以青海省4个城市作为研究对象并建立评价系统,用熵值法和城市首位度方法,对城市的中心性、规模分布和区域差异进行了定量分析。研究表明:西宁市作为其中心城市,在各方面是中心性最强,且首位度分布明显。西宁市的城市中心性极为显著,且与其他四城市之间的差距甚大。海东、格尔木、德令哈三城市发展水平低且差距较小。相对来说,四城市在交通中心性差距最小,在科教中心性上差距最大。
In this paper, four cities in Qinghai Province were selected as research objects and an evaluation system was established. The entropy method and the first degree method were used to quantitatively analyze the centrality, size distribution and regional differences of cities. The research shows that Xining as its central city is the most central in all aspects, and the distribution of the first degree is obvious. Xining city center is extremely significant, and the gap between the other four cities is very large. Haidong, Golmud, Delingha three cities with low level of development and the gap is small. Relatively speaking, the four cities in the transport center of the smallest differences in science and education between the center of the largest gap.
