Abstract: Based on daily meteorological data of 10 national meteorological stations in mountainous area of central and southern Ningxia from 1981 to 2018, the calculation model of comprehensive suitability for potato in mountainous area of central and southern Ningxia was established by integrating the indexes such as temperature, sunshine and water suitability, and characteristics of temporal and spatial variation of temperature suitability （PT）, sunshine suitability （PS）, water suitability （PW）, comprehensive suitability （P） were analyzed emphatically. The results show that the thermal and sunshine resources were suitable in mountainous area of central and southern Ningxia, which could meet the needs of potato’s growth in different growth stages. Among them, water was the main limiting factor affecting the growth stages of potato, and the annual fluctuation of water suitability was the largest. The variation coefficient of the comprehensive suitability from the branching stage to the flowering stage was the largest, which was the most unstable period when the climatic conditions affected the growth and development of potato. From the perspective of spatial variation, the comprehensive suitability of the whole growth period of potato showed an increasing trend from northeast to southwest, and the most suitable areas were in Xiji county, most areas of Haiyuan county and Yuanzhou district, western of Pengyang county, the most areas of Longde county and Jingyuan county except the higher elevation ridge of the Liupan Mountain, which had the unique climatic advantages suitable for potato production.
