湿热地区街头绿地微气候效应数值模拟分析
Analysis of the effect of street greenbelt on microclimate in a hot-humid area of China using a numerical simulation method
摘要
Abstract
The microclimatic conditions surrounding street greenbelt in a business zone of Shenzhen were simulated using an urban microclimate soft-ENVI (ENvironment for Visualizing Image)-met.The accuracy of simulating re-sults was validated using the field measured data.It shows that the ENVI-met model can accurately describe the characteristics of microclimate spatial distribution and diurnal variation in the study area.The microclimate effects of three landscape types,i.e.tree,lawn,and waterscape,are compared using the ENVI-met model.By comparing air temperature and humidity,it indicates that the cooling and humidification effects are different among these street types.The tree greenbelt is the best,followed by lawn,and waterscape.However,the characteristics of daily varia-tion and spatial distribution of cooling and humidification effects for them are consistent.Compared with land sur-face temperature,it demonstrates that there is a heating effect in the tree and lawn street greenbelts on the adjacent pavement.In contrast,the waterscape street greenbelt plays a cooling effect on the surface of surrounding pave-ments.These results provide valuable information for designing climatic adaptability plans on the urban street greenbelt.关键词
