摘　　要：本文根据多点密度试验林的长期观测资料,对黑杨派南方型杨树密度效应规律进行了系统研究。内容包括造林密度与树冠结构、造林密度与林木生长特性、造林密度与生物量等关系的研究。According to the investigated data from various man-made density experimental forests in China, the authors have systematically studied the density effect of man-made southern type poplar forests. The studied items include the relationship between planting density and crown structure, planting density and growth characteristics, planting density and biomass etc.
