摘　　要：[目的] 探索森林恢复方式,改善杉木Cunninghamia lanceolata林林分结构及维护生物多样性,对杉木人工林可持续经营和森林恢复活动具有理论和实践价值。[方法] 2017年10月选择浙江省杭州市临安区昔口村二代萌芽杉木幼龄林为研究对象,对其植物群落特征进行实地调查。[结果] 昔口村杉木萌芽幼龄林植物种类共104种,其中乔木层植物14种,灌木层植物58种,草本层植物41种,优势植被构成杉木-蓬蘽Rubus hirsutus-蕨Pteridium aquilinum群落;物种丰富度指数、Simpson指数、Shannon-Wiener指数、Pielou指数均为灌木层>草本层>乔木层;林下植被除部分优势种长势较好,多数植物种类数量较少且分布较稀疏。[结论] 在改善森林生态系统物种、结构、资源利用方面的异质性时,要考虑当地农户和社区的需求,选择当地乡土阔叶树种、适生阔叶树种进行补植,形成混交林,并辅以科学的抚育措施。Objective This study aims to explore the way of forest rehabilitation, improve the forest structure, maintain biodiversity and provide a reference for further research on plant community characteristics of Cunninghamia lanceolata forests. Method A field investigation was conducted on the plant community characteristics of the second generation young C. lanceolata sprout forest in Xikou Village, Lin'an, Zhejiang Province in October 2017. Result The data analysis showed that there were 104 species of plants in the young C. lanceolata sprout forest in Xikou Village, including 14 species of arbor layer plants, 58 species of shrub layer plants, and 41 species of herbaceous layer plants. The dominant vegetation constituted the C. lanceolata-Rubus hirsutus-Pteridium aquilinum community. The species richness index, the Simpson index, the Shannon-Wiener index, and the Pielou index were all shrub layer > herbal layer > tree layer. Except for some dominant species, most plant species of understory vegetation were small in number and sparsely distributed. Conclusion It is recommended that needs of local farmers and communities should be taken into consideration to improve the heterogeneity of forest ecosystem species, structure and resource use, and local native broad-leaved tree species and suitable broad-leaved tree species should be selected for replanting to form mixed forests, supplemented by scientific cultivation measures.
