Research Of Improvement Strategy On Pingshan Village Street Space Based On Multi-agent Objective Collaborative Optimization

Traditional villages are the product of farming civilization,and contain multiple values such as society,history,economy,culture,and tourism.Street space is its skeleton and blood,the core of the village 's overall composition and public activities.As well as the rapid advancement of the tourism industry,traditional villages,including their streets and spaces,are facing problems such as lack of culture,alienation of style,weakening of places,and environmental damage.Based on the above background,this paper takes the street space and the main body behavior of Pingshan Village in Yi County as the research object,combines field investigation,spatial syntax analysis,behavior observation and other investigation and analysis methods to discuss the street space of Pingshan Village from multiple angles The basic space composition characteristics,the internal information order of the place and the cognitive evaluation of different subjects aim to discover the main problems in the protection and development of the street space,and propose corresponding optimization and improvement strategies.Firstly,this article makes a detailed and basic investigation and analysis of the street space from the aspects of the generation environment,space form and structure,material constituent elements,proportion and scale of the street space.Furthermore,in order to further understand the internal structure logic and space characteristics of the street space,based on the spatial syntax theory,two methods of axis analysis and horizon analysis are used to integrate the street space,the degree of integration,the degree of understanding,the degree of control,and The indicators such as visual field integration degree,visual field control value,visual field occlusion degree and simulation analysis of crowds were analyzed.At the same time,from the perspective of the subject's behavioral cognition,the three main user groups(villagers,students,tourists)in Pingshan Village were observed and summarized and analyzed their activity laws,and on this basis,the space and The consistency and difference of the relationship between behaviors.Finally,taking the issue as the guide,specific improvement strategies are proposed for the problems of the lack of spatial appearance of the streets,the polarization of spatial vitality,the lack of infrastructure,the deterioration of the landscape environment,and the lack of cultural features.At the level of street and street space protection and update,measures such as controlling street and street style,continuing street and street interface,improving environmental facilities,and reshaping humanistic style are proposed;at the level of improving street space and improving coordination of multi-agent needs,it is proposed to expand street and street nodes,Standardize format management,integrate street and lane systems,and improve street and lane recognition.This study provides a useful reference for the protection and inheritance of traditional villages.
