摘要
以浙江天童常绿阔叶林为研究对象,在选取的永久样方中应用每木调查法调查了群落的种类组成,并对群落结构进行了分析。通过收获法直接测定了群落草本层和灌木层的生物量,并采用标准木法间接测定了乔木层生物量,同时分析了该群落及其主要组成树种的生物量特征。结果表明:木荷Schima superba,米槠Castanopsis carlesii为群落优势种,它们与石栎Lithocarpus glaber,栲树Castanopsis fargesii,细叶青冈Cyclobalanopsis myrsinaefolia共同构成了该群落的主要树种。群落生物量主要是由群落内主要组成树种的生物量构成的,主要集中在乔木层,其生物量主要分配在米槠和木荷上,各层生物量绝大多数由主要组成树种的生物量构成,乔木层和灌木层主要树种的生物量器官分配为干>枝>叶。
This study was carried out in the evergreen broad-leaved forest of Tiantong National Forest Park, Zhejiang Province. All the trees in quadrats established in the forest were identified and measured to quantify the community structure of the forest. On this basis, the biomass of the community and its main tree species were measured and analyzed, and the relations between various organ biomass of tree, tree height and diameter at breast were obtained by the method of correlation analysis, the mathematics models for every organ of main species had been established. The results showed that Schima superba and Castanopsis carlesii were the dominant species in the community and constituted the main tree species with Lithocarpus glaber, Castanopsis fargesii and Castanea gracilis. The community biomass was mostly composed of main species biomass in every layer, the biomass of Castanopsis carlesii and Schima superba was respectively dominant in the tree layer which was the main component of the whole biomass. The order of biomass of various organs in the tree and shrub layer was trunk 〉 branch 〉 leaf. [ Ch, 2 fig. 3tab. 17 ref. ]
