Study On The Characteristics Of Garden Plant Community Of The Main Temple Garden In Chengdu

Temple garden is an important component of the Chinese classical landscape,with the development of the times,temples garden is a place not only a place of religious belief,but also tours and exchanges of public space,the specificity of the use of plants in the landscape at the time of the types of choices and plants disposition.On the basic of investigations of the present afforestation situation in five temple garden by taking of samples,the different greening patterna of the different greenlands are evaluated.And then community structures,landscape benefit and green quantity are evaluated.So the differences of the different greenlands in five temple garden In landscape benefit and ecological benefit are compared. Greening patterns of the different Greenlands in five temple garden are analysed and assessed.And the better greening pattern is summaried to support more scientific reference for planning and designs in the residential green space of Chengdu,and it is construetion and management.The main result is as follows:(1) Investigation shows that the species in five temple garden of Chengdu is relatively high,Which includes 73 speeies,46 families,37trees of all speeies 22 shrubberies of all speeics 6 ground cover plants of all species.8 kinds of categories of herbal flowers,vine general,the application of aquatic fewer flowers.The use of more types of plants is magnoliaceae,Rosaceae,Oleaceae,Lauraceae,these types of ornamental plants,and landscape plants is also strong shape.But the remaining 42 kinds the application of small plant species,only 1 species or 2.(2) Investigation shows that plant tree layer and shrub layer of diversity and evenness analysis of temple courtyards and gardens in each temple garden.In temple courtyards,the average scores of the tree species diversity between in 0.5～0.7,followed by Zhaojue temple,Daci temple,Qingyang temple, Wenshu temple,Baoguang temple,average species diversity of shrub layer in between 0.03～0.3,as follows:Daci temple,Qingyang temple,Zhaojue temple,Baoguan temple,Wen shu temple.in garden,the average species diversity of tree layer in between 0.7～0.8,as follows:Baoguangtemple,Daci temple, Wen shu temple,Zhaojue temple,Qing yang temple;shrub layer species diversity of the average in the 0.3～0.7 years,as follows:Daci temple,Baoguangtemple,Zhaojue temple,Wen shu temple,Qing yang temple.As can be seen from the pielou index:Temple Court,the tree layer species evenness average around 0.9,as follows:Qing yang temple,Baoguangtemple,Zhaojue temple,Daci temple,Wen shu temple;shrub layer in the mean species evenness between 0.5～0.07,as follows:Daci temple,Qing yang temple,Zhaojue temple,Baoguang temple,Wen shu temple;In garden,the tree layer species evennessbetween the average in the 0.8～0.9,followed by:Wen shu temple,Baoguangtemple,Daci temple,Zhaojue temple,Qing yang temple;shrub layer species evenness in an average of 0.5～0.9 years, as follows:Zhaojue temple,Daci temple,Baoguangtemple,Wen shu temple,Qing yang temple.(3) A modified plant landscape evaluation method named"AHP"modelwas used to assess greening pattern of five temple gardens.Assessment results show that:the five temple according marks from higher to lower are Bao guang temple,Wen shu temple.Qingyang temple,Daci temple,Zhaojue temple.At the same time,two kinds of temple greenlands ranked according the average mark from higher to lower is public gardens and roadside greening of temple.General mark for public greening is between 6.8 and 7.8.The public gardens according marks from higher to lower are Baoguang temple,Qingyang temple,Wenshu temple,Daci temple,Zhaojue temple.General mark for public greening is between 5.2 and 6.the roadside greening of temple from higher to lower are Daci temple,Wenshu temple,Qingyang Temple,Baoguang temple,Zhaojue temple.(4) Green quantity is calculated by the method that plane quantity simulates thre-dimensional quantity.The five temple gardens according general average marks of greenQuantity from higherto lower are Zhaojue temple,Daci temple,Qingyang temple,Baoguang temple,Wenshu temple.For public greenlands,the general average marks of green quantity from higher to lower are Zhao jue temple,Daci temple,Qingyang temple,Baoguang temple,Wenshu temple.For roadside greenlands,Wenshu temple, Zhaojue temple,Baoguang temple,Daci temple,Qingyang temple.The main cause different lies in plant species,planting structure.(5) By comparison and analyses of the different greening patterns of the different Greenlands that it is landscape and ecological benefit are higher,proportion of life from and community structures are analysed.In public garden greening,Suitable proprtion of life form for tree is2.5～3:1 for species, 2.75～3.5:1 for plant quantity,while the proportion for shrubbery is 2:1 for species,4.8～5.5:1for plant quantity.In roadside greening,Suitable proportion of life form for tree is 1:1 for species,1.6～1.63:1 for plant quantity,while the proportion for shrubbery is 1.5:1 for species,3.5:1 for plant quantity.In the two kinds of greenlands suitable proportion of life form between tree andshrubbery each is 2～2.25:1 for species,0.91～1.92:1 for for plant quantity,0.67～2:1 for species,1.1～2.5:1 for for plant quantity.
