摘　　要：对广西高峰林场第二代尾叶桉林进行炼山与不炼山生长比较研究.结果表明:不炼山样地的尾叶桉树高与胸径生长均优于炼山样地的,不炼山的尾叶桉蓄积生长迅速,是同期炼山样地的2倍以上.炼山后造成地表覆盖物的销毁,枯落有机物和养分库大量损失,增大了幼林地的水土流失,不利于幼林的生长.Growth of the second generation E.urophylla between burning and non burning at Gaofeng forest farm of Guangxi has been compared.The results showed that the height and DBH of E.urophylla in non-burning plot were better than burning plot.The stock volume of E.urophylla in non-burning plot increases rapidly,which is more than two times as much as that of the burning plot in the same period.Meanwhile,some side effects occurred in burning plots such as vegetation destruction,significant loss of organic litter and nutrients,increased soil erosion in the young forest which is not conducive to the growth of young forest

关 键 词：尾叶桉萌芽林 炼山 生长比较 蓄积生长
