Land suitability of Development Use using Current Models and new model of EMOLUP (A case study: Sepidan Township, Iran)

Negative environmental effects of urban growth have increased to such extent that is the largest threat in front of the ecosystem. This study was done in Sepidan county of Fars province with 3855 square kilometers. The main objective of this study is to evaluate and reform the ecological model of development of urban, rural and industrial in study area. Methods included Makhdoum method based on Boolean logic; the maximum limits proposed method (Boolean logic), arithmetic mean, geometric mean (EMOLUP), and weighting methods in 3 classes. The results showed in arithmetic mean & weighted sum mean method, most area was tending to good classes and in Boolean (Makhdoum & max limit) method most area was tending to weak classes, but the geometric mean method (EMOLUP) is among other methods. Also, based on assessment of the validity, geometric mean evaluation model (EMOLUP) is better than other models in estimation of environmental capability because of its simplicity. It should be noted that arithmetic mean method (OR), is the lowest accuracy of existing methods.
