摘要：分析了广东黑石顶自然保护区南亚热带常绿阔叶林林隙的形成方式及其特征．结果表明，在南亚热带常绿阔叶林中，由树木折干形成的林隙最为普遍，占５１．８６％，其次是由于掘根风倒而形成的，占３８．９８％．林隙大多由两株树木形成，平均每个林隙拥有形成木２．６３株．扩展林隙的大小多在１００～３００ｍ２之间，其中以２００～３００ｍ２者所占的面积比例最大，而以１００～２００ｍ２者所占的数量比例最大．冠空隙的大小多在１００ｍ２以下，其中以５０～１００ｍ２所占面积比例最大，而以５０ｍ２以下的所占数量比例最大．大部分林隙是在大约４０年前形成的，其中以１０年前形成的林隙最多．林隙形成木分布最多的径级在２０～３０ｃｍ之间，高度在２０～３０ｍ之间．每株形成木所能形成的扩展林隙面积为７２．９４ｍ２，冠空隙面积为２５．０６ｍ２．
This paper analyzed the manners of gap formation and the characteristics of gaps in the south subtropical evergreen broadleaved forest in Heishiding Reserve of Guangdong Province. The results showed that the most popular manner of gap formation in the forest was stem breakage (51.86% of the total), and the second, uprooting(39.98%). Most gaps were formed by two trees, averaging 2.63 trees per gap. The size of most expanded gaps was in the range of 100～300m 2, the gaps of 200～300m 2 occupied the biggest percentage in area, and those of 100～200m 2 occupied the biggest percentage in number. The size of most canopy gaps was under 100m 2, the gaps of 50～100m 2 had the biggest percentage in area, and those of <50m 2 had the biggest percentage in number. Most of the gaps were formed 40 years ago, and less than 10 years were the most. The diameter at breast height of most gap makers was 20～30cm,and their height were 20～30m. The average area of expanded gap and canopy gap formed by one gap maker was 72.94m 2 and 25.06m 2, respectively.
