摘要

With the rapid development of economy and the improvement of urbanization level, the contradiction between urban spatial expansion and the decrease of cultivated land resources has become a hot spot in the field of geoscience. Based on satellite remote sensing images, the theory and method of urban spatial expansion and land scale prediction are studied systematically in this paper. This paper mainly discusses the technology of urban area boundary extraction based on remote sensing image, the method of area expansion analysis, the simulation method of cellular automata, the theory and method of urban land scale prediction. Methods of obtaining population are in urban built-up areas. First, in terms of making up for the inability of CA model to express spatial data, GIS technology has data preprocessing functions; Second, under environmental conditions, GIS technology has mature visualization functions, so as to make up for the situation that the CA model cannot immediately present and reflect the operation results. According to the characteristics of urban spatial expansion, combined with the research results in the field of urban can at home and abroad, this paper puts forward the construction scheme of urban spatial expansion can model integrated with gist he results show that the can model integrated with GIS can visualize the simulation results, and the simulation results can be analysed by GIS.
