Abstract: Relative changes of lake-level in continental basins are complicated controlled by multiple variablessuch as tectonic subsidence, absolute lake-level change, deposit supply and climate.Perhaps the waterlevel of lake basin is more significantly influenced by tectonic variation than that of sea basin because ofthe nonbalanced tectonic subsidence.With the total water volume of lake neglected, five changes of single-faulted basins would happenwhile blocks tilt: (1) regression at gentle slope;(2) transgression at steep slope;(3) deepening of waterbody in the centre of a lake;(4) broadness of lake-level and (5) growth of capacity.Some practical datahave proven these preliminary conclusions.
