With the long-term data of the geodetic sea level measurements undertaken in the Dongting Basin and the recent sediment data of Dongting Lake, we analyze the tectonic subsidence rate of the Dongting Basin and the sedimentary rate of Dongting Lake. From the point of view of geomorphology and hydrogeology, we distinguish the two different spatial concepts between "the basin of Dongting Lake" and "the Dongting Basin". Then, we discuss the influences of the tectonic subsidence and the siltation on the space of storing flood of Dongting Lake and the levees. Under the circumstance of the basin of Dongting Lake encircled by levees, the capacity of storing flood of Dongting Lake will decrease due to the tectonic subsidence. The tectonic subsidence capacity of the Dongting Basin restrains the shrinking tendency of Dongting Lake to a certain extent, but the tectonic subsidence is harmful to the situation of preventing flood disasters in the region of Dongting Lake. The better quality of levees is required due to the tectonic subsidence and the siltation, and the difficulties of preventing flood disasters are increasing in the region of Dongting Lake.
Key words： Dongting Lake; tectonic subsidence; siltation; flood disaster
