提对冀中南平原土壤碘的地球化学分布特征及其控制因素的研究表明，冀中南平原滨海盐土和沼泽土中碘含量最高，白洋淀湖泊沼泽相和沧州东部的滨海平原深层土壤碘含量较高，而太行山中段滹沱河冲积扇平原、漳河冲积扇平原深层土壤碘含量较低，显示沉积环境是控制土壤碘区域分布的重要因素。研究认为土壤碘的分布特征受自然因素和人为因素的影响，以自然因素为主，表层土壤碘受到较大的人为因素影响。

With central south Hebei plain as the study area, to study iodine geochemistry of soil in detail and explored its controlling factors, the authors studied the distribution of iodine based on the analysis of iodine content in different soile stypes and different sedimentary environment.The results show that the most content of iodine element in different soile stypes of central south Hebei plain is coastal solonchak and bog soil.The sedimentary environment with more iodine element content in the deep soil is the lakes and swamps phase of Baiyangdian and coastal plain of Cangzhou,the sedimentary environment with lower iodine element content is alluvial fan plain of Hutuo River in the middle of Taihang Mountain and Zang River. The distribution of iodine element in soil is significantly affected by physical factors and human factors in the area,with the physical factors play the leading role, on this basis, human factors have a greater impact on the iodine element content of topsoil.
