This paper compares the three urban spatial expansion features and analyzes three urban spatial expansion driving forces based on the diagrams in 2000, 2007 and 2012, Google Earth images and other basic materials of Yulin, Weinan and Hanzhong with the aid of ArcGis10.0 spatial analysis function to address the spatial evolution characters and drive forces in weak network effects regions. It demonstrates that the spatial expansion of the medium cities in three areas of Shaanxi takes on the overlap characters of economic driving and government’s adjustion and control. Especially, the pull effect of industrial projects investment and infrastructure is evident. The spatial form and expansion patterns have no direct relationship with the distance to regional central city. |
