为明确大理州植烟土壤有效锌的分布特征、合理调控土壤锌平衡，采集并分析了1131个土壤样品。结果表明：①大理州植烟土壤有效锌含量平均为3.11 mg/kg，变幅为0.07～72.92 mg/kg，变异系数146.95%，只有少部分烟区土壤缺锌，具体分布在云龙、永平、漾濞、祥云、巍山和宾川6个县；②不同类型植烟土壤有效锌含量依次为紫色土>水稻土>红壤>新积土>黄壤；③不同海拔高度植烟土壤有效锌分布依次为高海拔(＞2100 m)>低海拔(＜1700 m)>中海拔(1700～2100 m)；④pH在5.0～7.0范围内的土壤有效锌含量较高，比例占总样品数的70.55%；⑤土壤有效锌含量随土壤有机质含量的增加而提高。

In order to better know the distribution of available zinc in Dali tobacco growing soil and control zinc balance in soil reasonably, 1 131 soil samples were collected and analyzed. The results showed that: 1) The average content of available zinc was of 3.11 mg/kg ranged from 0.07 to 72.92 mg/kg with a variation coefficient of 146.95%. Only Yunlong, Yongping, Yangbi, Xiangyun, Weishan and Binchuan counties were zinc-deficient. 2) Soil types in the order of available zinc content were purple soil > paddy soil > red soil > alluvial soil > yellow soil. 3) By altitudes, the order of available zinc content were high altitude (>2 100 m) > low altitude (<1 700 m) > medium altitude (1 700-2 100 m). 4) Soil with pH of 5.0-7.0 was of higher available zinc content, which accounted for 70.55% of all samples. 5) The content of available zinc increased with the increase of organic matter content in soil.
