Method for quantitative forecasting of lake basin landforms based on flow field representation

The invention discloses a method for quantitative forecasting of lake basin landforms based on flow field representation. The method comprises the steps that major sand control geological factors are determined; according to structural characteristics of a research area, a basin is recovered according to a stratum burial history; a dynamic simulation system of a basin deposition sand body system is established based on basin recovery, and influences of material sources, hydrodynamic condition parameters and structural characteristic parameters on sand body distribution evolution are analyzed; according to different particle carrying modes, deposition substances are divided into cohesive silt and non-cohesive silt, and simulation representation of deposition compositions can be achieved; through simulation representations of the deposition compositions, three deposition conditions including deposition, denudation and no keeping after passing of the analyzed deposition substances are judged, and a deposition am
