      Abstract: Eutrophication of the water body has been the most important environmental problem in the global water environment. The paper introduces the concept, present situation and cause of water body eutrophication in China. The focus is on the influence of nutrient salts released from sediments on water quality after cutting external nutrient sources of eutrophic water bodies. Furthermore, the existing problems and future direction are presented. Those offer the systemic and scientific theoretical basis to the study of eutrophication and its prevention and control.
