| 摘 要： | 利用系统聚类分析方法将东阳沟自然保护区森林群落划分为6个群落类型，分别论述了各群落的结构特征．从种群的大小级结构动态和种群的存活曲线方面分析了各优势种群的结构格局．结果，发现华山松群落、云杉群落、毛肋杜鹃群落、杉木群落、楠木和细叶青冈群落为下降种群，而细叶青冈群落为增长种群．由此可见东阳沟自然保护区森林群落多数处于衰退趋势，应加强对这些种群落的保护，以确保群落的稳定性发展． |
| 关 键 词： | 东阳沟自然保护区 群落类型 结构特征 优势种群 |

| Abstract: | The forest communities of the Dongyang Gou Natural Reserve could be divided into 6 types by the method of cluster analysis system and the structural features of each community were introduced.The population structure of each dominant population was analyzed by population structure development and population survival curve.We have found the populations of Pinus armandi,Picea braehytyla,Rhododendron augustinii,Cunninghamia Lanceolata,Phoebe neurantha+ Cyclobalanopsis glauca var.gracilis are declining populati... |
