Factors and processes such as intense human activities and rapid eutrophication. controlling the concentrations of organic substances, nutrients and organic pigments in sediments were analyzed before and after fish culturing in four fishponds. Results show that rapid sedimentation rate is more favorable for reservation of pigments that can be a significant indicator for trophic state of water bodies. In the meantime, there are close relations among organic substances, nutrients and organic pigments in sediments. These can be useful in sedimentary environmental explanatioa by way of organic pigments index.
