| 摘 要： | 本文利用当前国际上比较先进的双向指示一种分析（ＴＷＩＮＳＰＡＮ）和无趋势对应分析（ＤＣＡ）多元等级分划分类和排序方法，运用群落内乔木层树种的重要值，对浙江泰顺乌岩岭常绿阔叶林进行了数量分类和排序，将７个样地划分为三组。其排序图较好反映了群落沿海拔高度和湿度梯度的分布格局。说明ＴＷＩＮＳＰＡＮ和ＤＣＡ对中国亚热带常绿阔叶林的数量分类和排序是有效的。 |

| Abstract: | The quantitative classification and ordination for evergreen broad-leaved rorest on mountain Wuyanling at Taishun county in Zhejiang Province was made by using the programs of TWINSPAN and DCA and importance value of tree layer. The conclusion showed that severn quadrats were divided into three groups. The ordination graph illustrated the distribution of communities with the altitude and moisture gradients. The TWINSPAN and DCA programs are validable to the quantitative classification and ordination of subtropical evergreen broad-leaved forest. |
| Keywords: | Subtropical evergreen broad-leaved forest tree layer importance value TWINSPAN DCA |
