Based on the multi-intelligence simulation modeling method，we establish the whole process simulation model on ship’s in/out of relative areas of Lianyungang Port，by which we quantitatively evaluate the possible long-term impact on navigational induced by the LNG terminal，and compare the result with existed research conclusions. By comprehensive comparison of essential factors including waterway conditions，location and rear city distance，navigation impact，etc.，we propose the recommended site of the LNG terminal of Lianyungang Port. The analysis method and conclusion proposed provide technical support for the layout planning of regional LNG terminals.
