摘　　要：通过桉树林景观改造工程建设中引入树种筛选,采伐强度2个因子,开展了红锥、木荷、樟树、乐昌含笑、灰木莲等5个树种成长测定,结果表明:树木高度的大小为红锥>樟树>灰木莲>木荷>乐昌含笑;地径的大小为红锥>木荷>樟树>灰木莲>乐昌含笑;冠幅的大小为红锥>木荷>樟树>乐昌含笑>灰木莲。总体来,红锥生长效果最好,其他树种的生长情况与和其他文献较为接近。研究了林下多样性变化情况,发现桉树林全部采伐后物种的数量达到最大。更新层、灌木层、草本层、藤本新的物种的进入也更为频繁,证明林相改造达到了预期的效果。In this paper,through the introduction of tree species screening and cutting intensity in the construction of Eucalyptus forest landscape reconstruction project,the growth of five tree species such as Castanopsis hystrix Miq.,Schima superba,Cinnamomum Camphora(L.)Presl.,Michelia chapensis Dandy and Magnoliaceae glanca Blume was measured.The order of tree height was Castanopsis hystrix Miq.>Cinnamomum Camphora(L.)Presl.>Magnoliaceae glanca Blume>Schima superba>Michelia chapensis Dandy.The order of ground diameter is Castanopsis hystrix Miq.>Schima superba>Cinnamomum Camphora(L.)Presl.>Magnoliaceae glanca Blume>Michelia chapensis Dandy.The order of crown width was Castanopsis hystrix Miq.>Schima superba>Cinnamomum Camphora(L.)Presl.>Michelia chapensis Dandy>Magnoliaceae glanca Blume.Overall,the growth effect of Castanopsis hystrix Miq.is the best,and the growth of other species is close to other literature.The change of understory diversity was studied,and it was found that the number of species in Eucalyptus forest reached the maximum after all felling.New species entering the regeneration layer,shrub layer,herb layer and vine layer are also more frequent,which proves that forest facies transformation has achieved the expected effect.
