The Delineated And Layout Of The291Farm Of Basic Farmland

China’s arable land is a scarce resource,"cherish and make rational use of every inch of land,clearly in the overall land use planning to determine the number of basic farmland designated basicfarmland protection areas. However, in recent years, with the rapid development of economicconstruction, the cultivated area quickly reduce the protection of basic farmland still need tocomplete the task, and the enormity of the task unabated. Some scholars believe that this is notonly related to the policies and imperfect system, but also by the lack of technical supportconstraints. Basic farmland protection is not only an urgent government work, and also has aserious scientific content. However, in the actual basic farmland protection planning operation,some local governments are often from the immediate interests, to meet the construction land inthe first place, by higher authorities in order to accommodate the building of towns and villages, tomeet investor demand for land, agricultural to protect indicators, always "zoned inferior not zonedexcellent", such as: the remote, complex terrain, poor soil and water quality arable land designatedas basic farmland, and even some steep slopes should be returning farmland to forests has alsobeen designated as basic farmland range.Land of natural resources and an important place in human development and survival. Chinais at an important historical stage of development of rapid economic development, per capitaresource shortages, increasingly prominent contradiction between the ecological resources and the,basic farmland is high quality and high yield farmland, the law clearly demarcated by basicfarmland protection areas of arable land. Our the basic farmland relationship to the fooddevelopment, social stability, and National daily life of the peasants’ vital interests, in particular,China is in the stage of development of rapid population and rapid social and economicdevelopment inevitably will occupy some farmland, affecting food security Therefore, China’sgrain production is not optimistic. In this situation is not optimistic, especially the protection ofbasic farmland protection of arable land is a top priority of the work,"an insurmountable red line.Already have work experience and study and explore the results in such a social context, drawing,full system delineation of basic farmland, explore. This article by the connotation of basicfarmland, concepts and procedures delineated science definition proposed delineation of theevaluation method of the basic farmland protection areas based on the quality areas delineatedmeasures for China land reclamation, land management, to improve farmers’ income, agricultural land rational development to provide sound scientific support and basis.Empirical studies have shown that the overall land use planning is not a simple determinationof the number of basic farmland by higher authorities to subordinate issued a basic farmlandprotection indicators, the subordinate implementation planning department to simply make up thenumbers to complete a process. Consider the need for scientific arable land conditions, economicand social development needs of administrative intervention, human factors, and many otherfactors, therefore this article from the three levels of the quality of the natural conditions of thearable land, geographic conditions, arable land around influencing factors selecting slope thedistance to the rural settlements, climate, soil, water infrastructure, arable farmland to the road themain road distance the farmland adjacent land suitability degree seven indicators to establish ageneral farmland index system as basic farmland and the use of GIS technology to extract spatialattribute data for evaluation; to use interval assignment method based on the quality of cultivatedland, the quality and location of the arable land of the pros and cons Sort; Finally, GIS spatialanalysis functions designated basic farmland. In order to make scientific decisions.
