Study On Red Line For Ecological And Arable Land Protection In Land Planning Layout

Since the reform and opening, the national economy maintained thirty years of rapid growth, has made remarkable achievements. But the speed of industrialization and urbanization on the natural environment caused by heavy pressure, construction land and contradictions farmland protection, social and economic development and natural ecological protection has become more prominent. Therefore, how to scientifically and rationally preparing land use planning and coordinated development and protection of the relationship between land use to achieve sustainable development is one of the fundamental proposition of building a socialist ecological civilization.Taking Guigang urban area as the object of study, geographic information technology as the main means of flexible use of ecological function zoning method, the functional importance of ecosystem services evaluated on the basis of ecological sensitivity of the results of the evaluation, the evaluation results in the two the most important areas for ecological land as a red line. Farmland Quality Grades update on the results of field research and build the prediction model estimated the number of red and cultivated land protection quality red line, combined with the protection of arable land red line delineated based on ecological land red line, red line in ecological land and farmland protection red science designated based on the regional land-use planning studies. The main contents and conclusions include:(1) ecological land designated red line covering the key areas Guigang urban ecological protection. Guigang total urban ecological land delineated six red line. This six ecological land red line with a total area 123243.72hm2, accounting for 34.74% of the total land area of Guigang downtown.(2) the protection of arable land red line designated to meet the basic food needs Guigang downtown. By forecasting models calculate the total amount of Guigang urban minimum food requirements, based on utilization of arable farmland protection delineated seven red line. This seven of arable farmland protection red co 84970.35hm2, accounting for 58.89% of the total area of cultivated land, accounting for 73.48% Guigang downtown high utilization of arable land, can meet the minimum requirements of cultivated land quantity and quality of cultivated land Guigang downtown, guarantees Guigang urban food security.(3) protect the ecological red line and the red line of arable land to delineate the limits of scientific services in land use planning, help to optimize the layout of urban land use Guigang. Article Guigang urban land use layout is divided into 10 districts, including the red zone ecological land and farmland protection red zone, it can ensure that the development and survival of red red safety security for Guigang urban ecological function security and food supply security and lay a solid basis, reflecting the priority to the protection of ideas, in favor of Guigang urban sustainable development.
