Abstract: In order to evaluate the suitability of the eco-climate resources for the growth and development of blueberry, the evaluation index system of eco-climate suitability of blueberry was established based on the scientific, systematic, practical and dynamic principles, 12 indexes from 3 aspects (the ecological environment, the climate condition in growth period and field management level) were selected. The membership functions of the soil, temperature and other factors on the eco-climate suitability of blueberry were established by the fuzzy mathematics theory, meanwhile, a two-level hierarchy evaluation model was constructed combined with the expert scoring method of the weight of each factor. The eco-climate suitability degree of blueberry in the specific cultivation land and time period could be determined by the evaluation model. This study filled up the blank of the fuzzy evaluation of the eco-climate suitability of blueberry in China, provided a scientific basis for introduction, garden establishment, yield and quality prediction, and meteorological disaster assessment.
