Study On Road Landscape Improvement Design In New Urban District

The new urban district is the functional extension and development of the main urban district.It is an important district to reshape the new image of the city and disperse the population of the main city.As one of the elements of urban image,roads can not only meet the traffic functions and connect various urban spaces,but also are important elements to shape the image of the new district,which most intuitively reflects the environmental quality and cultural style of the city.Based on the study of domestic and foreign urban planning,landscape architecture,plant landscape and other related disciplines theory,on the basis of reference to relevant cases of road landscape design practice,summarized the urban new district road landscape elements,design principles,design strategy,design methods,such as key points,form the theoretical basis of road landscape design research.Study selected the road landscape improvement design of the road of Advanced Business Park in Wuxiang new district as the object,and the results are as follows:(1)The road landscape evaluation system established by using the analytic hierarchy process,through the overall style,use function,culture and art,and ecological value,27 evaluation factors are screened,and 19 evaluation factors and their weights such as landscape style,structure positioning,and landscape space construction are finally formed.The fuzzy comprehensive evaluation method is used to analyze the current road landscape and sort out the existing problems.(2)In view of these problems,the design concept is proposed in the road landscape improvement design: to control the overall landscape style from a macro perspective,to clarify the primary and secondary of the road landscape structure and the type of the landscape interface along the line,to be harmonious with the surrounding architectural style and color as a whole,and to connect the road landscape plane layout with the external environment space of the surrounding block naturally,forming a harmonious and unified whole;At the micro level,it is necessary to adjust measures to local conditions,control the scale of the activity space in the green space according to the use function requirements,combine with the human visual experience,use various landscaping techniques,excavate the regional culture and the characteristics of the new urban district,and improve the green landscape,square pavement,facilities and other elements.(3)Through field investigation,the greening characteristics of the existing urban districts and surrounding provinces and cities in Nanning were investigated and analyzed.Adhering to the principle of "suitable for the place and trees",the SWOT analysis method was used to screen the greening plant species,including 36 greening plant species before promotion,91 greening plant species used in the promotion design,42 arbors,49 shrubs and ground covers,including 41 flower varieties,11 Leaf Varieties and 10 fruit varieties,The road greening landscape will be upgraded into a plant landscape with subtropical plant characteristics,continuing the keynote of "China Green City" in Nanning and highlighting the style of Wuxiang new district.(4)Excavate regional and national culture,refine and interpret elements such as Wuxiang,Zhuang brocade and bronze drum by using artistic abstract techniques,continue the unified style and color of Wuxiang new district,integrate it into the design of pavement and furniture sketches,and create a new urban landscape that reflects not only the image of "Zhuang township",but also modern and open temperament.(5)The fuzzy evaluation method is used to evaluate the road landscape of Wuxiang Advanced Business Park.The average comprehensive score of the current road landscape evaluation of the Advanced Business Park before upgrading is 48.54.According to the principle of maximum subordination,the landscape evaluation level is general;The average comprehensive score after promotion is 82.27,and the evaluation grade is good.Combined with user evaluation and field investigation,the effect of landscape improvement is tested to verify the feasibility of the design method.This paper studies the road landscape improvement design of Wuxiang Advanced Business Park from the research sequence of "theoretical summary-case reference-current situation evaluation-project practice-post improvement evaluation",which can provide reference value for the road landscape improvement design of new districts under similar development conditions.
