The invention provides a laser berthing and environment monitoring system, which comprises two laser range finders, an anemorumbometer, a tide level instrument, an industrial computer and an alarm. The laser range finders are arranged in parallel and spaced by a certain distance, the laser range finders, the anemorumbometer and the tide level instrument are connected with an input end of the industrial computer, and an output end of the industrial computer is connected with the alarm. The offshore distance of a ship, the speed of the ship and the angle between the ship and the wharf are detected by the aid of the laser range finders on a wharf, environment data including the wind speed, the wind direction, the temperature, the humidity, the atmospheric pressure, the tide level, the velocity of waves, the flow direction of the waves and the like can also be monitored, and accordingly berthing operation of the ship can be guided; and an alarm signal can be displayed when the berthing speed of the ship is excessively fast or the angle of the ship is over large, so that operators and ships in a field can be reminded, and accidents causing damage to wharf (ship) facilities are prevented.
