Quality Evaluation And Optimization Of Micro Public Space In Wendong Street, Jinan Based On Vitality Measurement

In the past 30 years of urbanization in my country,behind the rapid development model is an extensive urban development model.The large-scale construction of cities has brought about rapid economic development,but the development that only pays attention to scale and not quality has brought "urban disease" to the city.The problems of urban development in old urban areas in my country are particularly prominent,with problems such as lack of space vitality,waste of space,and low quality of space.Waste,low quality of space,etc.At present,the main contradiction in our society has been transformed into the contradiction between the people’s increasing demand for a better life and unbalanced and insufficient development.The promotion of healthy cities is particularly important,and the development of cities has changed from quantitative expansion to qualitative improvement.As an important place for residents in the community to carry out their daily activities,urban micro-public spaces carry the needs of various activities such as communication,fitness,rest,and entertainment.At present,the vitality and space quality of micro-public spaces in old urban areas are quite different.This study took Wendong Street,Lixia District,Jinan City as the research scope,and collected 30 micro-public spaces through preliminary investigation,and took 19residential-type micro-public spaces as the research object.This paper uses the System for Observing Play and Recreation in Communities（SOPARC）to observe and record the characteristics,activity content and spatiotemporal distribution information of users in the micro public space,and conduct statistical analysis of the data,use SPSS software to analyze the degree of crowd mixing and behavior mixing in the space,and use Arc GIS The software Kernel Density Estimation（KDE）was used to analyze the population aggregation and distribution and visualized it.Through detailed analysis,it is finally concluded that the elements of the built environment that affect the mixing degree of space groups,the degree of crowd gathering,and the diverse types of crowd activities are mainly: leisure facilities,fitness and entertainment facilities,landscape greening,lighting facilities,space maintenance and management,space function and space interface and scale.By distributing questionnaires and conducting interviews,we learned about residents’ demands for activities and their vision for the transformation of micro-public spaces,and effectively integrated existing problems in the space,the content of residents’ activities,and residents’ willingness to transform.It has obtained the three orientations of "natural,artificial and cultural",and takes the built environment of space as the guiding factor,and proposes "optimizing ecological space and improving green landscape","optimizing spatial layout,improving artificial facilities","inheriting regional culture and promoting community civilization"."Strategies for the optimization and improvement of micro public spaces in the three major Wendong streets.Taking No.13 and No.16 micro public spaces as typical public spaces,No.13 public space is transformed into a multi-functional collection of micro public spaces,integrating rest,children’s entertainment,fitness and other functions into one.The No.16 public space will be transformed into an urban micro-garden that supports public participation,creating an ecological micro-garden integrating horticultural planting,recreation and other functions,fully demonstrating the aesthetics of urban gardens.Strive to create age-appropriate,child-friendly,ecologically green public spaces,speed up the process of urban micro-renewal,and build a livable city.
