Abstract
This paper analyzed the visual range and arrangement of light buoy on navigation officers as the primary material to establish the standard of optimal arrangement of light buoy on the channel of the domestic trade-port. About $30{\sim}150$ questionnaires by port were distributed according to the scale of trade-ports and then Effective total 356 copies were used in analysis. The distance, $2{\sim}4$mile, occupied the highest percentage 55.0% as the visual range with naked eyes at the daytime in bright weather. At the arrangement way of light buoy the both sides buoy method showed high in the preference 62.1% among the respondents. The preferred interval between sequence buoys was averagely 1.09mile. Also, the preferred number of light buoy was two in the preference 40.6% among them to cognize without binoculars.
