In this paper, the distribution of the mantle heat flow, crust heat flow and the Moho surface temperatures in the different geologic periods were calculated on the basis of results of the thermal history of shallow sedimentary basin in combination with the theory of the geothermics. The results show that the ratio of the mantle heat flow and surface heat flow reached high peaks twice in the late period of the Early Cretaceous and the mid late period of the Paleogene, respectively, and the corresponding mantle heat flows were more than 65% of the surface heat flows. The Moho surface temperatures reached high peaks three times, 900～1100℃, 820～900℃ and 770～810℃, in the late period of the Early Cretaceous, the mid late period of the Paleogene and the early period of the Neogene(only Linqing depression, Cangxian uplift and Jizhong depression), respectively. The studies not only revealed the Cretaceous was an important period of significant change during the geologic history in the Bohai Bay Basin: the lithospheric thermal structure began to transform from "cold mantle and hot crust" type before the Cretaceous to "hot mantle and cold crust" type since the Cretaceous, but also revealed that the basin has experienced two large scale tectonic rifting. Therefore，this paper may provide the thermal parameters for the studies of the geodynamic evolution of the eastern China.
