| 摘 要： | 用因子分析法和相关的统计方法研究了山丹湖的富营养化特征．从原始数据的相关矩阵出发，提取了占总方差８２％的两个主因子，并对主因子作出了合理的解释．主因子分析的结果表明，由氮营养化引起的污染是控制山丹湖富营养化水化学特征的主要因子．

| Abstract: | Factor analysis was used to study eutrophication in Sandan Lake. Twelve samples were collected monthly to determine NH - 3,NO - 3,NO - 2,PO 3- 4, DO, hardness, pH, temperature, transparency and biomass. Based on the correlation matrix of the data sets, a two factor model was extracted to interpret the aquatic chemical characteristics of the lake. The result of the factor analysis showed that the eutrophication caused by nitrate is the most important factor determining the aquatic chemical characteristics in Sandan Lake. |
