摘要
通过对昆明地区滇青冈萌生灌木群落优势种滇青冈萌枝的高生长、基径生长、生物量和生长量的研究,特别是滇青冈每个根桩上的萌枝数和萌枝群体生物量之间关系的研究,建立了高生产力优化群落结构.研究结果表明,优化的群落结构每个根桩上保留5个萌枝,每平方米保留2.2个萌枝,可使萌枝群体的生物量最大.建立优化的群落结构还要采取相应的措施,如去密留疏、去小留大、去弱留强等,这样才能充分发挥萌生灌木群落的优势。
In this paper, writer tried firstly to set up the optimal community structure with the biomass of community. By studying the condition of Cyclobalanopsis glaucoides sprouted shrub community structure, the height growth, the base diameter growth, biomass and the gross average growth rate of Cyclobalanopsis glaucoides, especially the relationship between the amount of sprouted branches per root piling and the biomass of sprouted branches colony, it can be seen:if 5 branches were reserved per root piling and branches per metares square the biomass of sprouted branches colony can reach the maxmium. This is the optimal community structure. Setting up the optimal community structure needs to adopt corresponding measures, for example, reserving sparse branches instead of dense, reserving bigger instead of smaller, and reserving strongger instead of weaker, thus the superiority of sprouted shrub community can be completely given play to and the amount of forest resources per area can be improved greatly.
