Since 1970s large numbers of Chinese geographers have taken part in urban master planning and environmental protection, and made progress in the applied research on wind regime principle in urban master planning.But actually it has not been fully understood in urban planning and architectural circles. In order to promote the mutual understanding between architecurers, urban planners and geographers, this paper summarizes the development of wind regime principle in urban master planning of China, which is divided into four stages: 1) the principle of single prevailing-wind direction, 2) the principle of the least wind frequency and the wind direction’s rotation; 3) the principle of wind regime frequency, and 4) the principle of wind pollution index and pollution frequency. The author holds that it is better to integrate the advantages of several methods. First, to check the frequency of calm in a city, then to analyse the wind pollution index and pollution frequency of various wind directions, which is the main task of the analysis of wind regime in most of cities,finally, in urban functional zoning, to apply the typical patterns of urban layout in Fig. 1, but to change the wind direction of the least wind frequency into the wind direction of the least pollution frequency, the prevailing-wind direction into the wind direction of the most pollution frequency.
