| Abstract: | In the article, by using several methods, we have analyzed the grades of urban centers and spatial connection of urban areas in Gansu Province. We pointed out that the degree of premier city is high in the structure of Gansu urban grade and scale, there is no such a city whose population scale is between 500 000 and 1000 000 and the spatial connection between different central cities is quite different. Furthermore, we find that urban areas in Gansu exhibit a typical linear distribution, a strong transportation direction and are mainly distributed along the development axes which include the Longhai-Lanxin Railway and National Highway No. 312 and No.109. In the end of the article, we offer some suggestions for future development of urban areas in Gansu Province. |
