Assessing land suitability for sustainable agricultural production model conversion intergated multiple criteria from various fields (natural, economic, social, environmental), asc a multi-criteria decisiontools. In this study, a GIS and MCA integrated model was applied to evaluate land suitability for a proposed sustainable agricultural production model conversion in Ta Dung National Park. The process was carried out as follows: Firstly, sustainable factors were identified using the FAO method (1993b, 2007), and the AHP-GDM method was applied to calculate the weight of each sustainable factor. Secondly, specialized information layers were constructed in the GIS system for each factor. Finally, the specialized information layers were overlaid, and the suitability index (Si) was calculated for each region using the weighted average method, and Si was classified to identify the adaptive region. From there, a sustainable agricultural production model conversion was proposed.
