摘要
针对湖泊富营养化的综合评价问题,在概述湖泊富营养化评价方法及其应用的基础上,介绍了可拓学评价方法,分析了该法的特点,即具有分辨能力强,不丢失中间信息等优点。将可拓学评价方法用于洪湖的富营养化状态评价,结果表明2005年8月到2006年7月期间洪湖的入湖区、养殖区、开阔区、保护区和全湖的富营养化状态依次为轻富营养、轻富营养、轻富营养、中营养和轻富营养等级。这与模糊数学方法的评价结果一致或接近,说明了可拓学评价方法用于富营养化评价是可行的。
For comprehensive assessment of lake eutrophication problems,in outlining the methods of lake eutrophication assessment,an extension method for evaluation was introduced and its characteristics,the ability to distinguish strong and without loss of information were analyzed.The extension evaluation method has been used to Honghu Lake eutrophication assessment from August 2005 to July 2006.The results show that state of nutrition introduced into lake area,breeding areas,open areas,protected areas and the whole lake are light eutrophic,light eutrophic,light eutrophic,in the eutrophic and light eutrophic in sequence.The evaluation results are consistent with that of fuzzy mathematical method,the method is feasible for eutrophication assessment.
