This paper deals with studies on the similarity of the athropod communities in paddy fields located in different habitats and their cluster analysis by using the data obtained from both Yangjing County, Guangdong Province and the suburban districts of Fuzhou, Fujian Province. The formula of Eculidean distance was used to measure the similarity index between the different communities. The results showed that the structure of the communities in the different habitats of the same district were basically similar. It could be shown that there were some differences in the commmunities betweeen Yangjiang and Fuzhou by comparing the similarity indices. The cluster analysis indicated that the communities in different habitats could be clustered at larger values of the similarity index and could provide farmers with references for 1PM.

本文利用在广东省阳江市、福建省福州市效区两地的田间调查资料,研究不同生境区稻田节肢动物群落的相似性并进行聚类分析。经用欧氏距离的公式测定不同群落实体之间的相似性指数,表明在同一个地区的不同稻田,节肢动物群落的结构是基本相似的;通过比较福州与阳江的材料及相似指标,可以看出这两个地方的群落是有差异的。聚类结果反映了不同生境区的景观及生态异同性。

This paper deals with the distribution characteristics of shrub communtity from the southern part,middle part and northeast part in Haitan island.According to the agglomerative analysis between the similarity indexes of shrub species in 6 surveyed areas consisting of 24 plots,384 m 2 in Haitan island.These shrub communities may be divided into two distribution groups,i.e,northeast Haitan island group and southwest Haitan island group.And they are made a regular distribution rely on elevation and precipitation.In addition,these dividing results are similar to the division of floristis geographical elements of the shrub communities.The result indications that no matter from horizontal distribution or vertical distribution the geographical distribution of shrub community in Haitan island exists a little difference variability.It is same as the local reconnaissancing result.

据对海坛岛南部、中部和东北部选取的6个地区24处样地,384m2灌丛群落的调查,以地区间灌木种多频度相似性指数作地区聚类和排序分析,得出海坛岛东北部和西南部两个地区组合,它们依海拔和降水量作略有规律的分布.另据以上地区灌丛群落的灌木地理成分及其种优势度分析,也都取得和地区聚类、排序相对应的结果.海坛岛的灌丛群落地理分布无论是水平分布还是垂直分布都存在着略有差异的变化特点,这与当地勘察结果一致.
