GIS Environment Agricultural Land Classification Study

At present, the population-resources-environmental crisis is further exacerbated, and how to resolve this issue is the focus of today's study. In the population-resources-environment system, land resources in the most basic position. To mankind's survival and development, we must land for sustainable use of research and evaluation. And all agricultural land is the use of land resources, as the basis for sustainable social development. Classification of agricultural land is to achieve farm management from "quantitative management" to "quality management" "manage and protect the ecological environment," a higher level of the most effective technical support; national land resources survey of the important components; is to substantiate and refine the "digital territory" an important element.This paper from different periods of domestic and international agricultural research to classify the situation and development trend, combined with GIS technology, Agricultural Land Classification of the basic concepts and principles were described. "Agricultural Land Classification of order" as the standard "Shaanxi Provincial Agricultural Land Classification and pilot county Evaluating Technical Program" (2006) and "Shaanxi Provincial Agricultural Land Classification manual "for the technical basis According to the Agricultural Land Classification experience, According to the Shaanxi Provincial of the actual classification of the work to establish model detailed descriptions of the agricultural land classification of data storage work. And Wubu County, from basic data collection, classification, selection factors, Establishment of a system to the GIS geographic information system software platform based on the base map compilation, Classification unit classification, spatial database and database attributes and links to the establishment, Classification and the final index calculated statistics about the outcome of final plans have been made detailed and comprehensive briefing.Through the completion of the above work, Wubu County is divided into four, and so on to other, The next phase of its classification and valuation basis for the work of preparing, Wubu County, as well as the relevant departments in the formulation of agricultural development policy and agricultural resources development and utilization, Management will provide important theoretical basis for and significance.
