群落类型

崇明岛群落类型比上海地区自然分布的群落类型丰富，（5）本文运用层次分析法和Delphi专家调查法，建立生态和景观相协调的群落评价指标体系。

Chongming Island community type than the Shanghai area rich natural distribution of community types ,( 5 ) In this paper , AHP and Delphi expert survey , the establishment of ecological and landscape in harmony community evaluation index system .

TWINSPAN将115个样方分为11个群落类型。

11 community types were classified y TWINSPAN .

相似性系数Sorenson指数（Cs）的测度表明，每一群落类型总是与退耕年限最邻近的群落具有最高的相似度。

Sorenson 's similarity index ( Cs ) indicated that the similarity between every community and its nearest abandoned time was the highest .

不同季节各群落类型土壤硝态氮含量垂直规律不明显，仅5月0～10cm层的含量明显大于其它层次；不同季节各群落土壤的铵态氮没有垂直分布规律。

However , there were no vertical distribution trends of the nitrate and ammonium nitrogen contents in all four community soils in different seasons , only the nitrate nitrogen content in 0 ~ 10 ?

结果如下：用TWINSPAN进行的数量分类，共划分出12个群落类型，分类矩阵图明显反映出演替时间与土壤含水量两个环境梯度。

CCA , DCCA . The results are as following : plant communities are classified into 12 types by TWINSPAN , and they reflect changes of two environmental gradients , time of succession and water conditions of soil .

运用TWINSPAN把样方分为8个群落类型，用Levins、Shannon-wiener生态位宽度公式和Petraitis生态位特定重叠指数公式测定群落中主要种群生态位宽度和生态位重叠，并分析各种群生态位的生态学意义。

68 quadrats were divided into eight types of communities by TWINSPAN , which can be treated as one-dimension resource states . The niche breadths and overlaps of main dominant species were measured using a series of indices proposed by Levins , Shannon-wiener and Petraitis .
