摘要
采用定量分析的办法,构建了青海省城镇城市化综合水平指标。利用该指标和城镇空间相互作用的理论,得到青海省各城镇之间的相对空间相互作用引力指数(Wij)。结果表明:Wij>0.4时,两城镇之间存在较强的相互作用。此类城镇主要集中在青海省东部,以西宁为核心,湟中、平安、大通、湟源、乐都、互助为次级中心,化隆、循化、门源、海晏、尖扎、共和、贵德为三级城镇形成城市圈;Wij非常小的区域,主要集中在柴达木盆地和青海高原地区,未来空间布局为点核式资源中心发展城市和生态型Ⅱ级县域中心城镇。
The urbanization comprehensive level index of Qinghai province towns is established using a quantitative analysis method in this paper and the roomage interacting gravitation index （Wij） between the towns in Qinghai province have been obtained too by the application of the index and the theory of town roomage interaction. The result shows that there is a stronger interaction between two towns if Wij〉 0. 4 and this kind of towns are mainly in the eastern area of Qinghai province. Xining city is the center,Huangzhong,Pingan,Datong,Huangyuan,Ledu and Huzhu are the subcenters and Hualong,Xunhua,Menyuan,Haiyan,Jianzha,Gonghe and Guide are the third grade town zone. The regions with a very small Wij are lovcaed in Caidamu Basin and Qinghai plateau area and the future roomage layout will be the point - core type of resources,central development city and ecologic Ⅱ grade county region town.
