中文摘要： 本项目拟采用温泉水模型，模拟研究不同温度下温泉水中不同元素以纳米形式随地气流迁移的基本规律。在实验基础上，选择广东、四川、湖南或湖北3个不同地质环境下的典型温泉水储集区为地气场研究对象，以多剖面布设方式，同时利用积累式和动态地气采样，配合中子活化和等离子质谱等现代高灵敏度分析技术，获取地气场信息。结合前期工作中积累的4个隐伏构造的地气探测资料，采用微量元素示踪，模糊模式识别等数学方法，研究温泉水储集区上方地气场中元素（特别是亲水与憎水组份）的组成、分布规律，提取地气场中温泉的有效指示元素及其指标，探索其与温泉水储集区的空间关联规律，为利用地气场信息反演温泉水储集区位置提供理论依据。 在前述工作基础上，研究温泉水储集区地气弱信息提取的探测技术问题，异常场资料反演问题，初步构建有效的地气测量勘查隐伏温泉方法，并在1～2个温泉勘查区开展勘查应用。

英文摘要： In this research, a set of hot spring water model is planned to be employed for a simulation study on a basic law- - how various elements in hot spring water at different temperatures transfer with geogas flow in form of nano-particles. Based on the experiments, three typical hot spring reservoir with different geological environment possiblely in Guangdong, Sichuan, Hubei and Hunan province are chosen as the research object areas. Accumulation and dynamic geogas sampling methods are employed for multi-profile survey. The information of geogas field can be obtained by several modern analysis technique with high sensitivity including INAA and ICP-MS. Combined with the geogas survey data of four concealed structure obtained in previous works, several mathematical methods such as trace element tracking and fuzzy pattern recognition are used to study the element composition and its distribution law, specially the hydrophilic and hydrophobic components, of geogas field above hot spring reservoir. The aim is to extract the effective indicator elements and its indexes in geogas field, and to explore the spatial relative rules between the hot spring reservoir and its geogas field, which can provide theoretical basis for retrieving the location of hot spring reservoir through geogas field information. Based on above w
