不同木荷防火林带建设模式群落学特征比较

Community Characteristics in Different Patterns of Schima superba Biological Fire-Protection Forest Belts

对分布于浙江永康、建德的木荷生物防火林带几种建设模式的群落外貌、群落多样性和群落结构等特征进行初步研究,结果表明:木荷生物防火林带生活型谱和叶的性质与原生木荷常绿阔叶林差异不大,但群落物种多样性指数不高,木荷呈单优势群落;群落垂直结构较差,乔、灌、草分层不明显,不能充分利用空间。

Schima superba is a superior fire protection tree in the south of China. The knowledge of the community characteristics of S. superba biological fire-protection forest belts is crucial to speed up the construction of biological fire-proofing project. This paper presented a preliminary study on phytocoenosis physiognomy, community diversity and community structure of the different patterns of S. superba biological fire-protection forest belts in Yongkang and Jiande in Zhejiang Province. The results indicated that the life type spectrum and the leaf quality had no significant difference between S. superba biological fireprotection forest belts and primary S. superba evergreen broad leaved forest. The S. superba biological fire-protection forest belts had low biodiversity index and it was in monodominant community. The community vertical structure of the belts was quite simple and has only shrub and herb layers, which did not make full use of the space.
