| Abstract: | Taking Damushan National Reserve Forest in Tongshan County as the research object,20 permanent plots were set up for monitoring impacts of future-crop-tree management(FCT management)on forests of Cunninghamia lanceolate and Sassafras tzumu.The plots were established according to thinning intensity of stand volume:comparative plot(0%),low intensity(15.7%),medium intensity(27.0%),high intensity(36%)and very high intensity(45.6%).The monitoring results in thinned plots after 1 year showed that in comparison with those in 2019,the average DBH of FCT in the plots has increased 0.52 cm·a-1 and the unit volume has increased 4.38m3/hm2·a.Meanwhile,in the plots with different thinning intensity,on average 6.25 kinds of species and 21 new seedlings appeared per 100 m2;in the comparative plots,only 3 kinds of species and 12 new seedlings were found,respectively.Obviously,FCT management can not only promote the tree growth and increase the stand volume,but also improve vegetation regeneration under trees and increase species diversity,which provides strong support for selection of treatments of National Reserve Forests project. |
