Abstract: The paper aims to develop the climate suitability evaluation of peanut, clarify the climate difference pattern of peanut plantation and climate suitability distribution areas of peanut in China. Based on the production characteristics of peanut and the suitability of climatic factors, we selected 6 climatic evaluation indicators including temperature, precipitation and sunshine characteristics, and evaluated climate suitability of peanut by using GIS and fuzzy mathematics, and the evaluation results were divided into the most appropriate, suitable, sub-appropriate and unsuitable 4 levels; and obtained the cultivated land rank of peanut climate suitability grades in China by using 1:1 million cultivated land vector data mask analysis. The results showed that: the cultivated land rank of peanut climate suitability grades in China was: the suitable area>the most suitable area>sub-suitable area>unsuitable area; the most suitable regions for peanut planting were mainly distributed in north China and Sichuan basin accounted for 40.78%; besides, the suitable regions for peanut planting were mainly distributed in eastern China and northeast China. This paper gets the climatic dominant areas of peanut planting in China and put forward the key development direction, which can provide basis for macro decision-making, such as the structure adjustment of planting and the layout and optimization of peanut industry
