Research On The Division Of The County Main Function Evaluation And Control Based On GIS And RS

The main functional areas,as defined by the National Development and Reform Commission issued the document is:Depending on regional resources and environment carrying capacity,existing development density and development potential,in accordance with the principle of coordinated development of the regional division of labor and has designated certain body functions Positioning of spatial units.County planning as the main functional areas of regional spatial planning system,an important part of the region is between another type of land spatial planning and town planning urban planning above.Based on the main function of county zoning requirements,the use of GIS and RS approach to the main functional areas of the study area were reasonable division of the main functional areas and the establishment of the county dynamic monitoring system for post-implementation management services division to provide space for regulatory services.The main results obtained in this paper include:1)data collected through the division processed and analyzed and compared to the findings of the study area of remote sensing image based on DEM terrain correction after extracting vegetation coverage data than traditional vegetation cover degree extracted data with "The second national land survey" more accuracy and objectivity of the data.2)comparison of the methods evaluated by a single index,Kriging better reflect regional spatial correlation between variables,making the final division of the functional areas are closer to reality.3)using three methods in process into functional areas of:dividing each index is calculated based on the results,the use of GIS platform for easy zone divided and special zoning scene mapping,effective combination of these three methods of making the entire division The process is more rigorous and scientific.4)After the main functional areas of the study area is divided,the index factor for real-time monitoring,whether divided functional areas put in place the regulatory space-based RS to provide follow-up services for the main study functional areas of the study area.5)Develop a county main functional areas of dynamic monitoring and management service system to achieve the study area in the county as the basic unit of the base map basic operation,spatial data queries,and other functional areas of space control capabilities for the main functional areas of the study area is divided,provide the basis for implementation and control.
