呼伦湖、太湖和滇池总磷基准与控制标准制定探讨

目的]制定湖泊总磷基准与控制标准。方法]采用概率统计与Carlson模型分析相结合的方法,并以呼伦湖、太湖、滇池为例,制定湖泊营养物总磷(TP)基准与控制标准的参考值。结果]呼伦湖、太湖和滇池水体中营养盐的含量一直处于富营养化状态,呼伦湖属于自然主导型富营养化湖泊,其他2个湖泊属于人为主导型富营养化湖泊。对于3个湖泊水体中TP基准与控制标准的参考值,呼伦湖分别为0.08和0.20 mg/L,太湖分别为0.03和0.06 mg/L,滇池分别为0.06和0.15 mg/L。结论]制定的3个湖泊营养物总磷的基准和控制标准值为湖泊富营养化控制提供了重要依据。

Formulation of The Criteria and Control Standard of Total phosphorus in Hulun, Taihu and Dianchi Lakes

Objective] The study aimed to formulate the criteria and corresponding control standard of total phosphorus(TP) in lakes.Method] The reference values of criteria and control standard for total phosphorus in Hulun,Taihu and Dianchi lakes were formulated using probability statistics and model analysis.Result] The content of nutrients in Hulun,Taihu and Dianchi lakes were always in an eutrophication state,and Hulun Lake was a naturally dominated eutrophic lake,while Taihu and Dianchi lakes were anthropogenically dominated eutrophic lake.In addition,the reference values of TP criteria and control standard were 0.08 and 0.20 mg/L respectively in Hulun Lake,0.03 and 0.06 mg/L respectively in Taihu Lake,and 0.06 and 0.15 mg/L respectively in Dianch Lake.These phosphorus criteria and control standards in three lake are very useful for lake eutriphication control.Conclusions] These criteria and control standards of total phosphorus in the three lakes are very useful for lake eutrophication control.
