基于层次分析法的模糊综合评判在栀子内在品质区划中的应用

为了更加高效合理地区划栀子(Gardenia jasminoides Ellis)品质产区,建立一种定性与定量、主观与客观相结合的综合评价方法,采用层次分析法和模糊综合评判法,确定区划指标权重,设计模糊隶属度函数,构建综合评判模型,合理区划全国栀子品质产区。结果显示,江西省湖口县、江西省进贤县、广西壮族自治区扶绥县3个栀子产区综合指标值均大于0.5,为最佳品质区;浙江省景宁县、福建省福鼎市、浙江省永嘉县3个产区指标值小于0.2,为品质差区。该评价结果大致与各地栀子品质实际情况相符合,说明该方法实用可行,是一种科学合理的综合评判方法。

Application of Fuzzy Comprehensive Evaluation Based on AHP for Internal Quality Division of Gardenia jasminoides

To divide the quality production areas of Gardenia jasminoides Ellis efficiently and resonablely, and to establish a comprehensive evaluation method of the combination of qualitative and quantitative, subjective and objective, the analytic hi-erarchy process and fuzzy comprehensive evaluation method were applied to determine the zoning index weight, design the fuzzy membership function, and construct a comprehensive evaluation model to zone the national quality production areas of G. jasminoides resonablely. Results showed that the comprehensive index of G. jasminoides in Hukou county and Jinxian county of Jiangxi province and Fusui county of Guangxi Zhuang Autonomous Region was over 0.5, which were the best qual-ity areas. Oppositely, the comprehensive index of G. jasminoides in Jingning county and Yongjia county of Zhejiang province, Fuding city of Fujian province was under 0.2, which were the poor quality areas. Evaluation results was basically in accord with the actual situation, indicating this method is practical and feasible, thus is a scientific and reasonable comprehensive evaluation method.
