水体富营养化与水体沉积物释放营养盐

Eutrophication of the water body and release of nutrient salts from sediments

水体富营养化已经成为世界水环境面临的最为重要的问题。简要介绍了中国水体富营养化的现状和水体富营养化的成因。着重阐述了在截断外源污染后,水体沉积物对营养盐的释放及其主要影响因素,并提出了目前存在的问题和未来的发展方向,为水体富营养化的研究、预防和治理工作提供了系统、科学的理论依据。

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.
