摘  要:
在木荷人工林天然更新形成的多代林中,对林缘、林边、林内、林隙的木荷种群的年龄结构和各龄级的空间分布格局进行研究,结果表明:林缘的龄级结构为增长型,与天然种群相似;林边、林内、林隙的年龄结构则呈梭形,种群处于较稳定的时期。林隙的中树分布呈均匀型,表明木荷种群的早期更新受到人工造林的影响;其他各龄级均呈聚集型分布,但聚集强度小于天然种群。

摘  要:
The age structures and the spatial distribution patterns of each age classes of populations in the edge,margin,inside and gap of Schima superba multi-generational forest as a result of natural regeneration originated from the artificial plantations were analyzed.The results showed that the structure of the populations in the forest edge was growth type,similar to that of natural population;The age structures of the populations in the margin,inside and gap of Schima superba planted forest were spindle-shaped,the populations were in the relatively stable period.The medium class trees distributed evenly in forest gap,which meant that the early regeneration of Schima superba was effected by the artificial afforestation.The other tree classes showed aggregated distribution pattern with smaller aggregation intensity than that of natural populations.
