Study On The Correlation Between Typical Microclimate Factors And User Behaviors Of Summer Urban Squares In Hefei

With global warming,the climate conditions are becoming more and more severe,which affects the comfort of people's leisure life,especially in areas with hot summer and cold winter.Hefei is a typical city with hot summer and cold winter.Extreme high temperature in summer is one of the key reasons for the low utilization rate of urban public space.At the same time,the planning and design of most urban public spaces pay too much attention to form and spatial relationship,which is more comfortable for users.The climatic environment of these places is difficult to meet people's increasingly high requirements for the climatic environment under severe climatic conditions.Urban square is an important part of urban public space,so it is very important to study the correlation between urban square users and micro-climate environment and explore users' needs for micro-climate environment.Based on this,this paper,taking the central square of Hefei government affairs as an example,combined with environmental behavior and microclimate research methods,analyzes the correlation between the microclimate environment and user behavior of the central square of Hefei government affairs,and then provides strategies for the planning and design of urban squares in regions with hot summer and cold winter.This paper takes Hefei Municipal Government Central Square as the research object,and uses qualitative and practical measurement methods to explore the correlation between site users' behavior and microclimate environment in summer.Firstly,methods such as field observation and measurement were used to collect relevant data such as user behavior and microclimate.Then,tools such as Excel and Arc GIS were used to analyze the data of microclimate and user behavior respectively,so as to obtain the microclimate situation,user attendance and space-time distribution rules of each measurement point.Then,En VI-MET numerical simulation tool was used to simulate the microclimate environment of the whole square.SPSS statistical method was used to analyze and study the correlation between the microclimate environment of the square and user behavior.Found that summer city square in the hot summer and cold winter region,energy metabolic equivalent less leisure entertainment activity and the strongest correlation of micro climate,metabolic equivalent maximum exercise class activity and correlation of the micro climate the weakest,and different activity behavior and micro climate factor correlation degree are different,generally,the temperature effect on user activity is the largest.According to the correlation analysis,the article USES the grid analysis,compare the different space micro climate environment and user space distribution characteristics,puts forward corresponding space micro climate to improve concrete Suggestions,and from the space planning and functional layout,the optimization of micro climate,activities motivation from three aspects for improving urban square summer hot summer and cold winter area utilization rate,The general optimization strategy is proposed to meet the needs of users for different activity comfort.
