| 摘 要：本文研究了鼎湖山以锥栗、荷木、马尾松群落为代表的针阔叶混交林群落的物种组成、水平结构、垂直结构和组织水平结构。在1hm2永久样地内共有95种植物，主要种类为锥栗Castanopsis chinensis、荷木Schima superba、马尾松Pinus massoniana、豺皮樟Litsea rotundifolia var. oblongifolia等。群落乔木层可分为2个亚层，高度分别为4-12m和1-4m， 林下层为灌木层和草本层。 乔木层、灌木层和草本层的平均个体密度分别为0.39、0.68和6.04 N. m-2，多样性指数分别为3.92、4.01、4.21，均匀度分别为0.64、0.76、0.84，生态优势度分别为0.07、0.09、0.10。该群落处于南亚热带地带性植被南亚热带常绿阔叶林顺向演替过程中的以阳性阔叶树种为优势的针阔叶混交林阶段。 |

| 摘 要(英文)：The community structure of the pine and broad-leafed mixed forest were analyzed in Dinghushan，Guangdong，China. The community has 95 species in the permanent plot，with dominant species Castanopsis chinensis，Schima superba，Pinus massoniana，and Litsea rotundifolia var. oblongifolia. The canopy can be divided into two tree layers，one shrub layer and one herb layer. The average individual densities of tree layer、shrub layer and herb layer of the community are 0.39，0.68，and 6.04 N. m-2 respectively. The Shannon-Weiner index of diversity， evenness index，ecological dominance，are 3.92，0.64，0.07 (in the tree layer)，4.01，0.76，0.09 (in the shrub layer ) and 4.21，0.84，0.10 (in the herb layer)，respectively. The pine and broad-leafed mixed forest is developing to climax. |
