Evaluation And Optimization Of Thermal Comfort Of Slow Walking Trail In Shijingshan District Of Beijing

With the continuous development of the country and the gradual improvement of people’s living standards,at present,cities have put forward higher requirements for the construction of urban slow walking trails.As the most commonly used pedestrian path in people’s daily life,urban slow walking has become an indispensable element in residents’ lives.Improving its microclimate environment is of great significance to enhance people’s sense of happiness,enhance their willingness to travel,and improve their walking comfort.This article is based on the research status of slow walking trails both domestically and internationally,as well as the analysis and organization of slow walking trail theory and microclimate theory.Taking the slow walking trail in Shijingshan District as an example,a GIS network system is used to construct a slow walking trail network system in Shijingshan District.According to the nature of the road,the slow walking trail in Shijingshan District is divided into six categories:urban roads,industrial parks,commercial industrial parks,waterfront parks,roadside green spaces,and specialized parks.Twenty roads were selected for preliminary analysis based on the distribution characteristics of usage time,pedestrian flow on the trail,and actual research results.Subsequently,six typical trails and 18 measurement points were selected based on the analysis of the current situation of the slow road network,slow traffic landscape,and slow traffic facilities.Microclimate data was collected from the selected 18 measurement points using big data and a microclimate database was established for the typical trails.Data analysis was conducted on the selected measurement points from four aspects: air temperature,relative humidity,wind speed,and solar radiation,Summarize the microclimate characteristics of different spatial types of trails.Using Envi met simulation software,simulate and analyze the six typical trails selected,and select the simulated data at 12:00 noon for microclimate and comfort analysis.Based on the analysis of microclimate data,this article selects Yongding River Forest Park for landscape optimization simulation verification.Based on the simulation data results of microclimate and comfort,optimization design strategies are proposed to provide theoretical support and practical basis for future related research.
