Abstract  

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.

Key wordsSuspended solids      Spectrum      Light attenuation
