摘　　要：我国是多年冻土分布面积第三大的国家,具有良好的天然气水合物资源勘探前景。然而,陆域冻土区的天然气水合物赋存特征与海域表现出明显的差异性,有效的陆域冻土区水合物勘探技术成为水合物资源调查与评价的关键。这里聚焦陆域冻土区天然气水合物地球物理地球化学勘探进展,简要介绍了冻土区水合物勘探历程,重点介绍了中国地质科学院地球物理地球化学勘查研究所近十多年来冻土区水合物勘探取得的主要成果与进展,主要包括水合物勘探技术、识别标志、储层评价方法、勘查模型和水合物资源环境效应等方面内容,并结合我国冻土区水合物勘探研究现状,展望了陆域冻土区水合物研究发展趋势。China is the third largest country in the distribution areas of permafrost,which has good prospects for natural gas hydrate resources.There are obviously differences in the occurrence characteristics of natural gas hydrate between the terrestrial permafrost regions and marine regions,thus the effective hydrate exploration technology has become the key way to the investigation and evaluation for hydrate resources in terrestrial permafrost regions.This paper focuses on the advances in geophysical and geochemical exploration of natural gas hydrate in terrestrial permafrost areas.Firstly,the history of hydrate exploration in permafrost areas is briefly introduced.Secondly,the main achievements and progress of hydrate exploration in permafrost areas that are obtained by the institute of geophysical and geochemical exploration,CAGS in recent ten years are described.Which includes exploration technologies,identification marks,evaluation methods,exploration models and the eco-environmental effects of gas hydrate,etc.Finally,combined with the current situation of hydrate exploration and research in permafrost areas in China,the development trend of hydrate research in terrestrial permafrost regions has been prospected.
