武昌珞珈山植被及其演替研究Ⅰ.植被现状

在对武汉大学校园所在地武昌珞珈山全面踏勘的基础上，绘制了该区域的植被图，并将珞珈山植被划分为６植被型组１０植被型２０群系。通过对其中９个主要群落类型１２个样地的样方调查，得到了有关群落结构的基本资料。结果表明，武昌珞珈山的植被性质为人工次生植被，其主体是小叶栎＋樟林（面积１８．１８７ｈｍ２）、火炬松＋樟林（５．４７９ｈｍ２）、锐齿槲栎＋槲栎林（２．７１１ｈｍ２）和水松＋水杉＋池杉林（２．４１０ｈｍ２），四者共占校园面积的２１．４５％。２０群系中９个群系的建群种可自然更新。

STUDY ON VEGETATION AND ITS SUCCESSION ON LOUJIA HILL,WUCHANG,WUHAN Ⅰ.STATUS QUO OF VEGETATION

Based on an overall survey of Luojia Hill,located at the Wuhan University,the vegetation there was mapped.It was divided into 6 vegetation type groups,10 vegetation types and 20 formations.Furthermore,twelve standard quadrates of nine formations were sampled,and the data on the community structures were obtained. We concluded that the vegetation of Loujia Hill belongs to artificial one; Quercus chenii Cinnamomum camphora Form.(with a square of 18.187 hm 2), Pinus taeda Cinnamomum camphora Form.(5 479 hm 2), Quercus spp.Form.(2 711 hm 2 )and Glyptostrobus pensilis Metasequoia glyptostroboides Taxodium ascendes Form.(2 410 hm 2 )are the main body of the vegetation,covering 21.45% of the campus of Wuhan University;constructive species in nine of 20 formations could regenerate naturally.
