  Abstract: Saline intrusion is a serious threat to economic, social development and environment. It is caused by human activities and natural disasters including climate change. This problem is increasingly affecting the ecological zones and agricultural systems, especially in the coastal low-land areas of the Mekong Delta. Therefore, sustainable agricultural land resource management is an urgent requirement as Can Giuoc district, Long An province, a typical area of Mekong Delta, Vietnam. In this study, the results based on figures and parameters in observing stations showed interpolation of elevation classification of water levels in the case study according to sea level rise: 1 m; 1.2 m; 1.6 m; 1.8 m; 2 m; 2.2 m. Then, using ArcGIS Desktop supplemented related objects of DEM layer combining practical investigated results (from measuring salinity data of station system) to build the saline intrusion map. From the result, research will be advance to generalize and predict specifically to areas where are salty according to different levels as a background to suggest, orient suitably and sustainable solutions for cultivating of agricultural land where is in the condition of climate change and sea-level rise
