摘要: 为提高对区域试验参试品种评价的科学性和合理性,采用模糊数学和信息熵理论,提出了作物品种模糊熵权综合评价方法。该法利用作物品种区试的综合性状指标,建立相应的评价指标矩阵,然后借助信息论中的熵权理论,利用各评价指标的变异程度计算权重,实现品种的综合评价。最后结合棉花区试资料,介绍了该法的应用,验证了其可行性和有效性。

Abstract: In order to improve the scientific and rationality of the evaluation method to the varieties in regional test, with the application of fuzzy theory and information entropy theory, a new comprehensive assesement evaluation method of crop cultivars was proposed. Firstly, the corresponding comprehensive assessment index matrix of crop cultivars was established according to fuzzy and comprehensive assessment index. Secondly, the arithmetic about entropy weight was realized according to the difference of index, and the crop cultivars were evaluated by entropy. Finally, with the regional test of cotton cultivars, the new assessment method was recommended, and feasibility and validity of the method were proved.
