Research On Optimization Strategy Of Yulin Urban Spatial Form Based On Landscape Ecological Factors Perception

With the advancement of urbanization,the construction of cities is getting faster and faster.High-rise buildings have sprung up.In the development of the city,the natural elements of the original city,such as mountains,water systems,and terrain,are covered by some artificial buildings,and people are in the city.The perception of landscape ecological elements is weakened.Especially in the current vigorous promotion of ecological civilization in the country,President Xi also clearly stated in the report of the 19 th National Congress that it is necessary to establish and practice the concept of green mountains and green mountains.The protection and construction of the city's natural environment is also the new economic normal.Important issues in ecological construction.How to carry out good interaction and coordination between urban natural landscape ecological elements and urban built-up areas is also an urgent problem to be solved.This paper begins with the analysis of the relationship between landscape ecological element perception and urban spatial form.Kevin Lynch's urban imagery theory is used to analyze the relationship between perception and urban spatial form.The subject and object of perception are explained,and the perception of urban imagery is based on the people(residents and tourists)in the city,and the landscape ecological elements(mountain,water system and natural features)in the surrounding environment of the city are taken as The object of urban spatial image perception should be able to be perceived,and then by analyzing the influence of landscape ecological elements on urban spatial form,the relationship between landscape ecological element perception and urban spatial form is obtained.Secondly,it analyzes the relationship between the evolution of the spatial form of Yulin city and the perception of landscape ecological elements,and uses GIS technology to simulate the process of perception of landscape ecological elements in the evolution of Yulin city.From the three aspects of the spatial perception feature of Yulin city,the open area of landscape ecological perception and the perceptual view,the paper reveals the influence of the spatial shape of Yulin city on the perception of landscape ecological elements,and finds out the combination of analysis.The spatial form of Yulin City is based on the problems existing in the perception of landscape ecological elements.Thirdly,this thesis constructs the optimization method of Yulin urban spatial form in the real problem of urban spatial form under the premise of landscape ecological elements in Yulin City.From the perspective of planning,it cuts into macro,meso and micro perspectives and constructs three Hierarchical spatial shape optimization method.Finally,based on the optimized method of construction,the specific strategy for optimizing the spatial shape of Yulin city is proposed.Through the research of this paper,we try to explore the way of urban spatial form based on the perception of landscape ecological elements.It is to propose specific strategies for optimizing the spatial form of Yulin city,and it can also inspire other urban spatial form construction.
