Abstract: Based on meteorological data and GIS,the correlative air temperature factors were calculated in Fujian Province by combining quadratic tendency curve model with inverse distance weighted interpolation,the dynamic clustering analysis was used to classify the restrained factor of air temperature for autumn peanut(Arachis hypogaea) planting.Results showed that the planting area for autumn peanut restrained by the air temperature took 42.22%,18.21%,14.56%,25.01% to the total farmland area for most serious,more serious, slight and none respectively.The Southeast of Fujian Province was the most suitable region for the autumn peanut planting,while the suitability for the autumn peanut planting ranged from the Southeast to the West,Middle,North and East of Fujian Province.

Key words: GIS, GIS, Air temperature, Autumn peanut planting, Suitability evaluation
