成都市是我国西南地区重要的中心城市之一。在统筹城乡的背景下，区域发展模式发生调整，城镇体系地域空间结构的合理发展是实现城乡统筹发展的重要保证。因此，定量的分析成都市城镇体系空间结构特征，有助于寻求区域内集约发展最合理的模式以及为制定统筹城乡发展战略提供决策支持。本文在 GIS空间分析功能的支持下采用成本加权距离改进空间相互作用理论模型---场强模型，对成都区(市)县城镇与城镇之间、城镇与区域之间的相互作用进行了定量分析。研究结果直观地反映出各城镇强影响区在市区附近呈团状紧凑、在外围呈点状分散的空间特征，成都市区对其临近的周边行政区的影响显著，但是在西部的区县触及范围相对较小。

Chengdu is a great metropolis of the Southwest China.In the context of urban-rural harmonious development,the regional development mode is adj usting.The reasonable development of spatial structure of the town system is an important guarantee for urban and rural development.Thus,the quantitative a-nalysis of the spatial structure of town system in Chengdu City is beneficial.It helps to seek the most rea-sonable mode of intensive development in the region,and provide decision-making support for the urban-rural harmonious development strategy.Based on the theoretical model of spatial interaction-the field po-tential model which has been improved by the cost weighted distance.This article has calculated the field-strength of each grid of the study area influenced by towns with the support of ArcGIS software.Subse-quently,we have analyzed the interaction between the towns in the study area.The results reveal that the strongly affected zones are in a cluster near the metropolis of Chengdu,and punctuate dispersed in the out-skirts.The metropolis of Chengdu significantly affects its nearby surrounding areas,but relatively small influence in the western counties.
