国家城市等级体系的世界格局
World pattern of national urban hierarchy system
摘要
Abstract
In order to overcome the simplicity of the primacy index and the incommensurability of the rank‐size model , this paper selects unbalanced index of the urban hierarchy system (S) , the population of the largestcity(P)andurbanprimacyratio(R)tostudytheworldpatternofnationalurbanhierarchysystem . On this basis , firstly the 156 national city population is divided into 10~25 million , 25~50 million , 50~100 million ,100 ~ 500 million , more than 500 million of 5 grade , calculating unbalanced index of the urban hierarchy system (S) and city primacy ratio (R) , removing 31 countries of S= 1 , at last using hierarchical cluster and SOFM to reveal the world pattern of national urban hierarchy system . The result shos , that the world pattern of national urban hierarchy system can be divided into 6 types :the higher‐medium grade balance , the medium grade balance , the primary grade balance , the primary‐medium grade unbalance , the primary grade unbalance and the primary primacy . Classification results show that the classification effect is good , and it can reflect the similarities and differences between the nations using .关键词
