【摘要】 依据所设固定样地的观测资料,研究了炼山与未炼山两种林地清理方式对2年生巨尾桉人工林林木生长量及其林下灌草层植物种类组成的影响。研究结果表明:两种林地清理方式的2年生巨尾桉人工林林木生长量差异不显著;林分郁闭前,2年生巨尾桉人工林群落的灌草层植物物种丰富度炼山清理的低于未炼山清理的,但炼山清理有利于灌草类植物在巨尾桉人工林幼林期的迁入与定居。更多还原

【Abstract】 The effects of two ways of clearing,with and without burning of debris under two year old of Eucalyptus robusta artificial forest,on the trees’mass growth and plant diversity within it were investigated.It showed that there was not significant difference in growth mass for the two ways of clearing;and before the closure of the stand,the plant diversity of the former was less than that of the later.Nevertheless,this burning was beneficial for the colonization of the seedlings of Eucalyptus robusta in bush and tussock fields.更多还原
