幼苗期是树木生命周期中的关键阶段，其表现受非生物和生物因素的控制，这些因素在空间上是异质的。本文研究了矮秆竹密度、坡角、地形凸度、距最近的同种成竹的距离、F. crenata幼苗，幼苗大小和年龄），在考虑的方向和强度的变化的微地形效应跨越空间。2011年，我们鉴定了所有F. crenata幼苗（最大茎长
The seedling stage is critical in the life cycle of trees, and performance is controlled by both abiotic and biotic factors, which are spatially heterogeneous. We investigated the relationships between the seedling survival or growth of Fagus crenata and seven potentially influencing factors (culm density of dwarf bamboo, slope angle, topographic convexity, distance from the nearest conspecific adult, and local density of F. crenata seedlings, and seedling size and age), under consideration of the changes in direction and strength of the microtopographic effects across space. In 2011, we identified all F. crenata seedlings (maximum stem length
