Methodology: In this regard, the effective agro-ecological data in different phonological stages of Aloe Vera plant, including minimum and maximum temperature and precipitation as unstable factors, and elevation, slope, aspect, soil and salt domes, as stable elements in the assessment of susceptible areas Aloe vera cultivar was used. Using the Fuzzy Gama and Fuzzy Multi-criteria Decision-making System (FMCDS) technique in the GIS, to determine the appropriate sites for cultivating Aloe vera plants in Hormozgan province
Findings: The results of the implementation FMCDS were that the minimum temperature and soil factor had the most effect on the agro-glimatic feasibility of Aloe Vera cultivars. While the factor for the slope played the least role in this field. The results of the GIS overly of the criteria based on the Fuzzy Gama in Hormozgan province showed that 0.35 of the provincechr('39')s area has good and excellent cultivation capacity for this plant. These areas generally coincide with the low-slope and warm areas of the southern part of the province. Due to the coherence of the composition of the texture and the proper depth of soil, the soils of Arid soils and Anti-soils, which have a suitable drainage for the cultivation of aloe vera, can be favorable areas for development of Aloe Vera crops in the province. While in the northern parts of the province, the slope effect, lack of Aloe Vera plant thermal needed degree days, seaasonal and diurnal thermal varialbility, weakly yield the product, and the development of Aloe Vera farms in these areas is not recommended. The Results indicated in 2 climate Change scenarios (A2 and B1) the agro climatic zones of Alo-Vera significantly changed in compared to current climatic condition. The results indicated that under A2 scenario the spatial changes of Agroclimatic area of Aloe-Vera were greater than other scenarios.
Discussion and conclusion: The main output of this research is the production of Aloe Vera clultivation agro-climatic feasibility map in the province which has provided the sites and areas favorable for the cultivation of this expensive medicinal plant.
