河南烟区烤烟经济性状的灰关联聚类分析评价

为了比较河南省不同烟草种植区烤烟经济性状的差异,运用灰色关联聚类和决策分析方法分别对河南省10个烟草种植区的烤烟产量、上等烟和中等烟比例3个指标进行了综合评价。结果表明:根据不同烟区烤烟经济性状的差异,10个烟草种植区可分为4个类群:第Ⅰ类群主要包括三门峡、洛阳和济源烟区;第Ⅱ类群主要包括信阳烟区;第Ⅲ类群主要包括许昌、南阳、驻马店、平顶山和漯河烟区;第Ⅳ类主要包括商丘烟区。各类群烟区烤烟经济性状的综合表现为:许昌、南阳、驻马店、平顶山和漯河烟区表现最优,综合评价值为0.98;三门峡、洛阳和济源烟区次之,综合评价值为0.93;信阳烟区相对较低,综合评价值为0.89;商丘烟区综合评价值最低,为0.85。

Grey Correlation Clustering Analysis and Evaluation of Economic Traits of Flue Cured Tobacco Produced in He'nan Province

In order to compare the differences in economic characters of flue-cured tobacco between different growing areas in Henan Province, this paper used grey correlation clustering and decision methods to conduct comprehensive evaluation on following 3 targets: tobacco yield, first class, and middle class tobacco leaf proportion in 10 tobacco planting areas of Henan Province. The results indicated that according to the different economic traits of tobacco planted in different areas, the 10 tobacco planting areas could be divided into 4 categories: the first group included Sanmenxia, Luoyang and Jiyuan; the second group included Xinyang; and the third group included Xuchang, Nanyang, Zhumadian, Pingdingshan, Luohe; and the fourth group included Shangqiu tobacco planting areas. The comprehensive performance of tobacco economic traits of various flue-cured groups showed that the performance of Xuchang, Nanyang, Zhumadian, Pingdingshan, Luohe tobacco planting areas was the best, their comprehensive evaluation value was 0.98; followed by Sanmenxia, Luoyang and Jiyuan, their comprehensive evaluation value was 0.93; the performance of Xinyang tobacco planting areas was relatively low and their comprehensive evaluation value was 0.89; Shangqiu tobacco planting areas was the lowest and their comprehensive evaluation value was 0.85.
