Study On The Landscape Characteristics Of Plants In Hangzhou

At present,the hangzhou has entered a new historical stage,enrich the connotation of the beautiful countryside construction,improve level,how to improve rural plant landscape beauty,rural landscape culture differentiation,create suitable for living,business and travel of village plant landscape,is the current rural plant landscape construction problems had to be taken into account.In this study,13 natural villages or village groups under 3 traditional and 3 modern administrative villages were investigated on the spot,through the calculation of the tridimensional green biomass,green contribution rate,green contribution rate and other plant landscape indexes,relative frequency,relative density,relative coverage,important value and other plant characteristic indexes of each plant landscape type in each village,combined with the typical sample plots surveying and mapping,summarizes the characteristics of rural landscape plant of hangzhou,the plant landscape of different villages’ commonalities and differences,differences and influencing factors of plant landscape characteristics of public recreation green space in different villages.Based on the results it is concluded that the relevant conclusions and suggestions,for providing the basis and reference for the continuation and protection of rural characteristic landscape in hangzhou and the construction and renewal of plant landscape of rural public recreation green space.The main research results are as follows:I.Characteristics of rural plant landscape in hangzhou:(1)Relying on its own advantageous industries,each village has formed its own characteristic surrounding village landscape and productive landscape,and based on this as the ecological base,combining with the construction of characteristic plant landscape in the village,it has formed an era characteristic rural appearance of integrated development of production,ecology and life.However,whether it is the renewal and regeneration of traditional rural landscape or the reconstruction and addition of modern rural landscape,the phenomenon that the regional and humanistic features of landscape gradually weaken in the process of construction by imitating the urban landscape design technique.(2)Summary of characteristics of different plant landscape types: Production land education interaction,colorful ecological;The entrance green space has bright theme and rich colors;The courtyard green space flowers fragrance,full of green;The public recreation green space is profound,open and harmonious;Waterside green land bamboo cluster,wild natural;Road green space trees big shade thick,strong countryside.(3)The function of plant landscape has changed from shading,sun avoidance and environmental protection in the early stage to multiple functions such as ecological protection,village appearance improvement,space creation and cultural communication,showing a general trend of "transformation from single function to compound function".II.Common characteristics and differences of two types rural plant landscapes:(1)The first two plant landscape types with the highest green contribution rate of the two village types are public recreation green space and road green space.The courtyard green space has the highest diversity of plant species.The proportion of arbor in the two types of rural plant landscape decreased,and the overall plant landscape in the village tended to be shrubby and miniaturized,which was more obvious in the green space at the entrance of the village and the green space in the courtyard.(2)The proportion of ornamental plants in the landscape of the two village types was the highest.In the traditional courtyard green space,the proportion of economic edible plant species is higher than that of the modern type.The proportion of plant functions in the landscape types of plants in traditional village tends to be the proportion of plant species in geomantic and cultural type > ecological and protection type,while the proportion of plant species in modern village tends to be the opposite,the proportion of plant species in ecological and protection type > geomantic and cultural type.(3)On the basis of continuing the traditional landscape style of fruit trees and local tree species,the modern rural plant landscape adds a lot of middle and lower class flower and leaf plants,making the overall plant landscape more diversified and urbanized.Especially in the public recreation green space.(4)Waterfront green space and public recreation green space are the main sources of green quantity in traditional villages.Road green space is the main source of greenquantity in modern villages.III.Differences in plant landscape characteristics of two types of rural public recreation green space:(1)There were 138 species of plants of 108 genera and 61 families in the three traditional villages,and 143 species of plants of 110 genera and 64 families in the three modern villages.Taxaceae、Juglandaceae、Pinaceae are not used in the modern villages’ public recreational green space.(2)The specific value of arbor and shrubs in modern villages is 1:100,which is lower than 3:100 in traditional villages.The proportion of deciduous species was greater than that of evergreen in the layers of modern villages arbor,but generally speaking,the number of evergreen species was greater than that of deciduous species in both types of villages.(3)Rhododendron simsii,Photinia x fraseri,Camellia sasanqua,Nandina domestica,and other 11 main dominant plants appear stably in both types of villages.Ginkgo biloba,Zelkova serrata in a marked increase in the modern village of important values compared with traditional,Osmanthus fragrans,Nandina domesticasouth in the modern village important value than traditional has increased,the important value of Camellia sasanqua in modern village is lower than that of traditional village.(4)The per capita green space area of traditional rural village recreation green space is 4.2m2,and that of modern village is 8.09m2.From traditional to modern rural area,the per capita green space area shows a significant trend of increase,but the plant size tends to be smaller.The high proportion of shrub population is more obvious in modern villages.(5)Compared with the modern type,the plant landscape of the traditional type of public recreation green space is more cultural.Most of the beautiful countryside construction is guided by the improvement of green rate and village style,blindly following the urban green mode and lacking the depth of local culture excavation,which are the leading factors for the change of the plant characteristics of the rural public recreation green space.
