划分城镇经济区对于进行城乡产业和公共服务设施布局、统筹城乡协调发展具有重要意义。通过构建评价指标体系,运用主成分分析与重力模型法,计算城镇发展潜力,在此基础上选择了14个中心镇,并求得其与中心城市、特区及城关镇的中心性强度。根据断裂点理论,运用加权Voronoi必威现金回扣,以城镇中心性强度值的平方根为权重划分各中心城镇的空间影响范围。在保持乡镇行政区完整性的前提下,对城镇影响范围进行调整,最终确定了十堰市22个城镇经济区的覆盖范围。结果表明,城镇影响范围还取决于中心城镇间的距离,城镇经济区范围通常与行政范围不一致。在今后的研究中还需考虑自然资源、周边城市影响等因素,不断完善研究方法。 更多还原

【Abstract】 To divide town economic zones is important to allocate the urban-rural industries and public services facilities,as well as to improve urban-rural coordinated development.By establishing the development potential index system of towns and using Principal Component Analysis and Gravity Model,14 center-towns were selected,meanwhile,all the central cities and towns′ impacts on surrounding areas were calculated.Based on the Breaking Point Theory,the spatial impact scope of each central town was gene...
