Research On The Defects Of Public Space Design Under The Background Of Smart City ——Taking Nanhu District Of Jiaxing As An Example

Urban public space once put forward the "third space" from the perspective of urban and social research.Public space is the external space on which human beings live and engage in activities.It emphasizes not only the openness of space but also the open connection with the diversity of activities,which not only defines the urban structure but also demonstrates the vitality of the city.With the rapid development of the city,the public space has gradually become morbid.At present,Nanhu District of Jiaxing,as a central city connecting Shanghai and Hangzhou,is in the period of smart city development,but it faces many challenges.For example,the desolate scene of commercial square,the interaction of people in residential street,the quality of public space in industrial park is not high,the quality difference between public space and lack of certain later protection and management,resulting in the lack of vitality of some space,residents’ mental health and other problems.During the "13th Five-Year Plan" period,Nanhu District takes scientific and technological innovation,green ecology,livable business and shared development as the core innovation and development,and gathers strength to fight the "four major battles".In addition,future-based and smart city construction will help improve the vitality of urban public space and the quality of life.Under the background of smart city in Nanhu District,this paper takes the public space of Nanhu District in Jiaxing as the main research object,and selects the main activity and work place of urban residents--industrial park.The main entertainment area--business district;The main living area--residential area.Space in the form of three different activities in the road,guide system,public facilities,landscape nodes,green space system in various public space elements,based on the intelligent city background,through the qualitative method,field investigation method,observation method,questionnaire survey method,logic reasoning method,method of three kinds of public space in the five factors to promote study.Firstly,the public space of commercial district,residential district and industrial park is analyzed and studied,and residents’ psychological factors are considered and residents’ participation is made to become the medium of physical space connection and interactive connection as the measurement standard of the overall study,so as to improve residents’ interactive satisfaction.Secondly,under the guidance of five principles of comfort,aesthetics,history,policy and economy,it makes an in-depth analysis to find the existing shortcomings of space from large to small.Then from the small to see the big,from the micro point of view to find out the solution,increase the spatial communication,spatial greening diversity,spatial physical connectivity,while emphasizing the interaction between man,machine and environment.Finally,a reasonable "smart Nanhu" public space design system is obtained from the above research,and all elements in nanhu Industrial park,commercial district and residential district are reformed and upgraded.Based on the background of smart city in Nanhu District,this paper studies the practical application transformation and improvement of public space in industrial parks,residential areas and commercial areas in Nanhu District.Using a variety of research methods,this paper puts forward reasonable suggestions and systems for the intelligent design and development of public space in Nanhu District.It provides reference for future urban public space design.
