摘　　要：天然气水合物是继煤和石油之后的重要的、潜在的能源资源。介绍了天然气水合物在全球、我国陆域以及在南祁连盆地的分布。但是由于冻土区的气候环境、地质特征等复杂性,使得冻土区水合物的研究一时无法展开,文章详细分析了南祁连盆地的冻土区天然气水合物的形成条件、赋存环境,以及天然气水合物的形成与温度、压力、构造和沉积的关系,为我国其它冻土区天然气水合物的开发利用提供依据。Natural Gas Hydrate is a important and potential energy resource after coal and oil. In this paper, the distributions of Gas Hydrate in the whole world, our land and the South Qilian basin are introduced in detail. However, due to the complexity of climate and geological characteristics in permafrost regions, the study of Gas Hydrate in permafrost regions can not be started timely. For this problem, there is a detailed analysis of the formation conditions and existing environment of the Gas Hydrate in South Qilian basin Permafrost regions, as well as the relationship of formation of the Natural Gas Hydrate and temperature, pressure, tectonic, sedimentation, which provides a basis for the development and utilization of Gas Hydrate in our other permafrost regions.
