Six Taking The Yangtze River Estuary Waters Navigation Management Research

Along with our country economy continues to expand and steady growth of trade volume ,and the size of the inland waterway transport is increasingly growing. The Yangtze river and the Beijing-hangzhou grand canal is known as the "golden waterway"in china, each year a large number of goods are transported from the economic hinterland. estuary of liuwei is the confluence of the Yangtze river and the grand canal,while convenient the exchanges between the water ship, also caused waters vessel traffic complex,frequent accident. In addition,varied types of ships sailing in the intersecting water and a large number of flotilla sailing here, increased the difficulty of the Navigation management in this waters.estuary of liuwei is hub waters in our country inland waterway transport, the ship flow from the canal and the Yangtze river meeting here. At the same time, the waters of the navigation environment is complicated, in addition to the estuary of the rivers, also contains anchorage zone, Yangzhou wharf, anchorage of dingyizhou and the special route for upside vessel etc. with affected by the Yangtze river water flow, main channel convex near to the estuary, in under the common influence of many factors, the waters of the ship navigation and the ships meeting situation is quite complicated, bringing larger risk in this waters.Based on investigation and analysis situation in estuary of liuwei in Yangtze river'navigable at present, in-depth discussion of the communication and navigation in the waters from the current ships, study the factors affecting at the navigation safety,explore the achievements and shortcomings of current navigable management, analysis tihe concrete factors influencing in navigation safety .At the same time, refer to the domestic and foreign research achievements of scholars about the water traffic and management, combined with the actual situation of the estuary of liuwei, provide the advice about manage the vessel traffic flow and configuration navigation resources in this waters. Its research also can be used at the navigation of the ship management,specification of vessel traffic flow, ensure the safety of navigation of ships, reduce the risk of navigation, maintenance the shipping order and security along the economic development has a positive meaning.
