河西东部枸杞综合品质评价指标的建构

研究河西东部枸杞品质评定指标,可为区域产业发展、品种优选以及品牌营销提供理论支撑。笔者以2016年试验数据为基础,将生长量指标与理化指标作为评价依据,采用熵权法和主成分分析对16个批次红枸杞进行各评价指标的权重赋值,并借助动态赋值对2种评价权重进行综合赋值,然后利用评价模型有效实现了枸杞的品质评定,结果显示丰乐基地品质最为突出,评定结果与实际相符。本研究为河西东部红枸杞质量评定提供了基本方法。

Quality of Lycium barbarum in East Hexi Corridor Region: Comprehensive Assessing Index Construction

The quality evaluation of Lycium barbarum in the east of Hexi corridor can provide theoretical support for the development of regional industry, selection of varieties and brand marketing. Based on the test data of 2016, the growth index and physicochemical indexes as the evaluation basis, using entropy method and principal component analysis method, analysis of evaluation index weight, and the dynamic assignment conducted a comprehensive assignment to the above two kinds of weights, established the evaluation model and to evaluate the regional quality of Lycium barbarum. The results showed that the best quality of Fengle, the evaluation result was consistented with the actual sample. This study provides a basic method for the quality evaluation of Lycium barbarum in the east of Hexi corridor.
