摘要:
2015年 7月,在浙江省凤阳山国家级自然保护区内选择具有代表性,当前潜在干扰小的针阔混交林中建立 50 m×100 m样地。利用空间结构分析软件 Winkelmass和 R软件计算前 10位空间优势树种的空间结构参数,并重点分析主要优势树种黄山松 Pinus taiwanensis和木荷 Schima superba的二元分布特征。结果表明,除木荷属于随机分布外,黄山松等优势树种均属于聚集分布。优势树种多处于中高度混交状态。黄山松和木荷的二元分布特征大致相同,在同一优劣等级或同一混交度等级上的林木多呈随机分布,在低度混交状态,林分中大多数林木大小分化不明显,而在极强度混交状态,林木大小分化十分显著。同一优劣等级上处于强度混交状态的林木较多。林分的空间结构复杂多样,优势树种多呈聚集分布且隔离程度较高,群落结构稳定,演替良好。
Abstract:
A fixed sample plot of 50 m×100 m was established in natural coniferous and broad-leaved mixed forest in Fengyangshan National Nature Reserve, Zhejiang province.Tally was carried out on plants with DBH ≥5 cm and height ≥ 2m in the plot.The result demonstrated that there were 1952 plants, belonging to 63 species of 23 genera and 22 families.Structural parameters of the top 10 dominant tree species were analyzed by Winkelmass, especially on bivariate distribution structural of Pinus taiwanensis and Schima superba in this plot.Results showed that the dominant species were aggregated distribution and had a high mingling degree, except S.superba was random distribution.The bivariate distribution characters of P.taiwanensis and S.superba had a similar frequency, random distribution at the same level of dominance or at the same mingling degree.DBH had not difference in low mingling, but in extremely intensity mixed was significant.It concluded that special structure of the plot was complex and diverse, indicating stable community structure and normal succession.
