Reservoirs in southeast China are important water resources for economic and social sustainable development, although few have been studied previously. During the past decade, growing population and increasing demands for water shifted the focus of many reservoirs from flood control and irrigation water to drinking water. However, eutrophication has become the most prominent and serious pollution problem for drinking water sources in China. Many studies have been made on eutrophication in large shallow lakes, but little is known about deep reservoirs in Fujian province, subtropical China. This project will investigate the tempo-spatial characteristics and microbial mechanisms of trophic state variation in the stratified reservoirs based on multi-parameters (nitrogen, phosphorus, chlorophyll a, Secchi disk transparency and microbial community) with emphasis on both structure and function of microorganisms (algae, bacteria and protozoa) in the subtropical Fujian province. This study will fill a major gap in the knowledge of the trophic state variation of Fujian stratified reservoirs while also contributing to research on microbial ecology and diversity during eutrophication process. This study will have direct theoretical implication for the eutrophication management and algal bloom control and practical implication for sustainable reservoir management and protection, water quality biomonitoring and early warning.
