Abstract:  Planting blueberries not only can obtain high economical benefits, but also can improve the planting system of fruit in Fujian to promote the development of modern agriculture and increase the income of fruit farmers. Currently, there is no climatic suitability zoning of blueberry in Fujian. Consequently, it is necessary to study climate suitability zoning of blueberry in Fujian. Authors take advantage of the 66 national meteorological station data from 1960 to 2018 and the geographic information data in Fujian to analyze climate suitability zoning of blueberry, and other literature review data are used for reference. According to the ecological conditions required for blueberry based on the actual situation，climatic indices of the accumulated cold temperature in dormant period, the low temperature index during flowering period, and precipitation during fruit development stage are selected as the indicators of climate suitability zoning for blueberry growing in the study area. The weight of each index factor is calculated by the mathematical statistics methods such as normalization method and weight-coefficient methods. The climate suitability zoning of blueberry planting is obtained by the weight superposition analysis. The map of the suitability zoning of blueberry planting is drawn on the GIS platform with the aid of spatial analysis techniques. The results show that the coastal areas in the south of Fuqing is not suitable for blueberry planting since the accumulated cold temperature is inadequate; Nanping, Sanming, and the middle with high-altitude area of Longyan are sub-suitable area for blueberry planting, since the accumulated cold temperature could meet blueberries’ deed for dormancy, while requiring effective cold and frost protection measures from the high frequency of the low temperature freezing damage in spring. The landlocked of Ningde, Fuzhou, Putian and the low-altitude areas of Nanping, Sanming, Longyan are the most climate suitable planting areas for the long-term accumulation of cold temperatures, low frequency of freezing damage in spring, and suitable precipitation in rainy seasons.
