Study and Zoning of Geographic Characteristics of Pistachio Cultivation in theZanjan Province

This study aimed to identify the geographical features of the pistachio tree planting، cultivation-prone are as in the province and zoning done. For this study، data from 12 synoptic meteorological stations، 5 climatologic and 15 rain gauge stations were used. Zoning of areas protoculture، the technique of GIS in terms of Bolein models and model AHP were used. Accordingly، by the use of software Arc/GIS، maps were sprepared by value. Then the Bolein matrix of each layer of software Idrisi was drawn up in order of significance of each element. The final map was obtained by integrating maps in Arc/GIS. The results indicate that the ranges of northwest and northeast، including two stations of Abbar and Mahneshan، due to geographic conditions have limited cultivation of pistachio trees. Therefore، there is potential for cultivation in these areas. It was found that the AHP model for accuracy and attention to detail، gives better results than the Bolein model.
