light was the greatest, green light greater, blue light the weakest.
