摘要
南极冰下地形测绘在国际上还没有全面开展,获取南极冰下地形为研究南极冰盖运动机理,了解南极冰下全貌具有重要意义。本文通过对南极Dome A核心区域冰下地形测绘实践,并对冰下地形图成图方法进行阐述,得出适合现阶段南极冰下地形测绘的最优方法——深冰雷达探测法。通过严密的规划测线,可以勘测不同比例尺和精度的冰下地形图,直观地获取冰下形态,为研究南极冰盖运动机理提供重要依据进行。
Internationally ,subglacial topography surveying and mapping has not been comprehensively carried out in Antarctic ,which is the key of research on the ice sheet motion to obtain the whole subglacial topography .T his paper gives the optimal method at the present stage through summarizing subglacial topography surveying and mapping in Dome A area ,Antarctic .At the same time ,a simple method of subglacial topography mapping is provided .
