Studies on Intra-and Inter-specific Competition of Hamamelis mollis
摘要
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.关键词
