In recent years, Vietnam is very interested in the investigation classification, soil mapping, evaluating Suitable land, which has been an important contribution for enhancing the quality of plans for agriculture land use planning. It has been also the primary goal to synthesize and build the plant restructuring orientation associated with the restructuring of land use.
Through the preliminary evaluation regarding the socio-economic conditions, the soil as well as the farming practices at Thuy Bang Commune, Huong Thuy Town, Thua Thien Hue Province, Vietnam, it shows that this is the great potential land which is to develop the peanut production, and the inhabitants who live there are also increasingly expanding the planted peanut area in recent years. However, the determination and the suitable ability partition which is the scientific basis for the implementation of land planning to develop the planted peanut is yet to be processed. The study combined with the land evaluation according to FAO and GIS technology application, specifically is ArcGIS software, which are the implements to build the thematic maps and superpose these maps constitute the land unit map, then classify appropriately for peanut planting in the studied area at present and in the future. The research results have identified that Thuy Bang Commune has 28 land map units; the current classification for peanut planting shows that the studied area appears only at low and suitable medium accounted mainly. The research has been proposed to the developed area and distributed specifically to every other area and each land unit for the peanut planting of Thuy Bang Commune. The proposed research is very important and it is the scientific basis for the reference planning of the agricultural development in the future of Thuy Bang Commune, Huong Thuy Town, Thua Thien Hue Province, Vietnam.
