The study of adaptation of Yazd settlements with spatial desirability using the Dematel Fuzzy method, Fuzzy ANP

The cities are severely affected by the natural environment around with which they shall be adapted. Yazd Province is located in a hot dry climate and it could be survived and adapted with the hard dry natural environment. To have this adaptation continued, a proper planning should be done to set desirable settlements to develop urban areas.The research goal is to examine Yazd Province adaptation with desirable locations. The methodology was decision techniques using Geographical Information System (GIS) and fuzzy models. In this research, the Province adaptation with spatial desirability was measured with environmental, social and economic features by eleven indicators. The importance and impact of the criteria were determined by Fuzzy Dimethyl Method. The final map to determine and compare spatial desirability was created by two methods of Fuzzy Compilation and Linear Weighted Composition (WLC). In the Fuzzy method, the layers were first fused and standardized, then, the layers were performed on the weights obtained from (FANP) in each of the Fuzzy operators (0.5 GAMMA, AND, OR). In the second method, the WLC layers were categorized based on the value given and were obtained in the final weight. The results showed that the AND fuzzy operator contains a more rigorous approach than other OR operators and 0.5 GAMMA. The largest area is about %87 with very too low adaptation. In the OR method, the minimum precaution is about AND and GAMMA 0.5; the area of %38 has a too low and low adaptation and an area of %14 with great adaptation. There is a lee caution in 0.5 GAMMA method than the caution in AND method. 0.5 GAMMA is more rigorous than OR and determines the area of %84 as a too low adaptation and the area of %2 as a high adaptation. In WLC the interaction of results does not considered and it only combines the cell values. In the obtained map, the area of %90 is considered as a too low adaptation and the area of %1 is considered as a high adaptation. The orientation of cities’ development was suggested based on the done modelling and the rate of rigorousness.
