Landscape Design Of Basin City Park Based On Microclimate Regulation

As a good health carrier,urban park is a public space with high frequency of use in People’s Daily life.It plays an important role in adjusting spatial microclimate environment and improving outdoor thermal environment.Give full play to the positive role of landscape elements,adjust the spatial microclimate environment,It can effectively alleviate the deterioration of urban outdoor environment and form a suitable comfortable environment for human body.Based on the relevant research foundation at home and abroad,Taking Yueping Park,Pinghu Park and Xihu Park in Hengyang City as the main research objects,the summer with the most obvious microclimate effect was selected.By analyzing the behaviors of the users of the sites,42 landscape spaces with high utilization rate and obvious spatial structure characteristics were selected as microclimate data measuring points,which were conducted for 3 days from 6:00 am to 19:00pm,to explore the influence of various landscape elements of urban parks on microclimate,to study the microclimate regulation effect of different types of urban parks,to analyze the influence of different underlying surface composition and paving materials on microclimate,and to analyze the influence of different types of basic unit spaces The human body comfort index(SSD)was selected as the evaluation index to study the influence of different landscape elements on the microclimate environment and human thermal comfort,and analyze the correlation between the human body comfort index and microclimate factors.According to the microclimate temperature and humidity characteristics of each landscape space,The landscape design strategy of basin city parks based on microclimate regulation is put forward,and different types of landscape spaces are selected to optimize the landscape design of city parks,so as to provide some reference and supplement for the landscape planning and design of the same type of city parks,and promote the design optimization and organic renewal of city parks.The results show that in the hot summer of the basin city park,there are obvious differences in the microclimate adjustment ability of each landscape space of the three different types of city parks,Pinghu Park >Yueping Park > West Lake Park;The average daily temperature of the six types of underlying surface from high to low can be sorted as: hard pavement > water > grassland > soil > structure > forest land,and the average daily temperature of each pavement material from high to low is: granite >plastic > asphalt > fired brick > concrete > anti-corrosion wood > lawn;In the basic space units of different types of landscape,the human comfort index of space from high to low is: square space > plant space > water space.The temperature of the square space is high,the warming effect is obvious,the richness of the plant community in the landscape space and the effective shading area affect the temperature and humidity of the space,and the water space has a high ability to regulate humidity and maintain stability.The spatial structure,the composition of the underlying surface,the degree of space shade,geographical location and other factors will affect the temperature and humidity effect in the landscape space;the human comfort index of the park environment is significantly correlated with climate factors such as temperature,relative humidity and demeanor;the structural characteristics of the landscape space,the effective shade area,the surrounding environment and pavement materials will affect the comfort of the space;To improve the comfort of landscape space in urban parks,the microclimate environment of landscape space can be adjusted by combining the plane pattern of urban parks,reasonably selecting the composition and combination of different landscape elements,properly increasing the shade and canopy density of vegetation communities,and reducing the proportion of hard pavement in the overall pavement material.
