| Abstract: | 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. |
