| 摘 要： | 从林隙大小结构、形成方式及形成木数量特征等方面，对南方铁杉林隙干扰状况进行对比研究。结果表明：林冠空隙（CG）主要集中在400m^2以下，扩展空隙（EG）主要集中在700m^2以下；林隙形成木以枯立木和风倒木为主，形成木高度集中在20～60m，形成木树种组成与其主林层树种所占比例相对应。 |

| Abstract: | A comparative study was made on the gap size, structure, formation, number of gap-markers and other characteristics to explore the gap disturbance to Tsuga chekiangensis forest status. The results indicted that the size of most canopy gaps（CG） was smaller than 400 m^2, and the size of most extended gaps （EG） was smaller than 700 m^2, respectively. Most gap makers of T. chekiangensis forest were snags and fallen dead woods, and the height of most gap makers ranged from 20 to 60 m. The species composition of the gap makers was similar with the species composition of the main arbor storey of the forest. |
