Abstract: With the aid of spatial analysis and simulation tool, such as space syntax and Cellular Automata (thereinafter referred to as “CA”) and on the basis of the typical example of downtown central area in Bengbu City, this paper carried out an analysis of the function aggregation and dispersion phenomenon of central area and a study of the spatial usage and distribution of different functional elements from the perspective of the geometric attribute of space itself as well as the logical relationship hidden behind the geometric attribute, based on which four spatial evolution models of four development stages of central area has been derived, and a summary and conclusion has been made on the basic characteristics and general rules of the transformation of central area. According to the study, the evolution of spatial form of central area and the evolution of its functional structure are highly homologous. In the construction and evolution process of central functions, the commercial and business service functions successively become the main contents of central function development; in the meanwhile, they also become order parameters that determine the transformation stages of central spatial forms. Subjected to the influence of the essential attributes of industrial advanced development itself, the central functional system is constantly adjusting its own functional structure. As a result, the functional structure, scale and functional elements of central area as well as the individual space usage and the integral space distribution are also changed, which further influences the overall spatial from of the central area; on the other hand, the changes of urban integral spaces determine the changes of locations of urban central areas, which further influences the value of land. This determines the proportion of investment in land capitals and building capitals in the process of central land development, and then determines the changes of land utilization approaches, which ultimately influences the distribution and structure relationship of central functions.
