The research of this paper includes three parts: the first, according to the statistical figures about the cargo transport in recent years, it analyzes cargo transport structure and the changing law and the internal reason of cargo transport. At the same time it analyzes and calculates the change of the arriving ships" structure for a systematic and full understand of the transport demands. The second, it make a scientific forecast of the port"s future cargo capacity making use of the grey forecast system, which provides scientific basis for medium-long term development plan of the ports cargo handling capacity. It also makes some analysis and research for medium-long term development future of Zhangjiagang port in use of physical unit analising technique, looks for the scattered no-order and no-system reason of medium-long term development. On the basis of summarizing their experience, the article adopts physical unit model to make a comprehensive judgement. It has distinctive opinion of value in accord with scientific principles for medium-long term development of Zhangjiagang port.
