Spatial planning method for the basic farmland protection based on the farmland classification

Basic farmland has a direct influence on food safety. Farmland protection is virtually basic farmland protection. Aiming at the problems in basic farmland protection planning at present and the demands of land use planning revision, considering the principle of land use data sharing, the full using of the results of farmland classification in basic farmland protection planning was discussed, which is that the farmland integrated grading was considered as an important factor in the process of spatial distribution for the basic farmland. Based on the food supplies safety and the meaning of basic farmland, the technical method of which the decision-making model of basic farmland protection planning is the core was established. By the method of entropic coefficient, ideal points and GIS technology, a techno-route was established for the basic farmland spatial planning based on the Mapbasic programming and trying on the Mapinfo, the process from the analysis of the professional model to the auto-making of the planning map was accomplished, the decision-making support and visibility was realized for the basic farmland planning, which make the planning results more scientific and reasonable. Satisfying results were obtained by the demonstration in Jinan city.
