我国湖泊富营养化防治与控制策略研究进展

随着全球人口的不断增加,工业化、城市化以及农业现代化的快速推进,湖泊富营养化问题已日益成为全球性的水环境污染问题。近年来,我国经济发展提速,资源利用强度加大,导致湖泊氮、磷营养盐严重富集,某些湖泊生态系统结构遭受破坏,功能紊乱,一些区域的湖泊蓝藻水华频繁爆发,湖泊富营养化呈现迅猛发展的趋势,并对区域经济发展与生产、生活用水保障带来挑战。尽管为了防控湖泊富营养化,我国各级政府投入了大量人力与物力,但在一些湖泊富营养化频繁区,一些防治与控制措施还没有收到理想而满意的效果。文章在综述国内外湖泊富营养化防治与控制策略研究的基础上,阐述了我国在富营养化研究方面存在的主要问题,提出了我国湖泊富营养化分区、分类控制的新思路。

Progress on Preventing and Controlling Strategies of Lake Eutrophication in China

Eutrophication of lakes is increasingly becoming one of big concerns for water pollution at a global scale. In recent years,rapid economic development and increase of intensity of resource exploitation result in the enrichment of amounts of nitrogen and phosphorus in lakes,the degradation of lake ecosystem,frequent outbreaks of algae bloom,and more and more severe lake eutrophication,which make regional economic development and productive,domestic water safeguard confront with challenges at regional extent....
