中国富营养化湖泊的生物修复

中国富营养化湖泊的生物修复顾宗濂�(中国科学院南京土壤研究所,江苏南京�210008)摘要:描述了中国湖泊富营养化污染现状,论述了湖泊富营养化形成的机理、生物修复富营养化湖泊(尤其是去除水体和底泥碳、氮、磷)的理论依据;提出了修复湖泊富营养化的技术途径,阐明了笔者对机械清淤和生物修复各自具有的优势和缺陷的看法。关键词:湖泊;富营养化;机理;生物修复;理论;案例中图分类号:X524;X172��文献标识码:A��文章编号:1001-5906(2002)01-0042-04BioremediationofEutrophiedLakesinChina.GuZonglian(InstituteofSoilScience,ChineseAcademyofSciences,NANJING210008):RuralEco�Environment,2002,18(1):42-45Abstracts:BasedonthecurrentsituationoflakeeutrophicationinChina,primaryindexesforeutrophicationofthelakeswereenumer�ated.Mechanismforlakeeutrophicationandtheoreticalbasisforbioremediationofeutrophiedlakes(especiallyremovingcarbon,nitro�genandphosphorousfromthewaterbodyanddepositoflakes)werediscussed.Onsuchabasis,technicalapproachestobioremediationoflakeeutrophicationwereproposed.Besides,advantagesanddisadvantagesofmechanicaldredgingandbioremediationwereanalyzed.Keywords:lake;eutrophication;mechanism;bioremediation;technicalapproach;case��目前,中国湖泊污染情况严重,80%以上的湖泊受到污染,许多湖泊已达不到�类水水质标准,鱼虾基本绝迹,而代之以适应污染的各类底栖微小生物类
