中文摘要：
对福建省南平市峡阳国有林场29年生的1代杉木人工林的采伐剩余物长期分解速率进行研究．结果表明：采伐后16个月总剩余物的分解率为50．03％，而枝的分解率仅为28．79％；采伐后32、36、44、56、72、84个月时总残留率分别是33．89％、30．08％、23．72％、13．65％、10．35％和8．74％，而枝的残留率分别是50．4l％、44．74％、35．28％、20．30％、15．40％和12．99％．随着时间的推移，总采伐剩余物的分解速率与枝的分解速率有渐趋减小的趋势．
英文摘要：
In the first rotation stands of 29-year-old Chinese fir plantation in Xiayang State Forest Farm, Nanping, Fujian, the study on the decomposition rate of logging slash over a long period of time was made. The results showed that 16 months after feUing, total decomposition rate was 50.03% and branch decomposition rate was only 28.79%. Thirty-two, 36, 44, 56, 72 and 84 months after felling, total decomposition rate was 33. 89%, 30. 08%, 23.72%, 13. 65%, 10. 35% and 8. 74%, respectively, and branch decomposition rate was 50.41%, 44.74%, 35. 28%, 20. 30%, 15.40% and 12.99%, respectively. Along with the time, total decomposition rate and branch decomposition rate decreased gradually.
