摘　　要：对红云红河集团云南省卷烟原料基地的生态因子进行主成分分析和构建数学模型,筛选不同档次原料基地的关键生态因子。结果表明,红云红河集团省内原料基地烟叶符合作高档原料的占32.0%;符合作中档原料的占58.7%;符合作中低档原料的占9.3%。海拔、土壤质地及大田期降雨量是影响各档次原料形成的主要生态因子,对高档、中档及中低档原料影响的平均权重分别为22.80%、19.27%、19.13%,平均权重之和达61.20%,是集团划分不同档次原料产地生态条件的主要区划指标。The principal component analyses and mathematical model construction of ecological factors in material base of Hongyunhonghe To-bacco Group in Yunnan Province was conducted. The key ecological factors were selected in different tobacco-planting bases. The result showed high- grade material was 32.00%, middle-grade materials was 58.7%, middle-low grade materials was 9.3%. The key ecological factors were altitude, soil texture and field period rainfall. The altitude of average influence was 22.80% for different grade material. The average influence of soil texture was 19.27% for different grade material. The average influence of field period rainfall was 19.13% for different grade material. The total of average influence was 61.20%. The ecological factors were used to divide finsh region partition in Yunnan Province in material bases of Hongyunhonghe Tobacco Group by altitude, soil texture and field period rainfall for index.
