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.
