The Features And Simulations Of The Two Kinds Of Green Space Layout On Microclimate

With the sustainable development put forward, the Copenhagen conferenceconvene, the use of eco-design, all of that have shown us the human desire of theoriginal natural environment. Urban climate as a large regional climate context of theformation of relatively independent micro-climate, with urban development andhuman activities are closely related. Urban green space is the most closely of greenpublic space that related to the daily life of urban residents, it can not only provide thevenue for the residents’ leisure activities, but also for the improvement of the urbanmicro-climate environment and increase the comfort of the people’s livingenvironment plays a role can’t be underestimated. Under different climatic conditions,in-depth study of the relationship between urban green space form and urbanmicro-climate and response mechanism, improve the urban microclimate, provide animportant means of livable ecological environment, but also in recent years, manycities, landscape and ecological studies scholars focus of attention.In this paper, the theory of the urban climate as the support, Henan AgriculturalUniversity, the third living area as the research object, through field investigation andobservation, analysis comparing different green layout of wind, temperature, humidityand other environmental factors of microclimate differences between building anumerical model explore the response mechanism between the different green layoutand urban micro-climate for the planners to provide a new method to improve theurban local micro-climate. The research results show that the central green spacecooling effect is better than distributed green, the former average temperature to belower than1.2℃, and the former green space ventilation effect, the average windspeed is higher than the latter0.3m/s. Overview of experimental site, build anumerical model based on Envi-Met compared verify the model shows that the central green space temperature is below dispersed green space of1.5℃, the wind speed ishigher than the distributed green space of0.5m/s. The gap between experimental dataand simulation data, basically the same, studies have shown that the Envi-met modelto some extent, and can basically reflect the Current Situation of the actualenvironment and climate research site, a city-scale micro-climate studies provide anew approach.
