Based On GIS,RS And CA Technology Suburbanization Of Cities Simulation Study

The city is a special place,geographic,economic,social,cultural,regional entities, various elements of the humanities and natural elements of the complex of human material wealth and spiritual wealth of production,accumulation and dissemination of the center, and the associated impact on the extremely broad,and in the entire world urban development theory,generally believed that the development of cities must be experienced urbanization, suburbanization,reverse urbanization,and the development of urbanization process。Looks like the phenomenon is the world's urban development that will have to change the process,Suburbanization can say is the city reach a certain stage of development are inevitable phenomena , suburbanization process with the pace of development and urbanization of the impact of development,cause all national urban planners and policy makers widespread concern。Therefore launch suburbanization associated with the process of development form factor and the impact factor, In particular, based on the phenomenon of suburbanization in all aspects of the differences, and the adoption of the model and its development of modern technology for dynamic simulation model, Suburbanization of the theory and characteristics of urban development is of great significance。This paper attempts to use GIS technology RS technology and cellular automata theory framework out one pair of the whole process of suburbanization or part of the process of the simulation method, proceed to the northeastern region of Changchun City phenomenon of suburbanization trend forecast。This paper is divided into four main parts:The First and the second parts of the related technology in urban development of the theory and application of exposition made by these theories, Status and development process, we can understand the trends in urban development and modernization in urban development applications。The third part of the urban development related to the changes in the model and the formula introduced, These models and the application of the formula and related fields, and choose a suitable model and the formula for urban development suburbanization analysis。The fourth is in Changchun city of nearly 10 years of population, land and other aspects of development changes in order to determine their cities to suburbanization stage in the development of the situation, through GIS technology,RS technology and the integration of CA model used to analyze the cities of Changchun suburbanization, and through this method to forecast the development trend of urban planners and decision-makers through the relevant technical support。...
