Based on the influencing factors of surface roughness, digital terrain, and climate data, determine the city ventilation path and formulate the corresponding guidelines to promote wind circulation. At the same time, by using the numerical simulation method of GIS-CFD, simulating climate environment of the green land layout, The research first comparative analyses the difference of thermal environment with or without green space layout, and further put forward the thermal environment optimization scheme based on urban ventilation path and urban green space ventilation corridor, feedback verification by CFD, find that the urban thermal environment continued to improve. It is beneficial to put forward a practical and operable green space optimization scheme to improve the urban thermal envi- ronment from the large scale of the city and the region CFD model, and related research in this paper provide new ideas for urban green space planning and sustainable development.
