| 摘 要： | 以英国威尔士北部Ｓｎｏｗｄｏｎｉａ山地Ａｂｅｒ山谷植被为例，对模糊ｃ－均值聚类和ＴＷＩＮＳＰＡＮ分类进行了应用和比较研究。两种方法的结果一致。模糊ｃ－均值聚类结果给出样地和植被类型间的隶属程度，在一定程度上优于ＴＷＩＮＳＰＡＮ。

| Abstract: | Fuzzy c-means algorithm clustering and TWINSPAN (Two-way indicator species analysis) were applied to the classification of woodland and moorland grasslands in Aber Valley in Nortbern Snowdonia,Wales and their results were compared with each other. These two methodologies provided identical results.However, fuzzy c-means clustering is,to some degree,superior to TWINSPAN because its results were shown by memberships. |
