| Good plant landscape is a symbol to show the cultural ethos of an area.As the regional culture carrier the native plants shoud be protected and used well.Based on the biodiversity protection,26 sample plots,78 quadrats were set up to survey the wild ground covers in The Summer Palace and Chinese Academy of Forestry during spring,summer and autumn.The structure and differance of the phytocoenoses were studied by analyzed the species composition,the plant areal-types,biodiversity index in an objective way.The protection strategies and using types of the wild ground covers were drawn by the reseach of The Beijing Olympic Forest Park and The Baiwang Park.The result showed the rich plant resouces in The Summer Palace and Chinese Academy of Forestry which included 34 families 80 genera 88 species and 32 families 80 genera 93 species.The dominant families were Compositae,Gramineae,Leguminosae.The plant areal-types had little differance bettwen two sample areas which were simple in family areal-types and diverse in genus areal-types.The Cosmopolitan inculed the richest families and genera while the Temperate element were scarce.On the whole complicated stuctures composed of arbor,brush,grass were more diverse than the stuctures composed of arbor,grass in The Summer Palace.The communities had anthropogenic inferance were more diverse than the no artificial communities and artificial communities in Chinese Academy of Forestry.The seasonal aspect of the wild ground covers of the two sample areas was obvious during spring,summer and autumn.The dominant species were different between different seasons.The plant biodiversity of the wild ground covers were abundant in The Summer Palace and Chinese Academy of Forestry which were the typical park greenland and accessory greenland.The more scientific research was enhanced the better the wild ground covers be protected and used.An excellent project shoud have both scientificity and artistry. |
