| 摘 要： | 受干旱区自然地理、人口发展与分布等特殊条件的制约,酒泉、嘉峪关地域城镇系统的空间规模结构呈现“中小市镇、多中心”的特征。针对这种状况,空间规模结构的研究和规划,应注重建构多中心的地域城镇系统,带动地域整体发展要促进相邻城市间、城市与境内或周边单位间的空间关联及与近郊集镇的融合,推动城乡一体化应突出酒泉-嘉峪关复合城市的中心地位,强化敦煌市的规模和职能,保证玉门市区持续发展并尽快发展玉门镇,积极发展其他小城镇。

| Abstract: | The article stresses two key factors: the characteristics of the physical geography and the population of arid land, with which to analyse the spatial scale structure of the city-town system in the Jiuquan-Jiayuguan region, hoping to obtain some law cognition. The study shows that in the north-west arid land of our country, the area of desert, Gobi and high mountain is vast, but the area of oasis distributes in the desert and Gobi is small. The population in the area is few, and the bearing capacity of eco-environment is limited. Under such a condition, the growth of spatial scale structure of city-town system appears such an orientational feature: "small or middle cities and towns with multipolar centres". Moreover, the north-west arid land is an undeveloped region, the spatial relation of the region is out of harmony: it's on the whole in a state of mutual nonconnection and spatial separation among those different units, cities, towns, cities and surburb's towns, due to the multiple differentiation of administration ownership and profit ownership among those different circles.The study and the plan of spatial scale structure should concentrate efforts on the development of small or middle cities and small towns, the construction of multipolar city-town system in the region, the supplement functions among the key cities or towns in each major part of the region, so as to spur jointly the regional integrated development, impel spatial connection among neighbor cities, cities and units belonging to the region or the periphery, cities and surburb's market towns, expand the population scale and the spatial scale of key city or key town in each major part of the region, push forward regional integrated development and rural-urban integration, construct a resonable, convenient, efficient regional city-town system. |
