In order to improve the brand effect and market competitiveness of Putian Wendan pomelo, the climatic quality evaluation targets are built by analyzing the key meteorological factors and major meteorological disasters affecting the fruit quality based on the observational data of regional automatic stations over the years, and quality test data in pomelo’s planting area. Using the expert scoring method and analytic hierarchy process, the weights of climatic suitability factors and hazard inducing factors are determined. The climatic quality evaluation model is established, and the climatic quality index is calculated and quantitatively graded to carry out the climatic quality assessment. The results show that simulative results of the climatic quality evaluation model based on climatic suitability indicators and meteorological disaster ones can quantitatively reflect the impact of meteorological conditions on the quality. Compared with the actual fruit quality, fruit quality in typically historical years and fruit quality in different altitudes, the climatic quality evaluation results are highly consistent with fruit quality and can reflect the actual quality fairly. The evaluation model and results are objective, which can provide technical support for the climatic quality authentication of Putian Wendan pomelo.
