Quaternary Huarong uplift is lacated at the center of JianghanDongting Basin. Detail geologic mapping and bore data was taken to study on the landforms，Quaternary faults and deposits of Huarong uplift and its adjacent areas，and then to reveal the tectonic risesubsidenece characteristics and process. On the base of above progresses，the authors discussed the genesis and tectonic movement dynamic mechanisms of Huarong uplift. During Early Pleistocenemiddle Middle Pleistocene Huarong uplift and its peripheral sags subsided together while the uplift controlled by several peripheral normal faults rose related to the sags. The uplift and the sags rose side by side in late Middle Pleistocene，and stabilize or subsided weakly during Late PleistoceneHolocene. Huarong uplift took on obvious subsidence as a whole in Quaternary. All above indicated that Huarong uplift was caused mainly by preQuaternary basinmountain landforms，and secondly by the rise of the uplift related with peripheral sags. Geological characteristics of Huarong uplift and its periphery and regional geology references suggest that JianghanDongting Basin was a faulted basin during Early Pleistocenelate Middle Pleistocene，and a depressional basin during late Middle PleistonceneHolocene. The authors discussed and bring forward modes about the dynamic mechanisms of Quaternary tectonic activities of Huarong uplift： 1)The faultedsubsidence of JianghanDongting Basin during Early Pleistocenemiddle Middle Pleistocene were related with the movemnet of deep matter to outside under the uplifting of mantle. 2)The tectonic activities since late Middle Pleistocene were possibly related with return of the earlier transported matter，platescale matter movement and compression. 3)Unitary subsidence of JianghanDongting Basin made Huarong uplift at center of the basin subsided in the mass； on the other hand，special crust structure of Huarong uplift increased the difficulty of deep matters movement，which caused Huarong uplift rise related to peripheral sags.
