摘　　要：为了解赤皮青冈的群落结构,预测其群落动态变化,对福建建瓯上元村赤皮青冈人工混交林进行植被调查,以物种丰富度、多样性指数、优势度指数和均匀度指数作为多样性测度指标对样地进行统计分析,采用Levins测度式和Lotka-Volterra竞争模型研究群落中优势树种的竞争关系。结果表明:样地内共有乔木20种,612株;灌木35种,249株;草本33种,1 364株;群落中灌木层物种丰富度最高,多样性指数、优势度指数和均匀度指数均为草本层>灌木层>乔木层;赤皮青冈在与杉木、栲树、木荷间的竞争均处于劣势地位,与钩栲、白花泡桐、青冈、木油桐间的竞争占优势。In order to understand the community structure and predict the development of the community, investigation of vegetation in the plantation of Cyclobalanopsis gilva in Jian＇ou City, Fujian Province. Using four indexs （ species richness index, Shannon-Wienner index, dominance index, and evenness index ） , and Levins-type measurement and Lotka- Voherra competition model, the plant species diversity were analyzed, and the competitive relationship between the dominant species in the community were researched. The results showed that： There are 20 arbor species with 612 trees, 35 shrub species with 249 plants, 33 herb species with 1364 plants; Species richness index value of shrub layer is the highest, Shannon-Wienner index, dominance index, and evenness index at the different layer in order is herb 〉 shrub 〉 arbor; Cyclobalanopsis gilva has disadvantages in competition for space and resources with Cunninghamia lanceolata, Castanopsis fargesii and Schima superba, and has advantages in competition with Castanopsis tibetana, Paulownia fortunei, Cyclobalanopsis glauca and Vernicia montana.
