长白山阔叶红松林3个常见树种径向生长的影响因素
Factors influencing tree radial growth of three common species in broad-leaved Korean pine mixed forests in Changbai Mountains, China
摘要
Abstract
To understand the factors influencing tree radial growth,we analyzed the seasonal dynamics of tree growth of 3 common species (Pinus koraiensis,Tilia amurensis,Quercus mongolica),compared interspecific growth rates and explored the effects of size,neighborhood competition,soil and topography based on five years dendrometer bands monitoring data of the 3 common species in a broad-leaved Korean pine (P.koraiensis) mixed forest plot in Changbai Mountain,Northeast China.The results showed that the growth dynamics of 3 species were consistent.Trees began to grow in late May,thrived in July,grew at declining rates from late August and stopped growing in late October.Annual relative growth rates were significantly different among the species.Q.mongolica tended to grow faster than the other two species,and the differences of growth rates among the 3 species were especially large for small and medium trees.Tree growth rates of P.koraiensis and Q.mongolica were strongly decreased by neighborhood competition,while tree growth rate of T.amurensis was significantly related to tree size,soil and topography.关键词
