| 摘 要： | 利用低温热年代学数据计算造山带剥露速率时需要考虑热流、地形、放射性物质的生热等因素,因此近20年来发展起诸多计算方法,包括矿物对法、年龄高程法、Turcotte法、Stüwe法、Mancktelow法、谱分析法、有限元三维模拟等。其中，当地温场处于稳态时，对于钻井或垂直剖面连续采样可采用年龄高程法，对于二维有周期性地形可采用Turcotte法、Stüwe法、Mancktelow法，对于二维非周期性地形可采用谱分析法，有限元三维模拟适合于求取区域剥露速率。

| Abstract: | When calculating the exhumation rates of orogenic belts, some factors should be considered including heat advection, topography, radiogenic heat production, etc. As a result, many methods have been developed in the recent two decades, including the age elevation relationship, the Turcotte's, the Stüwe's, the Mancktelow's, the spectral analysis, the finite element analysis method, etc. When the geothermal field is in a steady state, age elevation relationship is applicable to the consecutive sampling of vertical section. The methods of the Turcotte's, the Stüwe's, and the Mancktelow's are applicable to the 2 D periodic topography. The spectral analysis is applicable to the 2 D non periodic topography. And the finite element analysis is applicable to the calculation of regional exhumation rates. |
