Basic Farmland Demarcated Contrast Analysis Of The County

Human’s survival and the development cannot leave the land, with the populationgrowth and economic development, in order to ensure food security, social stability wecountry has been adopting the most stringent farmland protection system. And the basicfarmland is the essence of cultivated land, protecting the basic farmland has become thecore content of cultivated land protection. Reasonable delimit the basic farmland, is notonly to guarantee regional ecological security, also can promote the sustainabledevelopment of the region. So the research is of great importance to the protection of basicfarmland demarcated.Basic farmland demarcated in the general plans for land using is an important job，thisarticle in the new round of general land use planning revision after the completion of thework, In order to making Le An as an example, from the revision based on the plan ofbasic farmland demarcated and based on the permanent basic farmland demarcated twoangles, use statistical methods of analysis, prediction analysis, GIS analysis, comparison ofbasic farmland demarcated in quantity, quality, space layout of the three aspects ofdifference, discusses the realistic significance of the basic farmland demarcated, Topromote better implementation of the protection of basic farmland, to the perfection anddevelopment of basic farmland demarcated system designated work to provide thereference.This paper mainly includes the following several parts:(1) Discuss the background of the protection of basic farmland demarcated andsignificance, introduces relevant concepts and theory of basic farmland, and outlines theprinciples of delimitation of basic farmland, the source of the data and technical support,provide theoretical basis for drawn work.(2) Based on Le An city land use planning revision, general plans for land use todetermine the land as defined object, starting from the grain productivity into comprehensive consideration, to forecast the demand of basic farmland, using quantitativemethod to break down the amount of basic farmland, the quality of the analysis of basicfarmland and space layout.(3) Based on Le An permanent basic farmland demarcated changing in the secondsurvey in2011, on the basis of Mapgis as the platform, figure about the present situation ofland use plan and map of land use plan, design class diagram, then carries on the stack,withthe number,the use of analysis, slope and so on, determined to bring up the plot.(4)Based on land use planning revision of basic farmland demarcated and the pointof permanent basic farmland demarcated time is different, there exist certain differences inanalysis method, comparative analysis of the quantity, quality, layout of Le An city. Bothoverall consistent, consistent with Le An actual situation. Then propose suggestions andfurther protection of basic farmland protection.
