Abstract: In order to study whether the climatic conditions in the Western Sichuan Plateau are suitable for large-scale strawberry planting in summer, daily meteorological data of 48 meteorological observation stations in the Western Sichuan Plateau, from 1986 to 2015, were used to establish temperature, water and comprehensive suitability evaluation model to analyze the suitability of strawberry growth in the Western Sichuan Plateau, with eco-fitness theory and fuzzy mathematics methods, and considering the biological characteristics of strawberries. After determining the suitable period for the growth of strawberries, the growth suitability of each growth periods was further analyzed, and the final suitability zoning of unseasonal strawberry was determined by comprehensive classification and scoring method. The results showed that, the period whose temperature condition was modestly suitable for strawberries growing in the Western Sichuan Plateau was concentrated from April to October. And, the water suitability and comprehensive suitability of the same period also reached the sub-optimal level or above, which could meet the basic needs of strawberry planting and ensure that strawberry fruit can be marketed in summer. In terms of zoning, the comprehensive suitable planting areas of unseasonal strawberry in the Western Sichuan Plateau were mainly concentrated in the central part of Liang’shan Prefecture; the secondary suitable area covered a wide area, covering the eastern and mid-western part of Liang’shan Prefecture, and the mid-southern parts of A’ba Prefecture and the eastern part of Gan’zi Prefecture, which further extended from the center to the west. Supplemented by agricultural techniques such as suitable sowing date and film mulching, the climatic conditions of most parts in the Western Sichuan Plateau were suitable for the cultivation of unseasonal strawberry.
