摘要: 采用2003—2008 年全國烤煙中部煙葉厚度數(shù)據(jù),，通過Kriging 插值用Surfer 8.0 軟件繪制煙葉厚度等值線圖,，研究縣級區(qū)域尺度下煙葉厚度的空間分布特征。結(jié)果表明,，我國西北部,、東北部及黃淮地區(qū)為烤煙相對較厚的區(qū)域，西南地區(qū)次之,，長江流域,、皖南及東南地區(qū)為烤煙相對較薄的區(qū)域?？緹煙熑~厚度具有較為明顯的區(qū)域特性,。采用地統(tǒng)計學(xué)原理與等值線圖相結(jié)合的方法研究全國烤煙煙葉厚度的空間分布，可直觀展現(xiàn)全國烤煙煙葉厚度的區(qū)域性差異,。Abstract: In order to understand the diversity of the regional feature of flue cured tobacco leaf thickness, the leaf tobacco thickness data from 2003 to 2008 were used, the regional feature of leaf thickness of flue cured tobacco was studied by using county scale. The data were analyzed by the Kriging interpolation method in the SURFER software. The results showed that the leaf thickness of flue-cured tobacco was relatively thick in northwestern and northeastern China, and Huanghe and Huaihe valley, but the thickness was relatively thin in Yangtze valley, southern Anhui and southeastern China. The leaf thickness varied with region. The regional feature distribution of leaf thickness of flue cured tobacco could be displayed visually by use of geostatistical analysis and contour map approaches.
