摘　　要：对作物品种区试综合评价指标体系的建立进行了系统论述,分析了"正向"、"反向"、"有界"、"适性"评价目标类型的确定和"全面、重点、简便"评价指标数量的选取方法,运用多目标决策的效用函数法对评价指标数据进行标准化处理、运用熵权系数法确定权重,提出了基于熵权的多目标关联分析法。用该方法对作物品种区试进行综合评价,其结果更加全面客观、真实可靠。This paper demonstrated the foundation of the integrated evaluation index system in crop regional test in detail, and analyzed the confirmation of the evaluation target type such as ＂positive direction＂, ＂reverse direction＂, ＂limitation＂, ＂suitability＂ and the selection method of the evaluation index number. In this paper, a method of multi-objective relational analysis based on entropy weight is presented by normalizing the data of the evaluation index with the utility function of multi-objective decision-making and confirming the weight with entropy coefficient. To apply the method in crop regional test made the results of comprehensive evaluation more impersonal and reliable.
