| 摘 要： | 在群落样方调查基础上,采用双向指示种分析法(TWINSPAN)和除趋势对应分析(DCA)对莱芜房干村植物群落进行了数量分类和排序。TWINSPAN将20个样方分为7组,根据植被分类的原则划分为7个群落,论述了各群落的群落学特征。20个样方的DCA排序结果反映了植物群落类型与环境梯度之间的关系,表明影响群落分布格局的主要生态因子为海拔高度和坡向。

| Abstract: | According to the data of field plots,the classification and ordination of plant community at Limestone Mountain Area in Fanggan,Shandong Province,were studied using two way indicator species analysis(TWINSPAN) and detruded correspondence analysis(DCA).20 samples were divided into 7 groups by TWINSPAN.Based on the principle of vegetation classification,20 samples were classified into 7 associations and their community characteristics are described.The result of DCA ordination has reflected the relation ship between plant community type and the environment gradient.The results showed that distribution pattern of the associations were mainly affected by the leading ecology factor of elevation and the direction of mountain slope. |
