Results Complement The Cultivated Land Quality Level

Cultivated land quality level results complement is the important part in the surveyof land resources, the implementation of the work is the basis of the land administrationlaw of the People’s Republic of China. Through mastery and scientific quantification offarmland quality and distribution, the implementation of government land managementby the numbers is given priority to, gradually to the change of quantity, quality,ecological coordinated development, build system of cultivated land quality gradeevaluation of our regular surveys, cultivated land quality level and production capacityof the annual report system, strengthen the management of cultivated land quality andcultivated land resource security, for the implementation of cultivated landcompensation system, the realization of regional cultivated land, cultivated landproduction capacity calculation of dynamic balance, agricultural land transfer andprovide basis for protection of basic farmland, and to promote the development ofagriculture, rural areas and farmers rich, establish a conservation-minded society hasvery important role.In this paper, as MianXian for example, in view of the unified arrangement by theministry of land and resources at the county level of cultivated land quality level resultscomplement work study, in accordance with the "regulations of agricultural land qualityclassification"(GB/T28407-2012),"standard of farmland classification database","ShaanXi province farmland quality grade results complement work manual of thecounty level stipulated by the technical route, in2006, the acceptance by the county, onthe basis of agricultural land grading results, carried out based on the second nationalland survey of the cultivated land quality level results complement research, and landuse status quo investigation of corresponding, scientific quantitative condition andspatial distribution of cultivated land quality to improve the quality of cultivated landquantity integration management. The object of study for MianXian25township (town)all of the cultivated land, cultivated land area of41156.67hectares (617350.1acres).This study mainly uses the factor method to land use change survey in2010status of the graph is reproduction, the related parameters have been determined in thefarmland classification work, grading factors and weight analysis, on the basis ofmulti-factor comprehensive analysis and calculation of the natural quality of specifiedcrops in each classification unit, and according to the light warm production potential(climate) index, the output coefficient of farmland natural quality index calculation,update the land utilization and economic coefficient, the calculation of cultivated landuse index and economic index etc, on the basis of equal spacing method, dividedprovince farmland natural quality, etc. Don’t use economic basis etc in the province andnational index balance transformation rules, calculation of grading unit of national level,such as index, according to the rules such as don’t divide spacing, determine nationalnature quality use and economy. And is applied to research MianXian basic farmlanddemarcated in the general land use planning revision, land reclamation, cultivated landquality evaluation of dynamic balance, etc.
