%X 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.
