在云南昭通10个植烟生态区进行田间试验，以探讨土壤-气候、烟草品种及其互作对烟叶重金属含量的影响。结果表明，昭通烟区烟叶铜、汞和砷含量较低，镍含量较高，而锌、铅和镉与其他烟区烟叶的含量相当。土壤-气候、烟草品种及其互作和烟叶等级对昭通烟叶重金属含量的影响程度不同，它们对烟叶中7种化学成分含量总变异的贡献率分别为57.3%、3.4%、22.3%、17.0%，土壤-气候对烟叶重金属含量的影响最大，品种的影响最小。在土壤-气候因素中，土壤对烟叶重金属含量的影响具有主导性和普遍性，气象因子的作用则是次要的。

Field experiments were carried out at ten tobacco-planting eco-regions in Zhaotong, Yunnan Province, to investigate the contents of heavy metals in tobacco leaves and their association with soil and climate conditions. The tobacco leaves in Zhaotong were characterized with lower contents of copper, mercury and arsenic and higher content of nickel, while the contents of zinc, lead and cadmium were similar to other tobacco-planting regions. The influencing degree of soil-climate and other factors on heavy metal contents of tobacco leaves varied. The relative contribution of soil-climate, tobacco variety and their interaction and leaf grade to total variation of the seven chemical components in tobacco leaves was 57.3%, 3.4%, 22.3%and 17.0%, respectively. This indicated that soil-climate conditions had the strongest effect on the heavy metal contents of tobacco leaves while the effect of variety was negligible. As to the soil-climate conditions, soil played a predominant role in controlling heavy metal contents of tobacco leaves while climate was secondary.
