摘 要:根据浙江省缙云县150个公益林固定监测小班2013年到2015年连续3年的监测数据,在对主要群落类型,即松林、杉木林、阔叶林、针阔混交林、毛竹林和灌木林的优势种确定的基础上,运用Simpson指数(D)、Shannon-Wiener指数(H’)和Pielou指数(J)评估群落生物多样性并推算了群落生物量。根据连续监测结果表明:缙云县公益林优势种稳定,主要为马尾松(Pinus massoniana)、杉木(Cunninghamia lanceolata)、毛竹(phyllostachus heterocycla)、木荷(Schima superba)、茶(Camellia sinensis)等;植物多样性在不同层次中表现为灌木层>草本层>乔木层;松林的总生物量最高,灌木林最低。基于此,可以表明缙云县公益林生长状况良好,同时也对今后的公益林建设提出了一些意见和建议:(1)加大对林分的改造,在持续发挥林分经济效益的前提下,通过人工措施对林分进行高度集约的改造经营,在加快针叶林的阔叶化改造的同时,加大对灌木层和草本层的经营;(2)在今后的经营中应该注重对优势种群的抚育,改造和提升阔叶林及其他林种的质量,加速群落的正向演替;(3)加大对毛竹林的抚育、改造,不断改善提升毛竹林质量,从而提升生物量和生物多样性。Based on three period field survey data of public-welfare forests, the pine forest, cunninghamia lanceolate forest, broad-leaved forest, coniferous, broad-leaved mixed forest, bamboo forest and shrubbery were identified as the dominant community types in Jinyun County, Zhejiang province. Community biodiversity and biomass are also calculated using Simpson index(D), Shannon Wiener index(H') and Pielou evenness index(J). The results showed that the dominant species of the public-benefit forest in Jinyun County were stable, which included Pinus massoniana, Cunninghamia lanceolata, Phyllanthus heterocycla, Schima superba, and Camellia sinensis. The diversity showed shrub layer herb layer arbor layer at different levels; the pine forest had the highest total biomass, and the shrubs had the lowest value. It indicates that the growth of public welfare forests in Jinyun County is in good condition. Some opinions and suggestions are put forward for the future development of public welfare forests. Firstly, the transformation of forest stands should be increased; we should also accelerate the broad-leaf reconstruction of coniferous forests and increase the cultivation of shrub layer and herbaceous layer, to improve the economic benefits of forest. Secondly, in the future operations, attention should be paid to the tending of dominant populations. We should renovate and upgrade the quality of broad-leaved forests and other forest species to accelerate the positive succession of communities; Finally, we should increase the tending and transformation of bamboo forests, and constantly improve the quality of bamboo forests, so as to increase biomass and biodiversity.
