城市景观水体富营养化现状及成因

Discussion on Present Situation and Formation of Eutrophication in Urban Landscape Water

综述了全国各地城市景观水体富营养化现状,分别从水动力条件、水体更新周期、生物多样性、底泥释放等内因,补水水源、水体负荷和人为污染等外因分析了城市景观水体富营养化成因。以期为城市景观水体富营养化的治理提供切实可行的理论依据。

This article summarized the present situation of eutrophication in urban landscape water, it also analyzed the cause of eutrophication from the aspects of the internal and external causes respectively. The internal causes include hydrodynamic conditions, renewal period of water body, biodiversity and pollutants released from sediments. The external causes are water source for supplement, pollution load of water and human contamination. This article hopes to provide a feasible and practical theoretical basis for the management of the eutrophication n urban landscape water.
