摘　　要：大地热流是地球内部热能在地表热显示中最综合的参数. 热流数据不仅是地震学信息的重要补充(为岩石圈厚度、地球物理性质和构造演化等提供了强有力的约束), 而且, 它还对地热资源靶区优选和评价提供了重要支撑. 大地热流的测量和汇编是地热学研究中一项基础而关键的工作. 我国大地热流已公开发表四版数据1166个. 本文在此基础上, 收集公开发表的大地热流数据1096个, 实测热流数据75个. 同时, 本次研究更新了中国大地热流数据质量分类标准, 根据最新的分类标准, 在2337个大地热流数据中, A、B、C和D类数据占比分别为35.4%、40.9%、18.7%和5.0%. 除去C类和D类数据, 热流值变化范围为25.1~242.0 mW·m^(-2), 均值为63±16 mW·m^(-2);如果考虑构造单元面积和热流质量的因素, 全国大地热流加权平均值为67±16 mW·m^(-2). 分析表明, 我国大地热流分布格局表现为以下特点: 西南和台湾地区极高(≥75 mW·m^(-2))、中国东部和中北部地区高(65~75 mW·m^(-2))、中南部地区低(50~65 mW·m^(-2))、西北地区最低(<50 mW·m^(-2)).Terrestrial heat flow is the most integrated parameter in the thermal display of the Earth's internal heat energy at the surface. Heat flow data are not only a key supplement to seismic information, providing strong constraints on lithospheric thickness, geophysical properties and tectonic evolution, but also an important support for the selection and evaluation of geothermal resource targets. Measurement and compilation of terrestrial heat flow is a basic and key work in geothermics. In this paper, we collect 1096 published heat flow data and 75 measured data on the basis of 1166 published four versions of heat flow data in China. Meanwhile, this study updates the quality classification standard of China's heat flow data. According to the latest classification standard, among the 2337 heat flow data, the proportions of class A, B, C and D data are 35.4%, 40.9%, 18.7% and 5.0%, respectively. Excluding the data of categories C and D, the heat flow values range from 25.1 to 242.0 mW·m^(-2), with an average value of 63±16 mW·m^(-2);if the area of tectonic units and the quality of heat flow are taken into account, the weighted average of the terrestrial heat flow in China is 67±16 mW·m^(-2). The analysis shows that the distribution of heat flow in China is characterized by the following features: very high in the southwestern part of the country and Taiwan (≥75 mW·m^(-2)), high in the eastern and north-central part of China (65~75 mW·m^(-2)), low in the south-central (50~65 mW·m^(-2)), and lowest in the northwestern part of the country (< 50 mW·m^(-2)).
