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 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.
