Paper Abstract

Cultivated land resource is a key factor that affects the development standard of a region. By analysis of land use and land cover data in 2000, together with national geographical data, soil fertility comprehensive quality assessment data (1980), a GIS-based research is carried out on the quality analysis of cultivated land resources in poor areas. Firstly, data mining methods are used to gather the inter-relationships between the poor areas' cultivated land resources and its geographical background factors. Secondly, comparative analysis between the poor areas and non-poor areas is conducted to reveal the difference. Results show that the big difference exists in the basic natural features of the cultivated land resources between poor and non-poor areas. Although the quantity of cultivated land resource in those poor areas is not less than that of non-poor areas, the quality is lowly evaluated because of its high elevation, steep slope and earth surface roughness. Finally, after overlay analysis, the natural quality of cultivated land resources in poor areas is assessed according to their topographical and soil fertility features.
