熵值赋权的DTOPSIS法在烟草品种试验中的应用

摘要

In order to properly identify the best tested tobacco varieties in Tobacco Regional Trial,DTOPSIS method based on entropy weight determining the weight was employed for the comprehensive evaluation of eight tobacco varieties on the output,average price,superior tobacco ratio,the number of leaves,plant height,total alkaloids,total sugar,potassium content in National Flue-Cured Tobacco Variety Trial southwest regional test in 2010.The results showed that among the tested tobacco varieties,YN105 and QL-3 performed the best,YN110 and Qianyan7 performed better,Y892,Qianyan1,CF221 performed the worst.Moreover,the evaluation results were in accordance with actual performance,so using the DTOPSIS method based on entropy weight determining the weight to evaluate tobacco variety trial was feasible.%为了更准确地评价烟草品种区域试验中参试品种的优劣,应用熵值赋权的DTOPSIS评价法,根据8个区域试验品种在2010年全国烤烟品种区域试验西南区的产量、均价、上等烟比例、叶片数、株高、总植物碱、总糖、钾含量等多个指标对参试品种进行综合评价.结果表明,参试品种中YN105、QL-3表现最好,YNll0、黔烟7号次之,Y892、黔烟1号、CF221表现劣于对照K326.结果与品种实际表现一致,表明运用熵值赋权的DTOPSIS法对烤烟品种试验进行综合评价是可行的.
