| 摘 要： | 以中国烤烟(Nicotiana tabacum)主产省份2005年B2F(上部二级桔黄色烤烟)、C3F(中部三级桔黄色烤烟)和X2F(下部二级桔黄色烤烟)3个等级烤烟为研究对象,利用地统计学与GIS技术结合的方法研究了中国烤烟主产省份烤烟水溶性总糖、还原糖含量和糖碱比的空间分布特征。结果表明:各等级烤烟水溶性总糖、还原糖含量和糖碱比空间相关性表现为近似相关,东西方向上,均呈现由西向东先降低后升高的趋势,南北方向上,水溶性总糖含量、还原糖含量趋势不明显,糖碱比各等级趋势各异。

| Abstract: | Taking three grades(B2F,C3F and X2F)flue-cure tobacco(Nicotiana tabacum)leaves from main production provinces in China as study objects,this paper studied the spatial variability of their water-soluble sugar and reducing sugar contents by the methods of geostatistics and GIS technique.The results indicated that the water-soluble sugar,reducing sugar,and sugar-nicotine ratio in these three grades flue-cure tobacco leaves had a moderate spatial correlation,with an increase after an initial decrease of these parameters from west to east,and no evident variation trend for water-soluble sugar and reducing sugar but differed in sugar-nicotine ratio from south to north. |

| Keywords: | flue-cured tobacco water-soluble sugar reducing sugar sugar/nicotine ratio spatial variability geostatistics |
