摘要对象牙海岸泰国家公园热带湿润森林3个样地（共71 ha）的冠层间隙空间分布进行了分析。模式分析显示，三个站点中有两个站点的间隙呈聚类分布。林隙形成过程可能解释了林隙发生和分布的局部差异。林隙密度、大小和林隙期森林面积百分比在上、中坡均高于坡顶和坡底。结果表明，林隙依赖树种的更新可能指向干扰最大的连带位置。林隙依赖物种的空间分布具有聚集性，这不仅与林隙内部的更新有关，也与林隙本身的聚集性有关。
ABSTRACT The spatial distribution of canopy gaps was analysed on three sites (total 71 ha) in the tropical moist forest of Tai National Park, Ivory Coast. Pattern analysis revealed a clustered distribution of gaps for two of the three sites. Catena dependent gap formation processes might explain local differences in the occurrence and distribution of gaps. Gap densities, sizes and percentage forest area in gap phase are higher on the upper and middle slope than on the crest or lower slope. As a consequence, regeneration of gap dependent tree species might be directed to the catena positions with the highest disturbance regime. The spatial distribution of gap dependent species can be clumped, not only due to the regeneration within gaps, but also due to the clustered nature of gap distribution on its own.
