摘　　要：文章研究了不同间伐强度与株数的变化情况和间伐强度与径阶蓄积的变化,并根据不同间伐强度研究了枯落物存量变化。结果显示:中度间伐强度效果明显好于轻度间伐和重度间伐,分别比不间伐林分蓄积量提高7.65%、28.63%和10.39%。The changes of the different thinning intensities,numbers of trees,harvesting intensities,diameter accu-mulated were studied.Changes of litter were also studied according to different thinning intensities.Result shows that the result by adopting moderate thinning intensity is significant optimal than that by adopting mild and severe thinning intensity,which increase by 7.65%,28.63% & 10.39% than that of the CK.
