Abstract: 

GEOGRAPHICAL INFORMATION SYSTEM (GIS) TECHNOLOGY IS A TOOL FOR COLLECTION, MANAGEMENT, ANALYSIS AND REPRESENTATION OF LAND INFORMATION. GIS HAS A SUITABLE ABILITY FOR MODELING, ALGEBRA AND BOOLEAN OPERATION THAT NEEDED FOR LAND SUITABILITY EVALUATION. IN RECENTLY YEARS, THIS TECHNOLOGY MADE REVOLUTION IN ANALYSIS, DECISION AND RESOURCES MANAGEMENT. FOR A SPECIAL PURPOSE, LAND EVALUATION IS NEEDED TO INVESTIGATION OF SEVERAL CRITERIA THAT NAMED MULTI-CRITERIA EVALUATION (MCE). FOR MANY YEARS THIS METHOD IS USED WITHOUT GEOGRAPHICAL INFORMATION SYSTEM TECHNOLOGY IN SOIL SCIENCE FOR LAND SUITABILITY EVALUATION. INFACTLY, THE MAIN PURPOSE OF LAND EVALUATION IS INVESTIGATION OF SUITABILITY OF SEVERAL SOIL UNITS WITH CONCENTRATION PHYSICAL, ECONOMICAL AND ECOLOGICAL PROPERTIES OF RESOURCES FOR SELECTION OF SUITABLE ALTERNATIVES. THE PURPOSE OF THIS STUDY IS APPLYING LAND INFORMATION FOR EFFECTIVE CRITERIA ON LAND SUITABILITY ALMOND PLANTATION IN CHAHARMAHAL VA BAKHTIARI PROVINCE. THE RESULTS OF THE MULTI-CRITERIA EVALUATION METHOD REVEALED THAT PARTS OF THE LANDS ARE HIGHLY SUITABLE AND THE PERCENTAGE OF THE SURFACE AREA WITH MODERATE SUITABILITY CLASS IS HIGHER WITH RESPECT TO THE RESULTS OF THE OTHER USED METHODS. THE MULTI-CRITERIA EVALUATION METHOD IS MORE FLEXIBLE COMPARED WITH THE OTHER USED METHODS. THE REASONS FOR THIS DIFFERENCE ARE WEIGHTING THE CRITERIA AND PIXEL BY PIXEL EVALUATION DONE IN THE GIS. MULTI-CRITERIA EVALUATION METHODS ARE NOT COMPLICATED AS FAR AS CALCULATIONS ARE CONCERNED AND CAN BE USED EASILY IN THE GEOGRAPHICAL INFORMATION SYSTEM. BECAUSE OF USING EVALUATION MATRICES, MULTI-CRITERIA EVALUATION METHODS ARE EFFECTIVE IN ACCELERATION OF THE OPERATIONS, REDUCTION IN EXPENSES AND FACILITATING OF THE EVALUATION.
