Remote Sensing Monitoring Urban Expansion And "smart Growth" Strategy Analysis Research

In recent years, our country in the pace of urbanization, many large and medium-sized cities in different degrees of urban spatial disorder of spread, or called city "suburbanization". Facing our country’s basic conditions, city "suburbanization" continues to expand will cause a series of land use relevant social economic problems. If you want to keep city sustainable development of regional economy, it is necessary to implement effective city planning methods and management methods, to blind land development phenomenon of scientific regulation. This paper takes Kunming city in2004,1996and1988three time remote sensing images as the original data, through remote sensing monitoring information extraction, combined with the Kunming city is faced with in development of land use, and Kunming in the development process of city expansion problems, based on the theory of smart growth strategy of the United States of America’s core and connotation understanding, reference the United States State in implementing smart growth planning after the success of understanding, the spirit of building harmonious society and economical society objective, scientific, economical, intensive use of land and other basic concepts, the suit one’s measures to local conditions in the study area city expansion remote sensing monitoring spatial structure are analyzed, then put forward the corresponding expansion of the primary control program.The paper studies the main results are as follows:(1) Summed up the expansion of our city the existing problems and the development of Kunming city in some of the disadvantages, discusses the domestic and foreign scholars on the expansion of the city and smart growth theory and research status of the United States of America smart growth theory in local practice and research progress.(2) The use of remote sensing classification research was carried out in area city expansion information extraction, for the follow-up study smoothly laid a foundation,1988to2004in the study area of each land use type space changes and land use quantitative features of the detailed analysis of the. (3) Application of land use transfer matrix method was used to determine the study area of land from a land use types into another kind of land utilization type area number and transfer direction.The single land use type dynamic degree and land use type change trend and state index models respectively from three aspects to research land use dynamic attitude evaluation, to make clear of the land use type to scale increase trend toward the direction or to reduce the scale of development trend.(4) The application of GIS spatial analysis technology, the study area of construction land expansion was carried out specifically to deepen research.Using spatial quadrant range analysis method, calculation of the study area in the1988-2004years of construction land expansion area in specific directions, as well as the city expansion intensity index and dimensions.(5) Consolidation summarizes the city expansion type and city expansion model, analysis of the study area of the city expansion type and expansion mode, in order to "smart growth" strategic vision for starting point, the initial construction of the study area to city expansion control scheme.
