摘要： 分析了主城对卫星城市经济扩散作用与热传导现象的相似性，引入了经济扩散通量的概念．参照热传导的傅立叶定律，建立了主城对卫星城市基于交通通道的经济扩散模型．模型表明主城对卫星城市的经济扩散通量与其间交通通道的通过能力及两城市间的产业梯度呈正比．提出卫星城市规划应以经济扩散通量为依据，首先选择经济扩散通量大的城镇为卫星城市，对经济扩散通量小而与主城产业梯度高的周边城镇，可以通过交通通道建设来培育其向卫星城市发展．实例证明模型合理、实用．

Abstract: This paper analyzed the similarity between economic spread and heat conduction from central city to satellite city．It introduced the conception of economic spread flux，and established the economic spread model of central city to satellite city based on traffic passages by referring to the Fourer Role．Th e model indicates that the economic spread flux of central city to satellite city is in proportion to the capacity of traffic passages and industrial gradient between them ．It is put forward that the planning of satelite city should according to economic spread flux ．The towns with greater flux of economic spread should be the satellite cities of central city and the towns with smaller flux of economic spread but with higher industrial gradient can be developed into a satellite city by developing transpo rtation．The model is proved to be reasonable and practical by the example．
