A comparison on urbanization of two mega polises in western China in recent 20 yearsversity,

Based on a comparison of the spatial extension modulus and speed of the two megapolis cities in western China, Chongqing and Chengdu, the differences of urbanization characteristics of the two cities were analyzed. The results show that the two cities have different spatial extension modulus and extension speed. The extension speed of Chongqing, the largest mountainous city of China, was slow and its extension direction was along the Yangtze River valley and the Jialing River valley. Chengdu, the largest plain city of western China, had a faster extension speed than Chongqing and a concentric circles extent modulus. The spatial extent modulus and speed were controlled by the natural condition, especially the topography, the policies, the economic development level and the investment of the state central government.
