我国轻型高山冰芯机械钻机的发展和应用

Development and Application of Light-Weight Core Drills for Ice Coring of Glaciers in High Mountains in China

通过冰芯研究可重建过去的气候环境变化,为深刻理解现在和预测未来气候环境变化提供重要的科学依据.冰芯机械钻机作为获取冰芯样品的必备工具之一,在我国高山冰川冰芯获取中发挥了重要作用.主要介绍我国自行研制的以山地冰川为主的冰芯机械钻机的发展过程和应用,存在的问题和对未来的展望.我国自行研制的BZXJ钻机性能优异,是世界上同类钻机中的佼佼者,截至2012年底已经钻取的冰芯总支数和总长度分别为125支和8 095m,为我国开展冰芯研究做出了重要贡献.

Ice core study is one of the most important means to reconstruct past climate and environmental changes and to provide the basic background for understanding present climate and projection of future situations.The ice coring drill is an essential tool for the palaeoclimatic research in glaciers.The current paper is to present the procedures of development and application for light-weight core drills for ice coring of glaciers in high mountains in China by our research group.The model BZXJ drill has cutting edge over the counterpart developed by others in the world.We have obtained 125 ice cores with a total thickness of 8 095 meters using this drill.
