description The invention discloses a method for judging the traffic operation state of an inland waterway. The method comprises the following steps of: obtaining relatively complete ship flow and density arrays reflecting the ship traffic flow in a free flow stage and a non-free flow stage by utilizing an inland ship following experiment and a ship traveling record in an unblocked stage; performing two-dimensional clustering on the ship (flow and density) array by using a two-dimensional clustering algorithm, and judging the optimal classification number of the traffic operation state of the inland waterway according to the contour coefficient; and giving a division suggestion value of the two-dimensional parameters of the flow and the density as a division critical domain of each state classification, and obtaining a channel ship (flow and density)-based inland waterway traffic operation state judgment standard. The method fills the blank of inland waterway traffic operation state identification and threshold value, is
