| 摘 要： | 利用鄂尔多斯及其周缘的大地热流、地温梯度和地温分布等资料研究了其展布特征和差异性变化，并讨论了地热分布与地壳深浅构造的关系。认为，鄂尔多斯块体内大地热流、地温梯度值整体偏低，而其周缘地区则呈现出环状高值异常带。该区地震活动主要集中分布在鄂尔多斯周缘地区，即鄂尔多斯周缘存在着高热流、高地温梯度和地震丛集分布相统一的现象。这一现象说明，地热和地震活动之间存在着某种必然的联系。

| Abstract: | By using data for geothermal flow,geotemperature gradient and geothermal distribution,the distribution feature and difference are studied and the relationship of geothermal distribution with the shallow and deep structures of the crust is discussed in this paper. It is suggested that the values of geothermal flow and geotemperature gradient in Ordos block are lower,while a ring high anomaly belt appears in the vicinity of the block. The earthquake activities distribute mainly in the periphery of Ordos, that is to say,high heat flow, high geotemperature gradient and distribution of earthquakes in clusters are consistent in the vicinity of Ordos, indicating that a certain relationship exists between the geotherm and the earthquake activity. |
