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。
In order to compare the difference of economic traits of flue-cured tobacco in different tobacco growing areas in Henan Province, the gray correlation cluster and decision analysis method were used to evaluate the yield, flue-cured tobacco and medium-flue-cured tobacco in 10 tobacco growing areas in Henan Province . The results showed that: According to the difference of economic traits in flue-cured tobacco in different areas, the ten tobacco growing areas can be divided into four groups: the first group mainly includes Sanmenxia, Luoyang and Jiyuan tobacco-growing areas; the second group mainly includes Xinyang tobacco-growing areas; the third group Mainly include Xuchang, Nanyang, Zhumadian, Pingdingshan and Luohe tobacco-growing areas; the fourth category mainly includes Shangqiu tobacco-growing areas. The comprehensive performance of economic traits of flue-cured tobacco in all kinds of groups showed as follows: Xuchang, Nanyang, Zhumadian, Pingdingshan and Luohe showed the best performance, the comprehensive evaluation value was 0.98, followed by Sanmenxia, Luoyang and Jiyuan tobacco, the comprehensive evaluation value was 0.93; Xinyang tobacco area is relatively low, the comprehensive evaluation value of 0.89; Shangqiu tobacco comprehensive evaluation of the lowest value, 0.85.
