| 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50.41%、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. |

| Abstract: | 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 felling,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. |
