摘要
通过对研究地区的路线调查和样地调查、Cluster Analysis聚类、NMDS排序,分析海南岛清澜港潮间带植被类型及群落的空间分布,研究潮间带植被群落在空间上的分布规律。结果表明:①Cluster Analysis聚类、NMDS排序的结果显示,可将清澜港地区51个样地划分为1个植被类型组、1个植被类型、2个群系组和7个群系,不同群系在物种组成和立地条件上均有差异;②从排序的结果可以看出群落和环境的关系,NMDS排序轴的第一轴上呈现清澜港植被群落在潮间带上的水平带状分布特征,在排序轴的第二轴上呈现植被群落受潮位控制,在空间上成规律的梯度分布状态。
The spatial distribution, distribution patterns and spatial succession laws of intertidal zone vegetation in Qin-lan harbor areas in Hainan were studied by using quadrat method, cluster analysis, NMDS ordination analysis. The results showed that： （1）51 plots could be clas- sified into 1 Veg. Tape group, 1 Veg. Tye, 2 Form. group and 7 Form by using cluster analysis and NMDS. The species composition and site conditions have differences in different form. （3） The relation between community and environment could be shown by NMDS： The first axis of NMDS ordination expresses the vegetational communities distribution characteristics that is horizontal bands distributions. The two axis of NMDS ordination showed that the distribution of vegetations controled by tide level. （3） In the course of interaction between vegetation commu- nities in intertidal zone and the environment formed a very distinctive successional series. There didn＇ t appear the top stage of community suc- cession and climax community.
