摘要: 对在梅子垭及其毗邻地区若干重要水体所取的10个水样及其pH值、总氮、总磷、PO43-态磷和P2O5态磷进行了聚类和主成分分析。聚类分析表明10个水样可分为两大类,其中一类又明显分为两类。主成分分析表明磷对第一主成分的贡献最大;氮对第二主成分的贡献最大,其值为负表示存在负相关,排序时将会影响水样在第二主成分上的排列方向。

Abstract: In this research, taking the factors as pH value, total nitrogen(N), total phosphor(P), PO33--P and P2O5-P, cluster analysi s(CA) and principal component analysis(PCA) of 10 important waters in Meiziya Vi llage and its contiguous regions were carriedon CA showed that the ten waters co uld be classified into two categories, and one of which could be classified into two categories, too. PCA showed that P contributed to the first principal compo nent most and N contributed the second principal component largely The factor sc ore coefficient of N being negative meant there existed negative relationship, a nd it could affect the arrange direction of water samplings in the second princi pal component.
