Land use planning is one of the basic principles of sustainable development in a region and in a *** main objective of this paper is to test a new model of land use planning in order to evaluate ecological suitability and prioritize different land uses in Jahrom County placed in Fars Province,*** two main steps were prepared for the new model of Eco-Socioeconomic Model of Land Use Planning(EMOLUP).Step 1 includes ecological capability evaluation of different land uses including forest,rangeland,agriculture,conservation,and *** step is composed of the geometric mean method instead of the Boolean method;and step 2 includes land use planning and prioritizing for the various uses mentioned *** step is composed of intersecting ecological capability maps and land use planning,based on two scenarios(economic and social).It was compared with qualitative and current quantitative ***,current land use is employed for calibrating and modifying the *** results of ecological suitability evaluation showed that the EMOLUP model has more accuracy in the process of comparison than other current ***,revised method using the geometric mean(with overall accuracy>72 and kappa index>0.55 for all land uses and rangeland with overall accuracy=32 and kappa index=0.02)is better than Boolean models,and the method of the calibrated geometric mean(with overall accuracy>87 and kappa index>0.73 for all land uses)is the best among different used *** should be noted that the arithmetic mean has the lowest accuracy(with overall accuracy<45 and kappa index<0.24 for all land uses).Also,the results of prioritizing and land use planning showed that the quantitative method with two socio-economic scenarios(result based on average of EPM erosion model=0.3 that means 30%of modification in whole study area land uses)is the best method for land use planning in the study area.
