| 中文摘要: |
| 研究表明微量元素硒能很好改善人体的免疫机能，为人体所需的必要微量元素。本文结合贵州省天柱县 1∶50000耕地质量地球化学调查成果，总结不同土壤类型、成土母质、土地利用类型及土壤中硒含量分布 特征，并结合地质背景分析其影响因素，对土壤硒成因来源进行研究。研究结果表明，天柱县富硒耕地的 分布主要受地质背景影响最大，不同的土地利用类型、土壤酸碱度对硒元素富集有一定的关系。 |
| 英文摘要: |
| Research showed that the trace element selenium can greatly improve the body′s immune functionand was an essential trace element needed by the human body. This study integrated the results of a 1∶50，000-scale geochemical survey of cultivated land quality in Tianzhou County，Guizhou Province. It summarized the distribution characteristics of selenium content in soils of different types，parent materials，and land use categories. By analyzing influencing factors within the geological context，the study investigated the origin andsources of selenium in these soils. The results showed that the distribution of selenium-enriched farmland in Tianzhou County was primarily influenced by geological background，while different land use types and soil pH levels also exert a certain degree of influence on selenium accumulation. |
