摘    要:对闽北森林群落中的栲树(Castanopsisfargesi)和木荷(Schimasuperba)种群的数量特征和等级度结构分析表明:栲树和木荷均是闽北阔叶林迹地上的建群种群。中等强度的人为干扰可促进栲树种群发展,缺乏干扰或强烈的人为干扰均产生抑制作用。木荷种群在受自然干扰的森林群落中相对稳定,重要值和高等级度比例增加,而人为干扰使木荷种群减小,低等级度比例增加。人为干扰强度越大,木荷种群越难以发展。

关 键 词:栲树  木荷  干扰  种群  闽北

Abstract:The quantitative characteristics and size class of populations of Castanopsis fargesii and Schima superba in northern Fujian province were analyzed in this paper.The results indicate that both of them were Pioneer populations in the area where disturbance by human beings took place in evergreen broad leaved forests.The disturbance of medium level by human being might enhance the development of C.fargesii population.,while,both lack of disturbance and strong, frequent human disturbance would limit the developmentof C.fargesii population.The S.superba population kept relatively steady in communities under natural disturbance,and its important value and proportion of higher size class increased.Disturbance by human beings restricted S.superba population and increased the proportion of lower size class. The more frequent disturbance by human occurred,the more difficultly S.superba population developed.
Keywords:Castanopsis fargesii  Schima superba    Population  Disturbance  Northern Fujian province
