浙江楠适生环境研究

Investigation and Analysis on the Habitat of Phoebe chekiangensis

选取2009-2011年浙江省森林生态监测的1 221个样地资料为研究样本,分析天然林中浙江楠的适生环境。结果表明:浙江楠主要分布在浙西、浙南海拔556～925 m的低山和中山,以中下坡为主,分布的土壤主要为红壤和黄壤;浙江楠基本生存于林分的中层,在林分中比较弱势;群落中,浙江楠的生态位宽度值较大,说明浙江楠适合在类似研究样地建立建群优势种群;浙江楠和杉木、木荷的生态重叠值高达0.9以上,说明它们的生物生态特征相似,对生境要求比较相近。

Studies were conducted on data of 1 221 sample plots for Zhejiang forest ecological monitoring during 2009 and 2011. Analysis was made on different habitats of Phoebe chekiangensis at these plots. The results showed that P. chekiangensis mainly distributes in the low and middle mountains with red and yellow soil, at an altitude of 556 - 925 in in the western and southem of Zhejiang. P. chelciangensis grows at the middle layer of forests, relatively weak in the habitat. The niche breadth of P. chelciangensis was high, indicating that it could establish dominant population in the similar habitat. Moreover, the niche overlap among P. cheldangensis, Cunninghamia lanceolata and Schima superba reaches 0.9, showing that they have similar biological properties and need similar habitat
