Abstract


The balance of arable land is a dynamic concept balancing to ensure that the total amount of cultivated land in China in accordance with the principle of comprehensive agricultural production capacity without reducing the use of agricultural piece j results and methods of land classification, within a certain range of time series and given area, new arable land and the The reduced farmland equal to the number of quality equivalent to achieve fill the quantity and quality of arable land accounts for double-balanced to protect the country's food security. Fill the quantity and quality of arable land in order to better the country promoting balance work, need the help of the geographic information system, empty the Japanese J database-oriented object programming language technology, the establishment of a homeland-oriented management of arable land accounted for complement The number of mass balance information system, promote the arable land accounts complement the quantity and quality of balanced management of information technology and automation. This paper first introduces the establishment of arable land accounts for the significance of the complement number of mass balance information systems, characteristics, and an overview of the research status quo at home and abroad in this field; then discussed the balance of arable land, agricultural land classification positions due to reunification additional land level translation of the concept, content, and asked the three mutual convergence relationship Ji laid the theoretical foundation for the system; subsequently elaborated the Component (IIS development, structure, specific application, and a brief introduction to the ArcGIS the functions and characteristics of the components of Engme. text arable land accounts the complement A Heng T. characteristics and needs, determine the goals and tasks of the system proposed based a Component (3IS system solutions, detailed design the overall structure of the system and the database model, and based on ArcGIS Engine c #. NET Ji made a set based on the the component GIS arable land accounted fill the quantity and quality of balanced information systems. main contents of this paper are: (1) Based on G3eodatabase model study spatial database conceptual models, logical and physical models of design, complete land use data, the check of the agricultural land classification data warehousing, and to study spatial database and attribute database logic associated design, based on the entity relationship model ( E-R) design attribute database; (2) component-based (31S and unified national land supplement grade conversion model. Arc (31S technology platform, NET Ji sent box pear, research and development of the amount of arable land accounts complement mass balance information systems; (3) North Water Transfer Project is selected the northern section of the entry port engineering simulation analysis, the use of all-solid unified land supplement grade conversion coefficient of arable land accounted fill the quantity and quality of balanced information systems, North Water Diversion Project The northern section of the project land use analysis and forecasting analysis and ex situ occupation and retrieval, and to explore how the state overall arrangements for major construction projects complement allow farmland cultivated ex situ accounted fill the quantity and quality of double-balanced.
