摘要

The mathematical model of analytic hierarchy process (AHP)—fuzzy comprehensive evaluation (FCE) was applied to comprehensively evaluate the germplasm resources of Sterculia nobilis Smith, and the scientific nature and reliability of the mathematical model was verified by calculating index weights and comprehensive evaluation scores. In this paper, 11 indicators were selected to construct a comprehensive evaluation system from four dimensions of yields, resistances, contents of main inclusions in seeds and tree shapes. AHP method was applied to calculate the index weight of each dimension, after passing the consistency test, FCE method was applied to comprehensively evaluate germplasm resources of S. nobilis Smith. The index weights of the yields, resistances, contents of major inclusions in seeds and tree shapes were 0.5518, 0.2554, 0.1279 and 0.0649, respectively. The yield had the greatest influence on the comprehensive evaluation of germplasm resources of S. nobilis Smith, which was in line with the actual production demand of S. nobilis Smith as a food crop. However, resistances and contents of major inclusions in seeds had limited influence on it, while tree shapes had the least influence on it. After fuzzy comprehensive evaluation, the final evaluation score was 88.00, the corresponding evaluation score was between 4 and 5, and the evaluation results ranged from slight good to good, which indicated that the evaluation weights corresponding to the four dimensions were more scientific and reasonable. In this study, the mathematical model of AHP-FCE was used to establish and evaluate the comprehensive evaluation system of the germplasm resources of S. nobilis Smith. According to the values of index weights and the evaluation results, it showed that the mathematical model was scientific and reliable, and it could provide a new reference method for the comprehensive evaluation of germplasm resources of other fruits.
