吕泗渔场水环境质量现状

Situation of environmental quality in Lvsi fishing ground

采用多种方法定量评价了吕泗渔场水体的环境质量,并分析了其影响因素。研究结果表明:吕泗渔场水体主要受到沿岸陆源污染和海上交通污染的影响,主要超标物为无机氮(D IN)和活性磷酸盐(PO4-P)。吕泗渔场大部分水体富营养化严重,环境质量日趋恶化。应根据水域纳污能力,实施陆源污染物总量控制。

The assessment on quality and influence factors of water column were done in the coast of the Lvsi fishing grounds by several methods. The results showed that： the major pollution resources were from the land and water-borne transportation pollution, and the major pollution factors were TIN and PO4-P. Because of serious eutrophication, the water quality of Lvsi fishing ground was worse. Total mass control of the pollutant discharge should be carried out according to the sea water itself purified ability for the pollutants.
