wheat is the most important crop of the country and has an important role in providing nutrition to the people,if it is possible to identify suitable areas for wheat cultivation with the climatic requirements of this product that the climate has created in the environment. More performance per unit area can be achieved. In this study, using 20-year climatic data (1377-1396),based on which the average of climatic variables 10 months of the year(October -July)in It is considered and using the parameters used in this research(average monthly minimum and maximum temperature,average monthly temperature,average total 10 months temperature, average minimum and maximum humidity,average monthly humidity, average total 10 months humidity,average monthly rainfall The average total rainfall of 10 months,number of hours of sunshine(GDD), suitable wheat cultivation sites in Lorestan province have been investigated. After analysis and data for each station by cluster analysis of suitable cultivation areas in Lorestan province were identified and classified and for each variable a map was drawn.Then by drawing a tree diagram for the data and by cutting the clustering tree,through the Euclidean distance,in relation to the favorable climatic needs for wheat cultivation,four classifications were drawn for Lorestan province.The results showed that suitable areas for wheat cultivation in terms of all climatic elements are in the second,third and fourth classes (Boroujerd,Azna,Aligudarz,Droud,Kuhdasht and parts of Khorramabad, Aleshtar, Noorabad) and weak wheat cultivation classes from in terms of rainfall and humidity,they are located on the first floor of the first floor (Poldakhtar) and the southern parts of Khorramabad.
