Abstract

Considering the importance of minimum and maximum temperatures in the agricultural and gardeningsector, which each year causes significant losses in this sector. In order to avoid hazards in this section,detailed research has to be done and then filed a file with management and planning. The purpose of thepresent study and forecast the hazardous effects of thirty days extremes temperature on gardening andagronomy crops in the north bar of Iran. For this purpose, the first stage data were obtained for the wholestation temperature over a period of 30 years (1989-2018). Then, using ANFIS (Adaptive-Network-basedFuzzy Inference Systems) adaptive neural network model, the data were analyzed for prediction in the next 6years. Then, to measure the land suitability of Iran's northern strip for cultivating based on the predicted data,two models including Vikor (Vlse Kriterijumsk Optimizacija Kompromisno Resenje) and Topsis (Techniquefor Order Preference by Similarity to Ideal Solution) were used. Both the Topsis and Vikor multivariatedecision making models combined the minimum temperature of the stations well, but did not reflect well atthe maximum temperature in the worst-priority stations. According to the findings of the study, with respectto the friction extremes modeling, the maximum temperature showed the lowest defect compared to theminimum temperature. In Golestan province, the maximum temperature peaks and at least both are in weakincrement, but in Gilan province, the maximum temperature peaks and at least both the maximum andmaximum temperatures are higher. Mazandaran province showed maximum temperature and minimumtemperature in both incremental and minimum temperature conditions.
