摘要:  为了解浙江省磐安县高姥山和大盘山国家级自然保护区内金缕梅(Hamamelis mollis)种群的发展动态,应用生态位宽度、生态位重叠模型和单木竞争模型对金缕梅种内及其与常见伴生种间的竞争关系进行了研究。结果表明,群落中金缕梅的生态位宽度最大,其次为四照花(Cornus kousa sp. chinensis)。金缕梅与其伴生种生态位的重叠值为:四照花 > 尖萼紫茎(Stewartia sinensis var. acutisepala) > 云锦杜鹃(Rhododendron fortunei) > 小叶白辛树(Pterostyrax corymbosus) > 郁香野茉莉(Styrax odoratissimus) > 天台鹅耳枥(Carpinus tientaiensis) > 红枝柴(Meliosma oldhamii) > 尖连蕊茶(Camellia cuspidata) > 南方千金榆(Carpinus cordata var. chinensis) > 红果钓樟(Lindera erythrocarpa) > 化香(Platycarya strobilacea)。根据Hegyi单木竞争模型,金缕梅的种内竞争强度大于种间竞争,且以胸径为15~20 cm时达到最大。采用幂函数模型模拟和预测,当金缕梅胸径大于22.5 cm后,其种内和种间的竞争强度趋于稳定。因此,在经营金缕梅人工林时,建议选择灌木树种作为其主要伴生种,可兼植少量高大乔木,但应避免选择萌枝能力较强的小乔木。

Abstract:  In order to reveal the development dynamics of Hamamelis mollis population in Gaomushan and Dapanshan Nature Reserves, Pan'an County, Zhejiang, the intra-specific and inter-specific competitions of H. mollis were studied by using the methods of niche and Hegyi's competition model for individual tree. The results showed that the niche breadth of H. mollis was the greatest in the community, and Cornus kousa sp. chinensis was followed. The niche overlaps between H. mollis and accompanying species were in the order of Cornus kousa sp. chinensis > Stewartia sinensis var. acutisepala > Rhododendron fortunei > Pterostyrax corymbosus > Styrax odora- tissimus > Carpinus tientaiensis > Meliosma oldhamii > Camellia cuspidata > Carpinus cordata var. chinensis > Lindera erythrocarpa > Platycarya strobilacea. Acoording to Hegyi's competition index model for individual tree, the competition intensity of intra-species was larger than that of inter-species, and reached the maximum at diameter at breast height (DBH) of 15-20 cm. It was predicted by power function that the intra-specific and inter-specific competition intensity of H. mollis would tend to be stable at DBH more than 22.5 cm. Therefore, shrub species should be chosen as main accompanying species in the management of H. mollis plantations, and small arbor with strong sprouting ability should be avoided.
Key words:  Hamamelis mollis  Population  Niche  Competition model for individual tree
