基于熵值赋权的DTOPSIS法对不同玉米品种综合评价研究
为探讨玉米品种综合评价的新方法，筛选出综合性状优良的玉米品种，本研究利用基于熵值赋权的DTOPSIS法对黑龙江省八五二农场新推广的36个玉米品种进行了综合分析及评价。结果表明：运用DTOPSIS法对玉米品种进行评价，能将各个性状指标无量纲化并综合分析，避免了评价指标之间的不公度性和矛盾性的问题；熵值赋权法客观评价了各指标在该评价体系中的重要程度，避免了主观因素对评价结果的影响，使评价更加科学；供试品种中，值排名前5的品种分别是兴垦9号、德美亚3号、东农281、东农265及哈育189，其综合性状表现优良。
英文摘要:
In order to explore a new method for comprehensive evaluation of maize varieties and select maize varieties with excellent comprehensive characters, this study used the entropy weighted DTOPSIS method to conduct comprehensive analysis and evaluation of 36 newly promoted maize varieties in 852 farm of heilongjiang province. The results showed that the application of DTOPSIS method in the evaluation of maize varieties could make every character index dimensionless and analyze comprehensively, and avoid the unfairness and contradiction among evaluation indexes;The entropy weighting method objectively evaluates the importance of each index in the evaluation system, avoids the influence of subjective factors on the evaluation results, and makes the evaluation more scientific;Among the tested varieties, the top 5 values were xingken 9, demeiya 3, dongnong 281, dongnong 265, and hayu 189, respectively.
