The relationship between the geographic environment and human health has been a long-standing focus of scientific inquiry. Sn as an essential trace element for the human body, play vital roles in individual health and may influence longevity. However, the extent to which the statistical characteristics of population longevity are associated with elemental geochemical background values at a regional scale remains an important question. Based on the geochemical survey data of Yunnan Province and Chinese census data, the article utilizes Arcgis spatial analysis and mathematical statistics to explore the relationship between ω(Sn) and regional longevity level. The results of the study show that: (1) There is a close correlation between ω(Sn) and regional longevity levels. Within Yunnan Province, regions with high ω(Sn) have higher levels of longevity index and Ultra-octogenarian Index. (2) Spearman's correlation coefficient shows that ω(Sn) is significantly positively (P < 0.01) correlated with both the longevity index and the Ultra-octogenarian Index; Linear regression further reveals that ω(Sn) always has a significant positive influence on the longevity index. For the Ultra-octogenarian Index, although the strength of the influence of ω(Sn) is not as significant as that of the longevity index, its influence on the healthy longevity of the population cannot be ignored. At the county scale in Yunnan Province, there is a significant positive correlation between ω(Sn) and longevity index, which may be related to the exposure of Sn in the natural environmental background into the human body and thus affecting the incidence of cancer, but the biogeochemical cycling mechanism of its association with longevity still needs to be further investigated.
地理环境与人类健康之间的关系一直是科学探究的长期焦点。锡作为人体必需的微量元素，在个体健康中发挥着至关重要的作用，并可能影响寿命。然而，在区域尺度上，人口寿命的统计特征与元素地球化学背景值之间的关联程度仍是一个重要问题。基于云南省的地球化学调查数据和中国人口普查数据，本文利用ArcGIS空间分析和数理统计方法，探讨ω（锡）与区域长寿水平之间的关系。研究结果表明：（1）ω（锡）与区域长寿水平密切相关。在云南省内，ω（锡）含量高的地区具有较高的长寿指数和超高龄老人指数。（2）斯皮尔曼相关系数表明，ω（锡）与长寿指数和超高龄老人指数均呈显著正相关（P < 0.01）；线性回归进一步表明，ω（锡）对长寿指数始终具有显著的正向影响。对于超高龄老人指数，尽管ω（锡）的影响强度不如长寿指数显著，但其对人群健康长寿的影响不容忽视。在云南省县级尺度上，ω（锡）与长寿指数之间存在显著正相关，这可能与自然环境背景中的锡暴露进入人体进而影响癌症发病率有关，但其与长寿关联的生物地球化学循环机制仍需进一步研究。
