| In recent years,global climate change has become increasingly fierce,breaking the previous climate change laws and even affecting people’s production activities.Scholars from all over the world have begun to pay attention to the solutions to major climate problems,but the focus of current research is mainly on urban areas with large scale and rapid economic development,and there is little research on economically underdeveloped rural areas.Traditional villages,as the crystallization of people’s life and work,observation and adaptation to the surrounding environment for thousands of years,have a special position in rural areas.Its outdoor space is an important place for villagers and tourists to live and relax,and it is of great significance to study its thermal comfort for people’s physical and mental health.Taking Shimengao Village,Tangxi Town,Guichi District,Chizhou City as the research object,this paper identifies the core area of traditional village integration based on spatial syntax theory,explores the distribution of microclimate and thermal comfort in the core area of traditional village integration,as well as the interaction between different climatic factors and the influence mechanism on thermal comfort,seeks the planning and microclimate transformation and upgrading methods suitable for traditional villages in southern Anhui Province,and studies the humanized design of outdoor space in traditional villages from the perspective of improving thermal comfort of outdoor space.Firstly,the research progress of rural microclimate and human thermal comfort at home and abroad is summarized,and the technical route of this research is put forward.Secondly,the outdoor space form,building size,plant species and underlying surface types of Shimen Gaogu Village in Chizhou City were investigated and recorded.The Depthmap software is used to identify the area(the core of integration)with the highest frequency used by villagers and tourists in traditional villages as the research area.Then,the determination coefficient(R)is introduced as an index to verify the suitability of ENVI-met for traditional village simulation research.Thirdly,the air temperature,wind speed,radiation temperature and physiological equivalent temperature(PET)of two typical days in Xia Dong are selected as evaluation indexes.ENVI-met software is used to simulate the distribution of microclimate and thermal comfort in the core area of traditional village integration in two typical days in Xia Dong,and the evaluation indexes are analyzed,and the internal influence laws of microclimate and thermal comfort are summarized.Finally,three typical types of space in the core area of traditional village integration are summarized: square space,street space and courtyard space,and the detailed models and underlying surfaces of the three outdoor spaces are constructed.ENVI-met software is used to simulate on typical days,and the temporal and spatial distribution laws of thermal comfort of the three different types of outdoor spaces in winter and summer are analyzed.Based on the analysis results,the optimal design strategy of outdoor space is summarized.The space with bad thermal comfort environment in summer is optimized and modeled by using specific improvement and upgrading strategies,and the space-time ratio of thermal comfort before and after transformation is compared and analyzed,which verifies the feasibility of the strategy and provides a new idea for the planning and design of outdoor space in traditional villages.The main conclusions of this study are as follows:(1)Using spatial syntax theory to extract the integration core of Shimen high traditional village and analyze its microclimate measured data.(2)Summarize the development status of ENVI-met numerical simulation software and verify its suitability for traditional village simulation.(3)Select relevant indicators to analyze the microclimate and thermal comfort in the core area of traditional village integration in Xia Dong in two seasons,and reveal the interaction mechanism between different factors.(4)The temporal and spatial distribution of thermal comfort of three different types of outdoor spaces with the characteristics of traditional villages in Xia Dong in two seasons was comparatively analyzed.(5)Propose the optimization strategy of outdoor space in traditional villages based on improving thermal comfort,and carry out experimental design for the space with poor thermal comfort in traditional villages in summer,verify the feasibility of the strategy.The research results enrich the examples of thermal comfort research in the field of traditional villages,and can provide reference for traditional village planning and design,environmental improvement and so on.Figure [35] Table [18] Reference [76]... |
