| 摘 要： | 应用同位素（125I）示踪技术,在模拟条件下,通过淋溶试验,研究土壤碘的环境地球化学迁移特征及其影响因素.研究表明：土壤碘（125I）的迁移、挥发和被淋溶的数量与土壤质地有关,淋溶液的酸碱度对土壤碘的流失产生明显的影响.这些研究结果为提高作物吸收碘的效率,进而开辟生产化防治IDD的新途径提供重要的科学依据.

| Abstract: | The environmental and geochemical migration of iodine in soil and its influencing factors were studied by the isotope tracer （125 I） under simulated condition.The quantitative model of iodine in soil transfer is charted.The results show that the quantities of transferred,volatilized,leached 125I in soil have relations with the texture of soils and the pH of leachate have an important influence on iodine being washed away from soil.These results provide important scientific basis for preserving iodine in soil and enhancing efficiency of plants absorbing iodine. |
