Based On The Rs To The Extension Of The Urban Land Utilization Dynamic Monitor And Driving Force Analysis

The city is located in convenient transportation environment, covering a certain area ofthe dense population and housing combination.With the rapid economic growth，acceleratethe process of industrialization, rising living standards to improve the impact of rapidpopulation growth and other factors, prompted the city is gradually increasing, andcontinuously expand outwards. Therefore, strengthening of urban expansion on landresources to improve the land management measures to improve land utilization efficiency,and provide scientific and rational and sustainable use of countermeasures andrecommendations have a positive and practical significance and strategic significance.Remote sensing image analysis and simulation of urban expansion, land-use changeresearch data sources, with accurate, rapid, periodic real-time access to the advantages ofurban land status and its changes data. The adoption of these technologies was not at thesame time, accurate information on urban expansion phase for the dynamic monitoring ofurban change and planning regulation to provide scientific technical parameters.Fuzhou City, built-up areas in the study area, analysis of the various periods of urbanexpansion, combined with socio-economic statistics, the use of gray correlation analysismethod to study key findings:(1) To Fuzhou City, the use of the2000,2004,2008three-phase remote sensing imagesupervised classification and extraction of urban built-up areas. Validation of theclassification accuracy to meet the monitoring and analysis of the dynamics of spatialdevelopment of Fuzhou City.(2) Fuzhou City urban expansion,land use structure, extension strength of4wereanalyzed to reveal the Fuzhou City extended morphological characteristics and itsevolution, and studies have shown that: Fuzhou urban expansion characterized as"East suppression, South Extension, west, and North.(3)To establish the index system of the driving force of urban expansion, the use ofgray correlation analysis, analysis of the link between urban expansion and the drivers ofFuzhou City, come to the main impact factor. Studies have shown that: the main factorsaffecting the urban expansion for the level of urbanization, GDP growth, per capitaannual disposable income, public facilities, theper capita living space.
