Effect of Sediment Treatment as Environment Factor on Ecosystem Community Structure

Abstract

This study was conducted to investigate the effect of sediment treatment as environmental factor on ecosystem community structure using experimental microcosm. As results, sediment treatment was made clear to influence to bio-community structure, for both sulfur in sediment and phytoplankton in water are able to be removed simultaneously, T-N/T-P mass ratio was set to around 10, and, the eutrophicated water condition as water-bloom dominated was improved as oligotrophic water condition. Furthermore, the necessity of consideration for bio-diversity level was pointed out because of sediment treatment’s environmental factor effect.
