摘要
在样地调查的基础上,采用双向指示种分析(TWINSPAN)和趋势对应分析(DCA)对福建东山岛海岸沙地风水林进行数量分类和排序研究。结果表明:调查样地共包含101个物种,分属41科82属,禾本科10种、大戟科9种、菊科8种、茜草科7种和芸香科5种所含物种较多。经TWINSPAN分类,36个样地分为13个聚组,根据其指示种确定为13个群丛。样地DCA和物种DCA排序结果反映了植物群丛与指示种之间的一致关系,两排序轴均具有明确的生态学意义,环境因子影响了风水林植被的分布。
Based on the plot investigation,by using TWINSPAN and DCA,the quantitative classification and sequence of the feng-shui forest in coastal zone of Dongshan island in Fujian province were conducted.The results show that there were 101 species which belong to 41 families and 82 genus in the investigated plot,the most abundant families were Gramineae,Euphorbiaceae,Compositae,Rubiaceae and Rutaceae.36 samples were categorized into 13 groups and divided into 13 associations according to the indicator species.The results of plots and species DCA sequence inflected the consistent relationship between the associations and indicator species.The ecological explanation of the two ordination axes illustrated that the environmental factors affected the distribution of Feng-shui forest in this area.
