摘要:

目的 通过分析陕西省特色小镇的发展模式及其空间分布特征，将有助于实现特色小镇的空间优化。方法 文章通过实地调研走访了解陕西省特色小镇的发展现状，在此基础上，系统分析该地区特色小镇的发展模式，并通过ArcGIS10.2平台，采用平均最邻近指数、地理集中指数、核密度和平均分布密度，探究境内78个特色小镇的空间分布格局。结果 （1）陕西省78个特色小镇，主要有“特色产业+”、工业主导型、“文化+”和“红色革命+”发展模式，其中“特色产业+”是数目最多的类型。（2）在空间分布类型中，特色小镇总体趋于集聚分布且均衡程度较高。（3）在市域尺度上，咸阳和渭南特色小镇分布较多，榆林、铜川和安康特色小镇分布较少。（4）在空间分布密度上，咸阳的平均分布密度最高，为11.712个/万km²，榆林平均分布密度最低，仅为1.377个/万km²。其中核密度最高的热点区域为西安东部，咸阳南部地区为次密度区。结论 陕西省特色小镇空间分布密度差异较大，通过挖掘各地发展潜力如特色产业、特色文化等，打造特色产业集群，才能积极推进全省新型城镇化的可持续发展。

Abstract:

By analyzing the development model of the characteristic towns in Shaanxi province and its spatial distribution characteristics, it will help to realize the spatial optimization of the characteristic towns. Through field research visits to understand the development status of characteristic towns in Shaanxi province, the development model of the characteristic towns in the region was systematically analyzed, and the average nearest neighbor index, geographical concentration index, and nuclear density through the ArcGIS10.2 platform were adopted. Moreover, the spatial distribution pattern of 78 characteristic towns in the territory was explored using the average distribution density. The results showed that (1) 78 characteristic towns in Shaanxi province, mainly included “characteristic industry +”, industrial-oriented, “culture +” and “red revolution +” development models, of which “characteristic industry +” was the most numerous type. (2) In the spatial distribution type, the characteristic towns tended to be concentrated and distributed with a high degree of equilibrium. (3) On the city scale, the Xianyang and Weinan characteristic towns were more distributed, and the towns of Yulin, Tongchuan, and Ankang had fewer abdomen. (4) In terms of spatial distribution density, the average distribution density of Xianyang was the highest, i.e., 11.712/10 000 km², and the average distribution density of Yulin was the lowest, i.e., 1.377/10 000 km². The hot spot with the highest nuclear density was the eastern part of Xi'an, and the southern part of Xianyang was the sub-density area. The spatial distribution density of characteristic towns in Shaanxi province is quite different. By exploring the development potential and characteristic industries of various regions, we will create characteristic industrial clusters and actively promote the development of new urbanization in the province.
