According to the analysis of ring roads in 16 cities, this paper presents a principle of ring road spacing between cities in China: The city ring roads in China accord with golden section number (ω = 0.618033988...) or golden section number reciprocal (1/ ω = 1.618033988...) from the outside to ratio of the inner spacing. According to ring road spacing ratio China's ring roads can be divided into three ring types of A, B, C: A type standard ratio is 1/ω; B type standard ratio is ω; and C type is 1/ω in the upper standard of longitudinal direction (from south to north) ratio and ω in the upper standard of transverse direction (from east to west) ratio. Case analysis indicates that China's city ring roads spacing ratio accords basically with this principle. The principle applies to the city ring roads of different scales, characteristics and different forms. Applying this principle, it is possible to carry out planning and raise suggestions for China's city ring roads as well as their rationality appraisals.
