港口作为国家重要的基础设施,在国民经济的发展中起着战略性作用。我国拥有丰富的港口资源,已开发利用的港口码头数量呈逐年递增趋势。据统计,至2005年底,全国港口已拥有万吨级以上生产泊位1030个,新增港口吞吐能力5.4亿吨。然而港口的吞吐能力仍嫌不足,沿海港口总能力仍缺口5 As a national important infrastructure, the port plays a strategic role in the development of the national economy. China has abundant port resources, and the number of port terminals that have been exploited has been increasing year by year. According to statistics, by the end of 2005, 1030 production berths above 10,000 tons have been set up in the ports of the whole country, and the throughput of new ports has been increased by 540 million tons. However, the throughput capacity of the port is still not enough, and the total capacity of coastal ports is still in short supply5
