| 摘 要： | 对内蒙古准格尔黄土丘陵沟壑区天然杜松疏林进行了林分胸径、株高、密度和群落结构等的调查.结果表明:发育良好的杜松疏林具有明显的乔木层、灌木层和草本层,如杜松-虎榛子-日阴菅群落、杜松-黄刺玫-日阴菅群落、杜松-黄刺玫-黄囊苔群落;若干扰进一步减弱,它们会演替为辽东栎+杜松或油松+杜松群落;若干扰加强,杜松疏林会逆向演替为灌丛或草原,甚至为裸沟坡地.杜松疏林有高的物种丰富度,但生境脆弱,且林分平均胸径、平均高、密度均较小,故不适合作为用材林,应作为水土保持林和种源林加以保护利用更为合理.

| Abstract: | The breast diameter,height,plant number and community structure of Juniperus rigida open forest,distributed in Junger loess hill-gully region of Inner Mongolia were investigated by quadrat method.The result shows that J.rigida open forest has obvious tree,shrub and herb layers,such as the Ass.J.rigida-Ostryopsis davidiana-Carex pediformis,Ass.J.rigida-Rosa xanthina-C.pediformis,Ass.J.rigida-R.xanthina-C.korshinskyi.If the habitat keeps stable continuously,it will be replaced by Ass.Quercus liaotungensis+J.r... |
