摘　　要：根据浙江省江山市80个公益林固定小班的监测数据,在对不同群落类型(松林、杉木林、阔叶林、针阔混交林、毛竹林和灌木林)的生物量计算和群落结构分析的基础上,运用物种丰富度(S)、Simpson指数(D)、Shannon-Wiener指数(H')和Pielou指数(J)估评群落生物多样性特性。利用改进的Godron M稳定性测定方法对江山市公益林群落稳定性进行评估,并通过主成分分析法对6种群落的相对稳定度进行进一步分析评价。结果表明:江山市公益林群落总体多样性可观,生物多样性排序为常绿阔叶林>针阔混交林>松林>杉木林>毛竹林>灌木林;江山市公益林群落处于稳定状态,且群落稳定性与生物多样性呈正相关关系。With 80 permanent sample plots of ecological service forest （ESF） of Jiangshan city in Zhejiang province, an investi- gation was conducted to study the biomass and community composition of main forest types of ESF： Pine （Pinus massoni- aria） forest, China fir （ Cunninghamia lanceolata） forest, evergreen broadleaved forest, coniferous and broadleaved mixed forest, phyllostachys heterocycla forest and Shrub forests by four diversity indexes： the species richness （S）, the Simpson index （D）, the Shannon-Wiener index （H＇） and the Pielou index （J）. The stability of ESF and each community in Jian- gshan were evaluated by the improved M-Godron method and principal component analysis. The community biodiversity was evergreen broadleaved forest〉coniferous and broadleaved mixed forest〉pine forest〉China fir forest〉PhyUostachys het- erocycla forest〉Shrub forests. The ESF of Jiangshan is in a stable state, and the community stability is evergreen broad- leaved forest〉coniferous and broadleaved mixed forest〉pine forest〉China fir forest〉Phyllostachys heterocycla forest〉Shrub forests. There is a positive correlation between the community stability and biological diversity. It also plays a positive role in construction and management of ESF, and provides gist for construction and management of ESF in Zhejiang Province.
