The Research On Country Farmland Productivity Calculation For Modeling And Visual Analysis Of Results Of Hanbin District

Farmland productivity accounting is the deepening and continuance of farmland gradation,Agri-cultural land production capacity include theory capacity,can achieve productivity and practical cap-acity three levels.Through the establishment of standard of farmland classification unit grain yield and quality theory of natural function relation, standard index of yield and grain can realize the fu-nction between such index using the theory of separate accounting for grading unit yield and can implement production.Establish a basis for quality index accounting farmland natural farmland visi-on theory, a method of technical capacity utilization of agricultural basis to the current theory of agricultural productivity index accounting method,establishes the technology basis to the agricultural statistics calculation method of actual production of agricultural technology.Combined with the acc-ounting study farmland productivity selection method,this paper on the coast area of Hanbin farml-and productivity calculation actual case studies.And with MAPGIS and ARCGIS software mapping function make each capacity distribution,analysis Hanbin waterfront district capacity structure and spatial distribution layout;Drawing Hanbin waterfront district agricultural land use latent capacity an-d strength theory can realize diagram and use latent capacity and strength figure,analysis Hanbin waterfront district agricultural land use value and development value.For the final Hanbin waterfrot district capacity to analyse the result of the accounting application and some suggestions,hoping f-or the development of agricultural land can actually a role.
