| 摘 要： | 以38年生江南油杉人工林为研究对象，探讨抚育间伐对其林木胸径、树高和单株材积生长的影响。结果表明，1~3 a为江南油杉胸径和树高生长缓慢期，4~18 a为其速生期；抚育间伐对江南油杉林分胸径、单株材积生长具有明显的促进作用，对处于生长旺盛期的树高生长影响显著，但其后期对树高生长的作用不大；材积连年生长量和平均生长量曲线在38 a时未相交，表明其材积生长尚未达到数量成熟。建议继续加强该江南油杉林分的抚育管理，采取及时合理的间伐措施，以期实现江南油杉人工林优质大径材的高效培育。

| Abstract: | Taking the 38-year-old Keteleeria cyclolepis plantation as the research object,the effects of tending thinning on the growth of diameter at breast height (DBH),height and individual volume growth were studied.The results showed that 1-3-year was the slow growth period of DBH and tree height,and 4-18-year was the fast growth period.Tending thinning had an obvious promoting effect on the growth of DBH and individual volume,and had a significant effect on the height growth in the fast growth period,but had little effect on height growth in the later period.The curve of continuous annual volume growth and average volume growth did not intersect in the year of 38 indicating that the volume growth had not reached quantitative maturity.We suggested the K.cyclolepis stand should be further managed and reasonable thinning measures should be taken in time to achieve efficient cultivation of high-quality and large-diameter timber. |
