Defining a certain range of land consolidation with support of GIS and visualization technology

摘要

In this study, we took the cultivated land of Shaoshan county in hilly area of south China as the study area, researched on defining a certain range of land consolidation with support of Geographic Information System (GIS) and visualization technology. It was carried out by four steps. First, we distinctly established the database of land use, terrain and Remote Sensing (RS) image. Second, we extracted the cultivated land data from the land use database, overlaid and analyzed it with the slope, Normalized Difference Vegetation Index (NDVI), the buffer of water source, the buffer of rural residential land. Third, we defined the principles of land consolidation, under these principle we defined the location and area of the certain range of land consolidation. At last, we eliminated the plots that were too small or separate to consolidate to high quality cultivated land. The results provided us reasonable basis for the land consolidation of hilly area of south China.
