Research On The Plant Landscape Of City Parks In Hangzhou

Urban parks can reflect the level of urban landscape construction and the quality of life of residents.The city park of the West Lake in Hangzhou has become famous with unique landscape at home and abroad.This paper choosed Liulangwenying Park of Hangzhou as the researching object,and analyzed the species of plant community composition,plant community structure,species diversity of plant community,plant space structure,plant culture and so on.The main conclusions are as follows:(1)There were 155 species of plants in Liulangwenying which belonged to 68 families and 128 genera.including 6 families,9 genera,11 species of gymnosperm and 62 families,119 genera,144 species of angiosperm.The arbor,shrub,herb,liana accounted for the total number of plant species in the park 37.42%,29.68%,28.39% and 4.51% respectively.Evergreen and deciduous tree species was 1:1.4.The tree layer importance value was ranked in the top ten of metasequoia ?osmanthus ?willow ? pterocarya ? sycamore ? magnolia grandiflora ? camphor ? ginkgo biloba ? phoebe sheareri?prunus lannesiana,about shrub layer,species important value of the top ten in turn was malus halliana?fatsia japonica?crape myrtle ?acer palmatum ?red maple ?spring cuckoo ?loropetalum?phnom penh boxwood?camellia?camellia.(2)Plant community of Liulangwenying was mainly divided into 5 vegetation types,10 life forms and 19 types of buildings.The arbor,Shrub and grass collocation were the main way to building the park plant community landscape.Average Margalef richness index of the plant community was 0.858,average Simpson dominance index was 0.464,Shannon-weiner diversity index averaged 0.905,average Pielou evenness index was 0.599.The diversity index of tree layer,shrub layer and herb layer was found in the tree layer > shrub layer > herb layer.The species diversity of tree layer was the highest.The survey of plant diversity in the scenic spot found that the species diversity of the park was higher than that of the other three scenic spots.(3)The basis of a survey about the plant communities of the Liulangwenying,there was a detailed analysis of the plants and buildings,roads,water,sketches and other elements of the garden landscape space,analysising and summarizing the park plant landscape space type from space-forming elements.(4)Through preliminary research of plant culture of Liulangwenying Park,plant culture is mainly reflected in the species selection,configuration mode,poetry and so on.Proposing the Cultural Festival with the "willow" as the theme in the park,highlighting the theme.(5)Summarized Liulangwenying landscape characteristics and existing problems,and gave suggestions.
