Abstract：To the purpose of scientifically and rationally evaluating the light environment quality of the ships navigation at night is to control the light pollution at sea and ensure the safety of the ships navigation at night.Through the literature analysis and expert advices,the corresponding evaluation indexes were screened out.The Likert scale and Matter Element method was used to evaluate the light environment of the ships navigation at night objectively,based on the classical and regional domains of the light environment,the correlation grade of the corresponding evaluation interval was calculated according to the specific value of the evaluation index in the light environment to determine the pollution level of the sea.Then,the Hangzhou Bay Bridge is selected as the example,whose light pollution level of the main channel bridge is Ⅲ,and the pollution level of the sea platform is Ⅲ,and the light pollution level in the south and north bridge is Ⅱ.The light environment of ships navigation at night evaluation system not only applies to the waters of cross-sea bridge,but also can widely be used in port,waterway and other waters of the light environment evaluation.
