Study On Microclimate Response Of Urban Green Space In Handan City Comprehensive Park

With the development of building an ecologically livable city,the study on the suitability of microclimate in urban park green space has received extensive attention.In this study,three city parks in Handan City were selected as research objects to explore the influence between the components of green space and the microclimate,and provide strategic suggestions for the future construction of green space in the region.Based on the existing research,this paper discusses the impacts on the microclimate factors affecting green space and has certain supplementary effect for the research of related green space microclimate.In this study,field data were collected in summer and winter,and the plots were set according to different factors such as park green space structure and the underlying surface,different medium and small climate data were tested.According to different microclimate change data,the response mechanism of urban green space microclimate change factors was analyzed,a multi-factor regression model was established,and the correlation between human comfort and microclimate impact factors was studied.The results are as follows:(1)The characteristics of microclimate change around the water body of the park and the comfortable analysis of human comfort.There are differences in temperature and humidity effects at different distances around the water body.The summer temperature and humidification effect are the best at the edge of the water body,and the large water body has a wider range of influence on the surrounding microclimate.Temperature and wind speed have significant effects on human comfort index,and predictive models are made by multi-factor linear regression.(2)Exploring the microclimate differences of different vegetation structures in green space.Significant differences between different vegetation structures were analyzed by one-way ANOVA and multiple differences.(3)Exploring the difference in temperature and humidity effects of green space in different comprehensive parks in Handan City.(4)Research on the correlation between user behavior and microclimate comfort.The study found that users will choose a small climate and comfortable place to carry out activities according to their needs.(6)Exploring the difference between human comfort index DI and actual human thermal sensation,thermal comfort,the results show that there is a certain deviation between the two.Aiming at the characteristics and impact mechanism of microclimate changein urban park green space,this study also discusses the design strategy of the urban comprehensive park in the City and provides a theoretical basis for the planning and construction of urban green space system.
