The results showed that small-scale gaps were the predominant types of disturbance. The average gap density was 12.5 km^(-1). The distribution pattern of gaps was aggregated on south facing slopes and was approximately homogeneous on north facing slopes. Conifer trees were the primary gap-makers in this forest that was dominated by Abies faxoniana, Tsuga chinensis, Betida utilis, both in abundance and diameter rank. The decay class distribution of gap-makers indicated that the mode of gap formation and gap-maker species changed with age of the forest; the contribution of conifer species to gap formation decreased with time and broadleaf species increased.

结果表明：l本区以小型林隙干扰为主，林隙平均密度为12.5个km^(-1)，林隙的分布格局在阳坡和山脊为集聚分布，阴坡近均匀分布；林隙形成木以针叶树为主，岷江冷杉、铁杉和糙皮桦在形成木的数量和径级组成上均居前列。2林隙形成木的腐烂等级分布揭示出林隙形成木的形成方式和种类组成均随时间变化。
