Abstract

Background: One of the main priorities of the agriculture section is the proper use of water and soil resources. Limitation of the cultivated lands, the increasing population and human need for natural resources have led to the use of soil so that in addition to achieving maximum crop, this source is protected for the future. In this regard, it seems that land suitability studies are necessary. There are several methods for assessing land suitability, among which Sys et al. (1991) method is most widely used due to the use of simple and classic models. In many land suitability studies, the uncorrected land index has been used. This has led to many differences in the results of different approaches of land suitability evaluation. The present study was conducted for assessing of accuracy and validity of the corrected indices of land suitability based on the determined relations by Sys et al. (1991) and Bagheri Bodaghabadi (2021).

Materials and Methods: In this research, field studies were conducted, then several profiles were drilled and described in Khanouk-Zarand, Bam and Rabor districts in Kerman province. Land suitability classes were determined by the four methods including 1-simple limitation, 2- number and intensity of limitations, 3- Khidir
