| 摘 要： | 分析了鱼台区域表层土壤和2个典型剖面中砷的分布特征,讨论了地质条件、气候环境、地形地貌、农作物类型和农田灌溉用水等自然和人为因素对土壤砷分布的影响。结果表明,土壤中砷的主要来源是母岩,其分布主要受地质构造的影响;气候环境和地形地貌对砷的风化和土壤砷迁移具有重要影响;高砷农田灌溉和主要以水田为主加剧了土壤砷污染;高砷农药和化肥的施用造成了高砷区的点状分布。

| Abstract: | The distribution of arsenic in surface soil and 2 typical sections of Yutai region was analyzed, and the effects of natural and artificial factors such as geological conditions, climatic environment, landform and physiognomy, crop types and farmland irrigation water on arsenic distribution in soil were discussed. The results showed that the arsenic in soil mainly came from parent rocks and its distribution was affected by geological structure. Climatic environment and landform and physiognomy had important effects on weathering and migration of arsenic in soil. Arsenic pollution in soil was aggravated by farmland irrigation with high arsenic water and the main land-use types of paddy fields. The point shape distribution of high arsenic region was caused by application of high arsenic pesticide and fertilizer. |
