中国大陆地区大地热流数据汇编

大地热流是地球内热在地表最为直接的显示,并能给出发生于地球内部深处各种作用过程间能量平衡的信息,因而日益引起地球科学界的广泛兴趣和普遍关注。我国大地热流研究始于60年代,易善锋(1966)曾报道过东北中生代盆地的三个热流数据。1979年,中国科学院地质研究所地热组正式公布了我国第一批大地热流数据25个。近十年来,不同单位和作者在华北、东北、攀西、西藏等地区又先后获得了一批热流数据。最近,本文第一作者受国际热流委员会的委托,负责将我国大陆地区热流数据进行汇总并作统计分析,以便纳入“世界热流数据汇编”。

COMPILATION OF HEAT FLOW DATA FOR CONTINENTAL AREA OF CHINA

In this paper, alltogether 167 reliable heat flow data were compiled from published and in-press references. All the data are divided into three groups according to their quality. The geographic distribution of the data is nueven, most data are concentrated in North and East China with a few meansurements in Panxi region, SW China and S Tibet. Statistic analysis of these data showed that the heat flow values in China continental area vary from 25 to 110 mW/m² if 10 abnormally high values in the lakes of S. Tibet were rejected. The mean value appears to be 63 mW/m² and a normal distribution of the compiled heat flow data is obvious.
