Abstract: In order to explore the suitable climatic conditions for oil peony planting in Yibin and layout the planting area rationally, the climatic data of 20 meteorological stations in Yibin and surrounding areas were used. The annual average temperature, days of daily average temperature less than 10°C, flowering temperature and pod formation temperature were selected as climatic suitable zoning indexes. Based on 1:250000 geographic information data, the multiple regression equation was adopted to establish the relationship model between climatic factors and geographical factors. The suitable area, sub-suitable area and unsuitable area of oil peony planting were drawn by GIS. The results showed that the suitable areas for planting oil peony in Yibin City were mainly distributed in the hilly and Pingba areas where the annual average temperature was greater than 16°C, and the unsuitable areas were mainly distributed in the altitude areas above 1200m such as Pingshan County, Gong County, Xingwen County and Junlian County.
