Abstract: In this paper some heat flow values the geothermal in the Bohai sea and adjacent region are described.The temperature distribution, geothermal gradient and heat flow in this region have a tendency of increasing gradually from the land to the sea. This tendency is well correlated to the geotectonic features and the structure of the crust and upper mantle, and approximately coincident to the features of other geophysical field in this region. It is suggested that the possible upwelling of the material from the upper mantle in this region, especially in some segments of Tangchen-Lujiang fault belt, caused the deep parts of the crust different in temperature and density, leading to high concentration of thermal stress.

摘要： 本文描述了渤海及其邻近地区的地热状况,指出该地区的地层温度、地温梯度和大地热流有从四周向渤海逐步地升高的趋势,其与地质构造特征和地壳上地幔结构可相对应,与其它地球物理场特征大致吻合。并提出该区尤其是郯庐带的某些地段可能有上地幔物质上涌,引起地壳深部产生很大的温度差异和密度差异,造成热应力的高度集中。
