Evaluation results showed that Hau Giang had four major land groups with 11 land mapping units; alluvium land group accounted for % of natural area. From the map overlay has been integrated 28 land units. Basing on 44 LUTs surveys was selected for 16 LUTs to have development prospects to evaluate land suitability. | Journal of Science and Technology 54 (2A) (2016) 104-111 EVALUATION OF LAND RESOURCES FOR HAU GIANG PROVINCE’S LAND USE PLANNING ADJUSTMENT Nguyen Thanh Quang*, Đang Trung Thanh Faculty of Resources and Environment, Thu Dau Mot University, No 6 Tran Van On street, Phu Hoa ward, Thu Dau Mot city, Binh Duong province, Vietnam * Email: ; thanhdt@ Received: 1 April 2016; Accepted for publication: 15 June 2016 ABSTRACT Hau Giang is one of 13 provinces in the Mekong Delta. Total land area is 162,171 ha (statistics 2014), agricultural land is 141,217 ha accounting for % of natural area. To exploit the reasonable land and provide a scientific basis for adjusting the land use planning to 2020, the evaluation of land resources in Hau Giang was carried out. To apply the land evaluation methodology of FAO to research on natural conditions, socio-economic related to land use to evaluate land resources as well as to apply for geographic information system (GIS) and automatically land evaluation system (ALES) gave results positively, quickly and efficiently. Evaluation results showed that Hau Giang had four major land groups with 11 land mapping units; alluvium land group accounted for % of natural area. From the map overlay has been integrated 28 land units. Basing on 44 LUTs surveys was selected for 16 LUTs to have development prospects to evaluate land suitability. Land use was divided into 5 main groups: alluvial land belonged to riverside Hau, slightly saline land was not submerged and was shallow, and low-lying saline land was flooded and saline land was salty. To combine with evaluating the current state of land use, productive techniques and socio-economic development needed supplementing of land use planning by 2020 as follows: (1) agricultural land is 141,217 ha ( %); (2) non-agricultural land is 20,918 ha ( %) and (3) unused land is 36 ha ( %) of natural area.
