| 摘 要： | 以大青杨(Populus ussuriensis)人工林为研究对象,采用生长轮材质分析法研究了初植密度对木材显微构造特征和固碳量的影响。研究结果表明,4.0 m×4.0 m初植密度可作为短期轮伐林的培育模式,以获得大径级的相对优质人工林大青杨木材;2.0 m×2.0 m初植密度可作为长期固碳林的培育模式,且由于其具有相对较优的木纤维微观构造特征参数,采伐后的大青杨木材可作为造纸原料使用。

| Abstract: | A study was performed to discuss the effects of planting density on wood microstructure characteristics and carbon storage of Populus ussuriensis by analyzing wood quality in growth rings.Results showed that the planting density of 4.0 m×4.0 m could be used as the optimal cultivation mode for short-rotation plantation to get large-sized timber with relatively high wood quality.Meanwhile,the planting density of 2.0 m×2.0 m was proposed as the cultivation mode for carbon sink plantations,and the logged timber could be used as paper making material due to its relatively good microstructure characteristics of xylon. |
