  Background and Aim: Agricultural crop zoning is one of the types of evaluation that can be used as a model for land evaluation, better planning and management of land resources.Methods: In this study, to determine suitable places for barberry cultivation in Iran, different criteria and sub-criteria were considered. Implemented with the help of Expert choice software. Arc GIS software was used for spatial analysis and layer overlap and after data analysis.Results: The results of climatic, topographic and soil factors showed that the provinces of South Khorasan (Ghaen, Birjand), Fars (Shiraz and Abadeh), Hamedan, Arak, Isfahan, Shahrekord and Kerman are the best places to cultivate this crop. To express the amount of suitable or suitable areas for barberry cultivation in terms of area, different regions of the country can be divided based on the area of arable land of the country, which is 356858.1 square kilometers (35685810 hectares).Discussion and Conclusion: Finally, the results indicate designers in choosing a suitable place for growing barberry.

  Surface water is one of the main sources of agricultural water supply. Therefore, understanding and understanding of the water quality of rivers and their zoning based on the quantity of different elements will help us to make management decisions and reduce water pollution. The purpose of this research is qualitative zoning of Karun River in Khuzestan province in Masjed Soleiman to Ahvaz using fuzzy logic and hierarchical analysis (FAHP). For this purpose, qualitative parameters including: chloride (CL), sodium sorption ratio (SAR), electrical conductivity (EC), sodium (Na), and total dissolved solids (TDS) were used in November 1977. Qualitative parameters were first zoned using IDW interpolation method. Then, each of the obtained maps were fuzzy incremental linear membership function. Then, by preparing a questionnaire, paired comparisons between parameters based on the role of these parameters in determining water quality for agricultural consumption and based on AHP method, weight coefficients of each parameter were obtained. Came. Multiplying the weighting coefficients in the fuzzy layers and combining them, obtained a zoning map for agricultural use. The results show that the Gotvand, Arab Asad, Shahid Abbaspour and Gargar Shushtar stations are very suitable for agricultural use. Ahwaz and Malasani stations were located in a suitable area for agricultural use and Valiabad and Tang Dolab stations were located in a very unsuitable location for agricultural use.
