INFLUENCE MODEL OF TRANSPORTATION BETWEEN CENTRAL CITY AND SATELLITE CITY TO URBAN SPATIAL EXPANSION
改进了传统引力模型，结合计算机模拟建立影响模型，分析中心城市与卫星城之间的交通对城市空间扩展的作用，发现交通发展使卫星城的城市扩展单元分配比例增加，而建成区和城市边缘区减少。
This paper developed the traditional gravitation model,established the influence model by using the developed gravitation model and the technique of computer simulation,analyzed the function of transportation between central city and satellite city to urban spatial expansion.It is improved by an example that the development of transportation between central city and satellite city make the allocation proportion of urban expansion units increase in the satellite city,but make it decrease in the built-up area and the urban fringe.The conclusion is obtained that the city space can expand to satellite city by developing transportation between central city and satellite city.
