1、赣南（苏区）高稀土地质环境中白莲体内稀土元素迁聚特征及影响研究中文摘要(限400字)：本课题通过对样地岩石-土壤-白莲植物体的立体解剖，研究稀土高背景区与稀土低背景区不同稀土含量对白莲品质的影响，从总量上把握土壤环境稀土浓度与白莲品质的关系；研究高稀土地质土壤环境中不同稀土组合对白莲品质的影响，探查不同稀土组合与不同白莲品质响应关系；研究稀土元素从岩石-土壤各层位的演化、从土壤-白莲植物体各器官的迁移、累积和分馏分异动态变化规律。通过研究：探明地质土壤环境中稀土含量、稀土组合与白莲品质的相关性，找出有利于白莲品质及产

2、量提高的相对合理稀土浓度和最佳稀土组合，为产区提高白莲品质及产量提供技术支持，建立原产地鉴别及质量安全控制体系，促进提高白莲的总体品质、国内外市场竞争力及产业的整体经济效益。同时，本项目对自然生态地质环境下原生性稀土元素在岩石-土壤-植物大系统中迁聚规律的研究成果可以丰富稀土元素生物地球化学理论，为稀土高背景地质资源开发利用和作用机理研究提供典型范例。英文摘要(限3000Characters)：Thisstudywillbeexpectedtograsptherelationshipbetweentheconcent
