Abstract: Ventilation is an important measure of urban low-carbon ecological construction. This research is based on the domestic and abroad research of urban planning and Climatology. Using simulation technology to analyze the ventilation on regional scale, identifying the potential areas of ventilation and construction recommendation, the research shows that: 1) The simulation of WRF meso-scale forecast model system has a good analysis effect, which can reflect the characteristics of wind environment in the Pearl River Delta; 2) Analyzing the ventilation potential of different types of underlying surface, the research identifies the North River of Foshan, the Liuxihe River of Conghua, the areas of Yangcun and Botang in northern Huizhou, Baipenzhu Reservoir of Huizhou as the winter wind inlet, while the Lingding Bay, the coastal area of Doumen in Zhuhai and the Daya Bay area in Huizhou as the summer wind inlet; 3) The research also identifies that the downwind areas of the towns, villages, rivers and mountains in the Pearl River Delta can be taken as the regional ventilation potential area; 4) With regional united prevention, comprehensive utilization of space and integrated design, the research raises some suggestions about implementation of ventilation corridor construction.

Key words: regional wind environment, ventilation, WRF, imitation, the Pearl River Delta
