摘要
在灰色综合隶属度评价方法基础上,按照离差最大化原理,提出了一种品种区域试验的新的确定权重的方法.应用这种方法,对2002-2003年度国家黄淮南片小麦冬水组区域试验进行了分析.结果表明,这种分析方法克服了通常专家调查法和层次分析法主观随意性强的缺点,因而其分析结果更加客观、可靠.大面积生产实践也表明该方法具有一定可行性和有效性.
Based on the evaluation method of grey comprehensive subordination degree, a new method of determining the weight for the variety regional test was proposed in accordance with the principle of maximum deviation in this paper. Using the method, the analysis was carried on for the regional test of winter wheat variety in the south of Huanhuai River valley in China in 2002--2003. The results show that the analysis method overcomes the weakness of subjectivity from the methods of expert consultant and analytical hierarch process, its analysis results will be more objective and reliahle. The production practices in Large areas show that the method has a definite feasihility and availability.
