Study of Central Cities Service Scope Based on Time Accessibility in Gansu Province

Abstract:

With support of GIS software, we use the spatial analysis method of vector data. Calculating the isochronous rings of central cities, and prefecture-level cities’ time accessibility. Then we divide city service scope. Next we using ArcInfo programming in linear programming optimization technology to optimize the city service scope. The results show that, the magnitude has changed dramatically among city service scope after optimization, before optimization, and the city administrative divisions. It provide technical and theoretical support for government departments to make planning of city zone divides.
