林冠开度的变化影响下面的幼苗的生长和存活，因此在希望用有价值的木材物种在采伐后重新造林时具有实际重要性。本研究利用地统计学方法，对婆罗洲低地次生林中龙脑香苗木的生长和光环境进行了分析，以确定树冠开度与苗木生长之间的空间关系。幼苗生长与冠层开放措施，沿着种植线，但不相关的种植线，因为种植线之间的茂密的林下阻挡侧光。建议以斑块的形式种植，而不是沿着线种植，这样林下间隙可以让来自各个方向的树冠间隙的光线到达幼苗。
Variation in forest canopy openness influences the growth and survival of seedlings below, and is therefore of practical importance when wishing to restock a forest with valuable timber species after logging. In this study, growth and light environment of dipterocarp seedlings in an enrichment planting project in secondary lowland forest in Borneo were analysed using geostatistics, in order to determine the spatial relationships between canopy openness and seedling performance. Seedling growth was correlated with canopy openness measures up to 50m away along planting lines but was uncorrelated across planting lines, because the dense understorey between planting lines blocked lateral light. It is recommended that planting be conducted in patches rather than along lines, so that understorey clearance can allow light from canopy gaps in all directions to reach seedlings.
