| 摘要: |
| 以聚类中正相(Q)分析方法对19座水库进行了营养类型的分类,并与模糊聚类分析进行了比较。同时,建立了水库营养类型0—1高指标的判别方法。最后,设计了通用的分析和计算程序,并指出水库营养类型分类中还需进—步解决的问题。 |

| Abstract: |
| The trophic levels of 19 reservoirs have been classified by using Q-matrix in cluster analysis and its comparison with fuzzy cluster analysis has also been made, and a new 0-1 higher index discrimination for the trophic level classification of one reservoir has been established. All methods are transferred into computer programmes and the impending problems of the trophic level classification are put forward. |
| Key words: Cluster analysis 0—1 higher index discrimination |
