基于地貌分类的黄河源区多年冻土层地下冰储量估算
Estimation of permafrost ice reserves in the source area of the Yellow River using landform classification
摘要
Abstract
Ground ice is a distinguishing characteristic of permafrost soil. As permafrost profoundly influences the hy-drology, ecology and engineering design in cold regions, it is important to accurately estimate the underground ice re-serves of permafrost. Thus, this study investigated landforms and their genetic types in the source area of the Yellow River. The lithologic composition and water content were analyzed using field data from 105 boreholes. The underground ice reserves at depths of 3. 0—10. 0 m were estimated in the source area of the Yellow River. This re-search also focused on the spatial distribution of shallow underground ice. The results show that ① the total amount of ice reserves at depths between 3. 0 and 10. 0 m was approximately (49. 62±17. 95) km3 and the ice reserve per unit was (0. 293±0. 107) m3; ② in the horizontal direction, high ice contents were associated with lacustrine-marshland plain and periglacial hill landforms, while low ice contents correlated with erosional platform and alluvial-proluvial plain landforms; and ③ in the vertical direction, high ice contents were observed close to the upper limits of perma-frost and gradually decreased with depth.关键词
