Abstract

Selenium (Se) is a vital nutrient for human health and closely associated with various bodily functions. Human intake of Se is often increased through the diet, and the Se level in crops is not solely dictated by soil Se levels. For example, it also depends on the interactions between plants and soil elements. This study explored the factors influencing the Se bioaccumulation coefficient in lilies in karst areas, based on 1:50,000 land-quality geochemical survey data. Utilizing a random forest, two indicators (Se and nitrogen) were selected from 49 soil indicators to predict the Se content in lilies, thereby providing a more flexible and scientific approach to planning Se-rich agricultural products. The results show that the random forest model predicts Se content in lilies more accurately and precisely than traditional multiple linear regression. These findings provide theoretical support for the rational layout of Se-rich agricultural production areas and promotes the high-quality, sustainable development of regional specialty agriculture.

利用随机森林模型探索富硒百合栽培的影响指标。

硒（Se）是一种对人体健康至关重要的营养物质，与人体各种机能密切相关。人体硒的摄入量通常通过饮食增加，而作物中的硒水平并不完全取决于土壤中的硒水平。例如，它还取决于植物和土壤元素之间的相互作用。基于1:5万土地质量地球化学调查资料，探讨喀斯特地区百合花硒生物积累系数的影响因素。利用随机森林，从49个土壤指标中选择2个指标（Se和nitrogen）来预测百合花的Se含量，从而为富硒农产品的规划提供更加灵活和科学的方法。结果表明，与传统的多元线性回归模型相比，随机森林模型对百合花硒含量的预测精度更高。研究结果为合理布局富硒农业产区，促进区域特色农业的高质量、可持续发展提供了理论支持。

期刊介绍： Environmental Geochemistry and Health publishes original research papers and review papers across the broad field of environmental geochemistry. Environmental geochemistry and health establishes and explains links between the natural or disturbed chemical composition of the earth’s surface and the health of plants, animals and people. Beneficial elements regulate or promote enzymatic and hormonal activity whereas other elements may be toxic. Bedrock geochemistry controls the composition of soil and hence that of water and vegetation. Environmental issues, such as pollution, arising from the extraction and use of mineral resources, are discussed. The effects of contaminants introduced into the earth’s geochemical systems are examined. Geochemical surveys of soil, water and plants show how major and trace elements are distributed geographically. Associated epidemiological studies reveal the possibility of causal links between the natural or disturbed geochemical environment and disease. Experimental research illuminates the nature or consequences of natural or disturbed geochemical processes. The journal particularly welcomes novel research linking environmental geochemistry and health issues on such topics as: heavy metals (including mercury), persistent organic pollutants (POPs), and mixed chemicals emitted through human activities, such as uncontrolled recycling of electronic-waste; waste recycling; surface-atmospheric interaction processes (natural and anthropogenic emissions, vertical transport, deposition, and physical-chemical interaction) of gases and aerosols; phytoremediation/restoration of contaminated sites; food contamination and safety; environmental effects of medicines; effects and toxicity of mixed pollutants; speciation of heavy metals/metalloids; effects of mining; disturbed geochemistry from human behavior, natural or man-made hazards; particle and nanoparticle toxicology; risk and the vulnerability of populations, etc.
