摘要:
2018年7月,在景宁大仰湖湿地群省级自然保护区选择有代表性的针阔叶混交林群落,建立100 m×100 m固定样地,对样地中木本植物群落的物种组成、区系特征、径级结构和空间分布格局4个方面进行调查与分析。结果表明:(1)样地内共记录到植物150种,隶属于53科97属;黄山松Pinus taiwanensis为建群种,其重要值达19.0%;优势种微毛柃Eurya hebeclados的重要值最大,达31.3%;主要伴生种有木荷Schima superba、朝鲜山矾Symplocos coreana、小叶石楠Photinia parvifolia和中华石楠Ph. beauverdiana等。(2)从地理分布类型来看,科的热带分布略高于温带分布;属的温带分布占属总数的57.1%,表现出较为明显的温带区系特征。(3)样地内木本植物群落的径级分布呈现倒“J”形,整体更新良好。仅黄山松的小径级植株数量稀少,导致其自然更新不良。群落垂直结构复杂,分层不明显,几个优势树种分布在不同的乔木亚层。灌木层密度大,物种丰富;草本层较为稀疏。(4)样地乔木层优势种和主要伴生种呈现不同程度的生境偏好性的聚集分布格局。
Abstract:
In July 2018, a typical coniferous and broad-leaved mixed forest community was selected to establish a permanent sample plot with 100 m × 100 m in Jingning Dayanghu Provincial Wetlands Nature Reserve, Zhejiang province. Investigations were completed on species composition, DBH, etc. The results showed that there were 150 plant species belonging to 53 families and 97 genera. Pinus taiwanensis was constructive species with important value of 19%. Eurya hebeclados had the highest important value of 31.3%, and was the dominant species. Main associated species were Schima superba, Symplocos coreana, Photinia parvifolia and Photinia beauverdiana, etc. Family distribution type had tropical properties, but the genus one accounted for 57.1% of the total, showing obvious characteristics of temperate zone. Diameter class distribution of woody plant community showed a typical inverse "J" in the plot with good regeneration. There was few number of small diameter P. taiwanensis, resulting its poor natural regeneration. The vertical structure of the community was complex and the stratification was not obvious. Dominant tree species were distributed in different arbor sublayers. The shrub layer was dense and rich in species. Herb layer was sparse. The dominant species and the main companion species in the arbor layer of the plot had different habitat preference and aggregation distribution.
