Intraspecific and interspecific competition in Liquidambar formosana on Mount Tianmu
摘要
Abstract
Field data from 145 Liquidambar formosana target trees and 614 individuals of competing species in the National Nature Rreserve of Mount Tianmu were quantitatively analyzed using the Hegyi competition index model for single-tree intraspecific and interspecific competition intensities. Results showed that competition intensity decreased gradually with an increase in tree diameter class. The order of intraspecific and interspecific competition intensity was as follows: Pinus massoniana > Liguidambar formosana > Cunninghamia lanceolata > Albizia macrophylla ^ Quercus acutissima > Quercus fabri > Castanopsis sclerophylla > Lithocarpus brevicaudatus > Castanea henryi > Platycarya strobilacea > Quercus chenii > Phoebe sheareri > Loropetalum chinense > Mallotus philippensis ~> Schima superba > Pistacia chinensis > Symplocos sumuntia. The competition index (Ic) and diameter at breast height (DBH) of the objective tree were related. Also, when the DBH of Liquidambar formosana reached 30 cm, the competition intensity became very small. Simulating and predicting competition intensity of the Liquidambar formosana community suggested Hegyi's competition model for individual trees could supply a quantitative index for study on intraspecific and interspecific relationships in plant population ecology and provide a reliable basis for the operation and management of the National Nature Rreserve of Mount Tianmu.关键词
