Extended Abstract
Introduction: The expansion of sustainable agriculture and the proper use of the country's water and soil resources require the selection of suitable plant species that are compatible with the climatic conditions of the country. Therefore, the optimal use of natural resources through the planting of plants compatible with the conditions of the region can guarantee human health, the sustainability and progress of sustainable agriculture, in fact, for the optimal use of land, the issues of water, soil and air cannot be analyzed separately For such researches, a framework such as zoning is proposed to plan, operate and properly use homogeneous pieces of land. Rosa damascene has a low water requirement and is highly adaptable to dry conditions. Considering Iran's climatic and geographical characteristics, the expansion of the cultivation of the Rosa damascene plant has gained double value.
Materials and methods: Ardabil province in the north-west of Iran, with an area of 17,953 square kilometers, covers 1.09% of the total area of the country. Its geographical coordinates are between 37 degrees 25 minutes to 39 degrees 42 minutes north latitude and 47 degrees 3 minutes to 48 degrees 55 minutes east longitude. In the current research, using climatic criteria (Growth Degrree Days, annual precipitation, precipitation of the growing season, average temperature of the growing season, sunny hours of the growing season, and altitude) The growth of each plant starts from a certain thermal threshold, and the growth threshold of the rose is 2.5 degrees Celsius and the fuzzy TOPSIS method and the ANP network analysis process, the stations of Ardabil, Khalkhal, Parsabad and Meshginshahr have been selected for the cultivation Rosa damascene. The growth of each plant starts from a certain thermal threshold, and the growth threshold of the rose is 2.5 degrees Celsius. The steps of the TOPSIS technique include forming a decision matrix, forming a scale-free matrix, determining the Euclidean distance and choosing the best option, and the steps of the ANP method include creating a network structure between criteria, options and the goal, pairwise comparison of matrices and Formation of super matrix and selection It is the best option. In this model, each cluster and elements have a mutual relationship and the relationship of each criterion and clusters is checked with each other and they get a score between 1 and 9. The zoning and final drawing of the maps were done in the Surfer software environment and interpolation was done with the Radial Basis Functions method.
Results and discussion: After weighting the effective parameters for the cultivation of Rosa damascene based on TOPSIS models and the ANP network analysis process and performing modeling and analysis of climate data, the final interpolation map for Rosa damascene cultivation was prepared based on the climatic potential and abilities. The results showed that in prioritizing the options for growing roses using the TOPSIS and ANP methods, the priority of the options is related to Meshgin Shahr, Khalkhal, Ardabil and Parsabad stations. In fact, the unrestricted lands include Meshgin Shahr station, which is the best place for cultivation due to its good climatic capabilities, and Ardabil and Khalkhal stations have low and medium restrictions for cultivation. The lands of this station have relatively weaker conditions than is the MeshginS hahr station , but good performance is expected from it. Parsabad station has very limited lands, which according to the assessment of climatic capability, this station lacks suitable potential for growing Rosa damascene.
Conclusion: In evaluating the ability of the habitat to plant a crop, not all criteria are equal. Some criteria play a key role. For this reason, factors are weighted in order to obtain a ranking of the value of decision criteria regarding suitable places for agriculture. The current research was conducted using TOPSIS and ANP methods and 6 effective atmospheric elements in the cultivation of Rosa damascene, standardization and formation of a ranking decision matrix based on these scores to determine and rank the Rosa damascene cultivation. These methods are more capable than other common methods. are doing the ranking more accurately. Finally, by interpolation (RBF) method, a map of the areas suitable for the cultivation of Rosa damascene was prepared. In the zoning map, there are very suitable areas for Mashgin Shahr station and unsuitable areas for cultivation at Parsabad station.
