Abstract： The dispersal of plants， animals and other organisms in aquatic ecosystems has become one of
the most active research fields in recent years，as the essential dispersal mode of riparian vegetation，hydro⁃
chory can make long-distance migration of millions of propagules，and create suitable conditions for subse⁃
quent establishment and growth. In this paper the propagule is selected as typical living organism， the
main medium and pathway of its dispersal have been summarized and analyzed. Further，the periodic hydro⁃
chory of propagules are summarized and its role in dynamics of plant community， interference factors of
which are summarized and analyzed，and dynamics characteristics of the propagule in hydrochory have also
been depicted. The means and characteristic methods of long-distance transport， the existing condition and
problems of which are analyzed in the study. The essential mechanisms of hydrochory are dissected in the
view of hydrodynamics，and their roles in building integrated coupling models are clarified.
Keywords：plant propagator；hydrochory；hydrodynamic transport；ecological restoration
