Although there are many researches on the life cycle of the resource-based cities, scientists have paid little attention to the evolution of the forms and spatial structures of these cities. Based on a case study of Fushun, a typical coal-industry city in China, this paper is designed to fill in the research gaps. It mainly includes:(1) Inquiring into the function of the natural conditions and the economic activities during the development of the resource-based cities, thus revealing the law of the formation of the coal-industry city's form.(2) Analyzing the differentiation between the resource development area and the industrial and commercial area in the whole resource-based city area and pointing out its specific form and spatial structure.(3) Pointing out the multi-polar linear structure of the coal-mining area and the multi-core structure of the industrial and commercial area in Fushun coal region, then interpreting the reasons. (4) Putting forward a general model of the evolution of Fushun's city form and its spatial structure and emphasizing that the interaction between coal industry area and de-coal industry area in Fushun coal region is the key to city's form and spatial structure. Moreover, evaluating the classical Friedmann.J Model of Regional Development and believing that this model is more practical.
