STANDARDIZED DATABASE OF LAND EVALUATION FOR AGRICULTURAL PRODUCTION

This research has built and standardized database of land resources, integrated interdisciplinary fully with the land evaluation framework of FAO. On this standardized database was proposed assessment of suitability with 3 main land use types (rice, vegetable and flower cultivations) in former Ha Tay province’s districts (a part of new Hanoi), serving the proper land use, planning and management. The application of remote sensing methods and GIS showed flexibility in digital data handling, storing, extracting and providing information fully and quickly on the thematic map. Soil map and map of suitability for 3 land use types, presenting the result of land evaluation in 1: 50,000 scales, were established according to VN2000 projection (2012). On soil maps, in addition to the soil type elements, shows the results of natural factors such as slope, topography, soil depth, soil texture, stoniness and depth of gley.
