城镇体系结构是城市化格局及演化的基本框架。以新疆维吾尔族自治区和田地区7县1市为例,运用分形理论和引力模型分析和田地区城镇体系空间结构的时空变化特征,得出和田地区城镇空间结构由于受到地形的影响,城镇沿国道呈条状分布,城镇之间联系较紧密的结论;和田地区城镇体系空间结构以和田市为中心,城镇间的经济联系强度也以和田市最强,其周围城镇的经济联系强度随着与和田市距离的增加逐渐减弱,但随着社会、经济的发展,和田地区城镇间的联系强度在逐年增加,其中2012年1级、2级城镇的数量已达到4个,分别是和田市、和田县、墨玉县、洛浦县。
Urban system structure is the basic framework of urbanization and evolution. Taking the 7 counties and 1 city in Hetian area of Xinjiang Uygur Autonomous Region as an example, this paper analyzes the temporal and spatial variation characteristics of spatial structure of urban system in Hetian by using fractal theory and gravity model, and concludes that the urban spatial structure in Hetian area is affected by the terrain, The distribution of townships and the close relationship between cities and towns; the spatial structure of the town system in Hetian is centered on the city of Hetian, and the intensity of the economic connection among cities and towns is also the strongest in Hetian City. The economic strength of the surrounding towns and townships varies with the distance from Hetian However, with the social and economic development, the strength of the linkages between cities and towns in Hetian has been increasing year by year. Among them, the number of Grade 2 and Grade 1 towns reached 4 in 2012, namely, Hetian City, Hetian County, Jade County, Luopu County.
