Abstract  

Understanding the link between greenspace patterns and land surface temperature is very important for mitigating the impact of urbanization on Urban Heat Island (UHI) and also useful for professionals and decision\|makers during the design phase of urban planning.Previous most researches were conducted to examine the cooling effects of greenspace amount,composition and configuration (spatial arrangement).Few have examined the cooling effects of spatial layout of greenspace (referring to space combination form of greenspace).Five scenarios of greenspace patterns are selected to examine them how to affect the horizontal and vertical distribution of the temperature coupling remote sensing data with a Computational Fluid Dynamics (CFD) model(ENVI\|met model).The simulation results demonstrate that zonal pattern always has the best cooling effect;dotted pattern has the best cooling effect on local ambient temperature.The temperature distributions have many similarities between radial and wedge patterns,which can become the “cold source” of urban thermal environment and play an important role in the improvement of the urban ecological environment.
