摘要： 湖泊富营养化的评价,即确定水体的状态属性,实际上是一个将定性问题定量化的多变量的综合决策过程,因此,对湖泊的富营养化程度进行评价应以综合评价为主.在综述国内外若干综合评价方法的基础上,指出营养状态指数(TSI)法应可作为湖泊富营养化评价的主要方法,因其可对湖泊的营养状态进行连续的数值化分级,从而为富营养化机理的定量研究提供坚实基础.采用层次分析(AHP)法确定综合评价指标中的权重分配,构建一综合评价模型:TSI=W(Chla)×TSI(Chla)+W(Sd)×TSI(Sd)+W(TP)×TSI(TP)或TSIM=W(Chla)×TSIM(Chla)+W(Sd)×TSIM(Sd)+W(TP)×TSIM(TP).此外,文中简要讨论了综合评价与其他统计方法如聚类分析的关系.
Abstract: The evaluation of eutrophication or trophic state of a lake is in fact a multivariate comprehensive decision making process quantifying the qualitative problem. Therefore,we should use a comprehensive method to assess lake eutrophication. On the basis of summarizing some comprehensive methods for assessing lake eutrophication reported in China and abroad,it is pointed out that the trophic state index (TSI) should be a major method for evaluating lake eutrophication, since it could provide a continuous numerical class of lake trophic state and a rigorous foundation of quantitative studies of eutrophication mechanism. Using analytic hierarchy process (AHP) to determine the weight attributions in the selected comprehensive indices,the authors,constructed a comprehensive assessment model as: TSI=W(Chla)?TSI(Chla)+W(Sd)?TSI(Sd)+W(TP)?TSI(TP) or TSIM=W(Chla)?TSIM(Chla)+W(Sd)?TSIM(Sd) +W(TP)?TSIM(TP) where W(X) were the weights for the above three parameters with value in percentage as 54.0,29.7 and 16.3,respectively. Additionally,the relations between comprehensive evaluation and other statistical methods such as cluster analysis were briefly discussed.
