摘　　要：利用47年生马尾松成熟林,分别对3个径级组的产脂量和3个不同密度未采脂林的生长量进行了研究。结果表明:随着密度增加,胸径、树高和材积年均增量皆呈减少趋势,但差异不显著;随着径级组增加,单日产脂量、产脂力和矫正产脂力呈增大趋势,且差异皆显著;采脂林与未采脂林比较,生长量差异皆显著,说明采脂对生长有较大负向影响。综合分析采脂与木材收益,可知采脂林总体收益更高。本研究可为马尾松大径材林的定向培育提供技术支撑。Using 47 years old mature forests of Masson pine （ Pinus massoninana） in, resin traits of 3 diameter groups and growth traits of 3 different densities no-tapping forests were studied separately. The results showed that ： as the density increased, DBH, tree height and volume of annual increment decreased, but there were no significant difference ; as the diameter group increased, single-day resin yield, resin productivity and rectification resin productivity had a trend of increase, but there were all significant differences;there was highly significant differences for growth between tapping forests and no-tapping forests, so tapping resin had the significant negative effect to growth. With the comprehensive analysis for gains of timber and resin, the tapping forests had better economic gains. The research can provide the technical support for larger diameter timber forest of Masson pine.
