【摘要】：本研究以石羊河流域为研究区,选取2000、2006、2010年三期遥感影像为数据源,采用成本加权距离和城乡聚落体系潜能指数对传统的场强模型进行改进,综合利用扩张强度指数、扩张速度指数等分析研究石羊河流域内部城乡聚落体系空间结构分异。在此基础上,基于GIS技术并结合道路等级和长度计算流域内城乡聚落体系间最短时间距离来分析城乡聚落体系空间联系与空间相互作用,据此分析石羊河流域城乡聚落体系空间结构变化及影响模式。
[Abstract]:In this study, Shiyang River Basin was used as the study area, three issues of remote sensing images in 2006 and 2010 were selected as data sources, the traditional field strength model was improved by cost-weighted distance and potential index of urban and rural settlements system, and the expansion intensity index was comprehensively utilized. The spatial structure differentiation of urban and rural settlement system in Shiyang River Basin was studied by means of expansion velocity index. On this basis, the spatial relationship and spatial interaction between urban and rural settlements system are analyzed based on GIS technology and the shortest time distance between urban and rural settlements system. The spatial structure of urban and rural settlement system in Shiyang River Basin and its influence model are analyzed.
