Microclimate Analysis And Thermal Comfort Evaluation Of Park Green Space In Summer

At present,with the rapid development of urbanization in the Yangtze river delta region,more and more attention has been paid to the urban ecological problems.The urban microclimate has seriously affected people's normal life and health during the hot weather in summer.As one of the most important types of urban outdoor space,park green space not only beautifies' the urban landscape but also improves the urban microclimate.It is of great significance to study the summer microclimate effect of park green space for guiding the planning,construction and management of park green space and improving the quality of urban outdoor environment.However,China's climate types are complex and diverse,so it is urgent to study the microclimate in Suzhou by field measurement.Taking the park green space of Suzhou Jinji Lake central business district as the research object,this study respectively used the methods of literature research,site measurement and mathematical statistics.Firstly,theoretical studies on related urban microclimate and park green space are reviewed,including the influence of park green space and plant community on urban microclimate and the evaluation of park green space microclimate based on thermal comfort.Secondly,based on the results of remote sensing data inversion analysis,eight park green spaces in the central business district of Jinji Lake in Suzhou city were selected as the measured sample plots.On the basis of the preliminary investigation,our team measured the microclimate factors of the park green space on the hot days in summer,and discussed the influence of the park green space and plant community on the microclimate of the park green space from two aspects.Finally,combined with the mutual verification of user subjective questionnaire survey results and thermal comfort evaluation indexes of park green space,this paper conducted an evaluation study on thermal comfort of park green space in Jinji Lake central business district of Suzhou in summer.This paper lays a foundation for the analysis and evaluation of the summer microclimate environment in Suzhou,and provides data support and practical measurement conclusions.On the one hand,the research conclusion provides reasonable suggestions for optimizing the planning,construction and later management of park green space;on the other hand,it provides reference basis for people's outdoor travel from the perspective of park users.
