| 摘 要： | 根据野外调查的样地资料,分析了分布于青海大通东峡林区金露梅灌丛群落的种类组成、垂直结构等基本群落特征,并将金露梅样方以及上层无乔木覆盖灌木为建群层的金露梅样方归为7个群系。结果表明:该群落种类组成丰富;区系成分以北温带分布为主;生活型以地面芽占优;垂直分化明显;7个群系地理位置不同,生态环境特点各异、种类组成不一,因而各个群系中主要灌木种群的分布格局也有特点,不很一致;各群系中主要灌木种群的分布格局一般为集群型,少数随机型。 |

| Abstract: | According to the data from field plots, the preliminary characteristics such as floristic composition, vertical structure of Potentilla fruticosa shrub community were studied in Dongxia forest area of Qinghai province. The samples, which have no tree stratum above them, were divided into 7 formations. The results shows that the floristie composition of the community is plentiful, the temperate floristic elements occupy a dominant position, hemicryptophytes is dominant, the vertical structure is obvious, because the geographical position and the living environment are different in the 7 formations, the floristic composition are different, distribution of the main shrub population in different formation was different. Most of the main populations in 7 formations tend to contagious distribution, only a few distribute randomly. |
| Keywords: | Potentilla fruticosa community floristic composition community physiognomy vertical structure formation distribution pattern |
