Evaluation of Agricultural Land Suitability: Application of Fuzzy Indicators
نویسندگان
چکیده
The problem of evaluation of agricultural land suitability is consid ered as a fuzzy modeling task. For assessment of land suitability, it is proposed to use fuzzy indicators. Application of individual fuzzy indicators gives oppor tunity for assessment of suitability of lands as degree or grade of performance when the lands are used for agricultural purposes. Using composite fuzzy indi cator it is possible to obtain weighted average estimation of land suitability. This theoretical technique is illustrated with a simple example.

Evaluation of land suitability for irrigation using fuzzy analytic hierarchy process
Use of new techniques to evaluate irrigation areas can enhance water use efficiency in agriculture. In this study, the fuzzy analytic hierarchy Process (FAHP) was used to qualitative land suitability for sprinkler irrigation and was compared with the parametric method. Evaluation based on parametric method showed that an area of about 1597.83 hectares (31%) of the lands was highly suitable (S1)...
