This study aimed to analyse and evaluate the land suitability for certain fruit trees in Thuy Bang commune using GIS techniques in combination with a multi-criteria approach. At first, the databases for GIS analyses had to be developed. The data were obtained through scientific literature review, expert opinions, interviews, and professional officers. The suitability assessment in the studied area has been done in two ways: physical suitability evaluation and social-economic, environmental suitability evaluation. Integration of GIS and multi-criteria approach for land suitability analysis could be a useful methodology for further research in Vietnam. This approach makes it possible to select suitable land use types and crops for each administrative unit at community level. Keywords: Multi-criteria land suitability, fruit trees, GIS, Central Vietnam. 1 Introduction There are different factors influencing the productivity of fruit trees, including cultivars, cultivation technology and the growing conditions, but first of all information has to be collected about: - appropriate farming system and evaluation of land suitability, - appropriate and advanced cultivation methods, - use of growth regulator in order to stabilise the productivity in stress situation Land suitability evaluation and agricultural land use planning are very necessary and are the basic information for right decision making afterward [2]. In order to achieve high yield and high quality of fruit trees, it is very important to select the appropriate farming system [1] and to estimate the suitable land for certain crops [3], [4]. The constraints are mainly due to the lack of suitable land for the crop. In this regard, land suitability .
