摘要
基于主成分分析理论和SPSS统计软件,建立湖泊富营养综合评价模型,以云南省九大高原湖泊为例,对滇池等九大高原湖泊营养状态进行综合评价,并与指数评价法评价结果作对比分析。结果表明:基于主成分分析法的湖库营养状态综合评价能较好地反映云南省九大高原湖泊营养状态,综合评价结果优于指数法。
A model has been established to evaluate the eutrophication of the nine plateau lakes in Yunnan based on the principal component analysis theory and SPSS statistical software.This evaluation result has been compared with that of the index evaluation method.It shows that the former evaluation method is better than the latter in presenting the nutrition status of the lakes.
