摘要
依据植物群落的结构,主要层的优势种差异和生境的一致性,对昆明地区常绿栎类萌生灌丛划分群落类型,即滇石栎萌生灌木群落、滇青冈萌生灌木群落、光叶石栎萌生灌木群落、元江栲萌生灌木群落和窄叶青冈萌生灌木群落等五个主要群落类型.分析了群落特征,地上部分生物量与生境条件之间的关系,群落的资源与生态价值等,以提供时常绿栎类萌生灌丛的开发利用,经营保护和植被恢复的科学依据.
In this paper, the evergreen hroad-Ieaved sprouted shrub community is divided on the base of dominant species, characteristic of habitat and community struc ture. There are five community types: Castanopsis orthacantha sprouted shrub communi ty: Lithocarpus dealbatus sprouted shrub community; Cyclobalanopsis glaucoides sprouted shrub community; Cyclobalanopsis augustinii sprouted shrub community; Lithocarpus mairei sprouted shrub community. The characteristics of the sprouted shrub communities are as follow: 1. Their structure and speceis component is simple; 2. Their sprouting potential is very powerful and prosperous, the branch density of dominant spe eies in 7 year sprouted shrub community is about 30, 000 per hactare, the base diameter of branch is 1-3 cm, and the biomass of community is 20- 30 t / hm2
