摘  要:
通过分析解析木研究彰武小钻杨生长规律与固碳释氧效益,结果表明:彰武小钻杨2~10年胸径生长较快;树高速生期从幼龄林阶段开始一直到16年时结束,以后生长缓慢;材积生长4年时开始进入速生期,速生期维持20年左右;幼龄林时年均固碳释氧能力很低,近熟林时年均固碳量和释氧量分别为6 025.0kg!hm-2和4 398.6kg!hm-2,固碳释氧能力较强。

摘  要:
Growth rhythm and benefit of carbon fixation &oxygen release of Populus×Xiaozhuanica were studied by analyzing stem analysis.Result shows that the DBH of Populus×Xiaozhuanicais quick from two to ten years;fast-growing period of height growth for Populus×Xiaozhuanicais from young growth to 16-year-old,slow growth in the future;began to enter the fast-growing period while the volume growth is four years and the fast-growing period can maintain about 20years;the annual capability of carbon fixation and oxygen releas per year is very low;the annual carbon sequestration and oxygen release of the near-mature forest for Populus×Xiaozhuanica per year is6 025.0kg!hm-2 and 4 398.6kg!hm-2 respectively y to release oxygen sequestration.
