武昌珞珈山植被及其演替研究 Ⅰ.植被现状

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

  • 摘要: 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。

     

    Abstract: 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 hm2), Pinus taeda+Cinnamomum camphora Form.(5.479 hm2), Quercus spp.Form.(2.711 hm2 )and Glyptostrobus pensilis+Metasequoia glyptostroboides+Taxodium ascendes Form.(2.410 hm2 )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.
