摘要：基于林分树干解析资料,对广西大青山27年生红椎人工林的生长规律进行分析研究,结果表明:(1)7～12年为胸径连年生长量的速生期,第8年胸径连年生长量达峰值,第11年后连年生长量略呈下降趋势,但连年生长量与平均生长量曲线直到22～23年才相交;(2)4～11年为树高连年生长量快速增长期,树高连年生长量于第7、8年达峰值,随后开始逐渐下降,并在第12年与树高平均生长量相交;(3)11～27年材积生长一直处于不断增长的阶段,直到27年生时,材积生长量仍未达数量成熟,红椎人工林材积的生长潜力大;(4)利用Richards方程拟合红椎人工林胸径、树高和材积的生长规律,拟合优度均在0.99以上,拟合效果显著。
Based on the material of stem analysis, the growth regularity of Castanpsis hystrix A.DC plantation in Daqingshan was analyzed. The results show that （1） the fast-growing period of annual increment of DBH was from the 7th year to the 12nd year, the growth of annual increment of DBH reached the peak in the 8th year, it declined slightly after llth years, but the curve of annual increment of DBH and the curve of average growth didn＇t intersect until the 22nd - 23rd years. （2） the fast growing period of annual increment of tree height was during the 4th - 11 st years, and the annual increment of tree height reached the peak in the 7th and 8th years, after that it gradually decreased, and it intersected with the curve of average growth of tree height in the 12nd years. （3） the fast growing period of volume was during the 11st - 27th years, and until the 27th year, the growth of volume hadn＇t reached the quantitative maturity, the growth of Castanpsis hystrix A. DC plantation volume had a great potential. （4） the Richards equation was good to mode the growth regularity of DBH, tree height and volume of Castanpsis hystrix plantation, the goodness of fit were more than 0.99, fitting effect was obvious.
