| 摘 要： | 在大地热流评估中，经常要对接近地表的实测值进行校正，然而在迅速抬升剥蚀的崎岖山区，在抬升剥蚀校正基础上进一步作地形校正时，没有剥蚀静态条件下的地形校正是否仍然适用是一个没有讨论过的问题．本文以新西兰的南阿尔卑斯山地区为例，通过有限单元法数值计算，探讨了迅速抬升剥蚀的山区剥蚀和地形二者对近地表不同深度地热流量影响的综合效应．结果表明，虽然迅速抬升地区大地热流密度的地形校正与不考虑剥蚀情况下的校正在较大深度处会略有差别，但总的来说差别甚微．因此，可以沿用传统的地形校正方法，根据钻孔所处地形和测温深度作地形校正．

| Abstract: | Case study of the Southern Alps of New Zealand is carried out to investigate the combined effect of rapid denudation and rough topographic relief on subsurface heat flow. Finite element numerical simulation shows that topographyic corrections of hear flow for rapidly uplifted and eroded area have little difference with those of same relief without denudation. Traditional methods for topographic correctioon, therefore, can be applied to currently uplifted and eroded mountain regions. |
