摘　　要：本文根据我国沿海煤炭运输的实际情况及港口的自然条件,从单船和港航综合两个角度出发,比较分析了自卸船与常规散货船的经济性,从而给出了自卸船在我国沿海煤运中以装卸效率、自卸设备比价和停港时间为参数的由载重量DW和航距R表达的自卸船适用性图谱,并作了敏感性分析。本文给出的图表有一定的实用性。Based on actual conditions of sea-transport of coal and natural conditions of ports in our country, this paper describes the economics of selfunloading vessels in comparison with that of general bulk-carriers at two different angles, i.e. (1) ship only and (2) ship-ports jointly. Utility charts of self-unloading vessels for sea-transport of coal in China are privided in terms of deadweight and voyage distance with loading/unloading efficiency, self-unloading equipment rated price and ship mooring period as parameters. Sensitivity analyses are performed. It is hoped that the charts and the computer programme provided in the paper may be of certain practical use.
