Abstract: In order to research the climatic regionalization of ‘Red Fuji’ apple in Liaoning Province, precipitation and sunlight in grids were established by using the principles of geographical information system(GIS), based on climate data of 52 meteorological stations and geographic information in Liaoning Province, the climatic elements such as heat. According to the needs of ‘Red Fuji’ apple on climate condition, summarize suitable planting area in Liaoning Province was divided to four regions, which were most suitable zone, suitable zone, subsuitable zone and unsuitable zone, before giving planting suggestion, also analysis the characters of four regions. (1) The average temperature of January and the temperature index from April to October make great impact on the ‘Red Fuji’ apple growing, and therefore chose the two factors to divide climatic regionalization of ‘Red Fuji’ apple. (2) The development of ‘Red Fuji’ apple planting areas should stick on ‘-10℃ safe principle’. In south of Liaoning Province, Dalian can have rapid development, south of Yingkou City can have appropriate development. In the west of Liaoning Province, part of Huludao City, Chaoyang City and Jinzhou City can have appropriate development. In the middle of Liaoning Province, Panjin City can have appropriate development. In the east of Liaoning Province, seaside of south Dandong can have appropriate development.
