新疆丝绸之路沿线城市空间关联性测度

Evaluation on spatial association between cities along the Silk Road

以城市群理论及空间分析方法分析了新疆"丝绸之路"沿线城市带的空间关联特征及规律。结果显示:新疆"丝绸之路"沿线城市群属于"一极双核"和"分散组团"空间关联模式,中心职能及空间关联性不强;乌鲁木齐市的首位性突出,但其关联范围主要是乌—昌经济圈;关联职能局限于外向性或国际化,内联性不足弱化了城市群的辐射带动功能,加剧了过度城市化问题;二级中心城市与首位城市间的发展断层巨大,彼此间的空间关联不足,团聚规模小、层次低、功能弱,趋同、内聚、稳定等地方性职能突出;城市发展缺少外向活力和升级动力;石(河子)—玛(纳斯)—沙(湾)组团较克(拉玛依)—奎(屯)—乌(苏)组团关联适度。

Using urban agglomeration theory and spatial analysis methods, this essay studies and analyzes spatial correla- tion characteristics and rules of the cities along the Silk Road in Xinjiang. Spatial association model of the urban agglomeration is ＂One pole Dual - core＂ and ＂dispersion group＂ , which central functions and spatial association are not strong. As Urumqi is the first - level central city, its status is prominent. But its spa- tial association scope includes mainly Urumqi - Changji Economic Circle. So is its hinterland. And its associated function is lim- ited to extraversion and internationalization. That the lack of its association scope is weakening function of radiation of the city is contributing to excessive urbanization. Compared with the first - level central cities, second- level central cities have a great fauh, lack of spatial association between the levels of the cities and with each other, with small scale, low level, the weak func- tion in the reunion of the city, with local functions such as con- vergence, cohesion and stability, and lack of outward energy and upgrade momentum to the development of the city. Among them, the spatial correlation of Shihezi - Manasi - Shawan towns group is more modest than of Karamay - Kuitun - Wusu towns group. Lower central cities are also fractal and initial prototypes.
