常绿阔叶林主要建群树种林木生长规律的研究

Study on the Growth Regularity of the Dominant Species of Evergreen Broad-leaved Forest

常绿阔叶林是江西省地带性植被类型。本文分析赣南建群树种有丝栗栲、南岭栲、米槠、木荷、黧蒴栲,而赣东北为甜槠、木荷、丝栗栲、石栎。利用标准地平均木的解析资料,建立林木树高、胸径、材积潜在的生长量函数。拟合结果以理查兹曲线拟合效果最好,相关系数均大于0.9。

Evergreen broad-leaved forest is a typical of vegetation in the Jiangxi province. This paper made an analysis of dominant trees in the southeastern Jiangxi which were Castanopsis fargesii, C. carlesii, Schima superba, C. fissa and in the northern Jiangxi which were C. eyrei, S. superba, C. fargesii, Lithocarpus glaber. On the basis of the stem analysis data in plots, regression models of stem volume, DBH and tree height were established. The fitting Richards curve effect was better,the linear correlation coefficient was higher than 0.9.
