摘　　要：茶作为一种传统的经济作物,对人体健康具有良好效益,然而现有茶叶评价体系不足以反映其营养健康价值作用。基于此,该研究基于前期循证研究和川茶样品检测结果,在初步构建川茶营养健康评价初筛指标体系的基础上,采用德尔菲法两次邀请相关专家评价和筛选指标内容,并应用专家评价法以线下会评的方式对咨询结果进行适应性评估,最后使用层次分析法对指标进行权重赋值。结果表明,两轮德尔菲法的专家积极系数分别为88.23%和93.33%,专家权威系数(Cr)分别为(0.80±0.13)%和(0.87±0.11)%,专家意见协调系数分别为0.074(P>0.05)和0.256(P<0.01),最终建立了由6个一级指标、8个二级指标、6个三级指标和8个四级指标组成的川茶营养健康评价指标体系。该研究通过运用德尔菲法和层次分析法构建了川茶营养健康评价指标体系,为川茶及茶产业的种植、生产、销售等过程提供工具参考,可应用于川茶生产销售和茶叶营养健康价值的宣传,为茶叶评价方式的创新与完善提供一定的研究基础。As a traditional cash crop,tea has good benefits to human health,but the existing evaluation system of tea is insufficient to reflect its nutritional and health value.Based on the previous evidence-based research and the test results of Sichuan tea samples,the preliminary screening index system for the nutritional health evaluation of Sichuan tea was preliminarily constructed,and then related experts were invited to evaluate and screen the index content by using two rounds of Delphi expert consultation,and the expert evaluation method was used to evaluate the adaptability of the consultation results in the form of offline evaluation,and finally the analytic hierarchy process was used to assign weights to the indicators.The results showed that the expert positivity coefficients of the two rounds of Delphi method were 88.23%and 93.33%,the expert authority coefficients(Cr)were(0.80±0.13)%and(0.87±0.11)%,respectively,and the coordination coefficients of expert opinions were 0.074(P>0.05)and 0.256(P<0.01),respectively.A nutritional and health evaluation index system for Sichuan tea was ultimately established,consisting of 6 primary indicators,8 secondary indicators,6 tertiary indicators,and 8 quaternary indicators.In this study,the nutritional health evaluation index system of Sichuan tea was constructed by using the Delphi method and analytic hierarchy process,which provided a tool reference for the planting,production and sales of Sichuan tea and the tea industry,which could be applied to Sichuan tea sales and the promotion of the nutritional and health value of tea,and provide a certain research basis for the innovation and improvement of tea evaluation methods.
