The result s show t hat t here are o bvio us difference amo ng 15 cities in urban hinterland areas, mo reover, t he coincidence degree between urban hinterland areas and t heir administrative region is lower. According to t he result s and conclusions, Gansu Province can be divided into 5 first2class urban economic regions. On t he basis of division for urban hinterland, some suggestions on fixing the region spatial struct ure of town system in Gansu Province are p ut forward. Key words : urban hinterland ; urban eco no mic regio n ; GIS ; Gansu Province ; urban system. [ 1 ].,,.,, 2,,,,, : 2006Ο12Ο20 ; : 2007Ο03Ο06 : (40671061) ; : (1974 ),,,,. GIS.
