Adjustment And Protection Analysis Of Permanent Basic Farmland In Longchang County Of Neijiang

Since the ancient times, our country is considered as a major agricultural country,agriculture has always been the foundation of our national economy. As the needs ofthe national economic construction, the planning of local occupations of basicfarmland and other reasons, resulting in some basic farmland is transferred out, inorder not to reduce the number of basic farmland, carrying out a comprehensiveevaluation of the general arable farmland and transferring them to basic farmland isnecessary. In order to ensure national food production and promote the sustainabledevelopment of the agricultural, therefore, through the adjustments of the basicfarmland, transferring in and out the basic farmland by the quantity and quality, thendo some analysis, which has an important role of LongChang’s designated basicfarmland.Based the permanent demarcation of basic farmland construction projects ofLongChangXian, Neijiang City, Sichuan Province, using the characteristics of thearable land and basic farmland of LongChangXian to do research and analysis ofLongChangXian farmland adjustment, focusing on the analysis of the basic farmland,which is transferred in and out. The basic farmland which is transferred out mainlydeducts the occupied basic farmland of planning and new rural construction, thensumming the number of the transferred out basic farmland. The transferred in basicfarmland mainly has connection with the main principles of basic farmlanddemarcated, referencing the relevant information, to establish the evaluation system ofLongChangXian arable farmland which is selected to be the basic farmland. DecidingEach index score by GIS analysis module, using AHP to evaluate the quality of thefarmland, then determining the index weight. Finally, using the multi-factor weightingmethod to grade the arable farmland which is transferred in preferentially,determining the number of basic farmland enrolled finally.Through the analysis of the list for basic farmland balance delineation, obtainingthe result that the basic farmland which is transferred in increased in quantity, thequality of basic farmland which is transferred in and out is essentially flat. Bystudying the adjustment of the basic farmland in LongChangXian, it can be seen that, after the adjustment of the basic farmland, the contiguous extent is also increased, andthe protection area of basic farmland is not less than the basic farmland protectionarea which is planned.
