Summing up the research on eutrophication mechanisms of lakes and reservoirs

This article summarizes the current status of research on eutrophication mechanisms of lakes and reservoirs,including the relations between each primary factor and its performance during the water eutrophication process. It examines the factors limiting algae growth; the relations between chlorophyll a, total nitrogen and total phosphorus concentration; and hydrometeorology conditions that exist while the water bloom is eurring. Algae characteristics during the water eutrophication process, such as the typical pollution specie indicators, the community diversity and the algae growth potential, are described briefly. The concept of lake ecosystem health and the theory of material circulation of the lake ecosystem are introduced. It is indicated that eutrophication is in essence an ecological imbalance.
