摘要：

对于黄骅港能否扩建为大港的问题曾有过不同的看法。笔者曾多次亲临现场踏察并分析研究了大量的调查研究资料,对拟建港址的海岸性质和特点从历史和现状进行了分析研究并指出:大口河海岸属蚀退型粉砂淤泥质海岸,且已渐趋平衡,在该处建港有利。黄河输沙对此地无影响,但本世纪初黄河在此入海时的泥沙至今仍大量残存在河口处,在波浪掀动下可由潮流和余流向大口河方向搬运。漳卫新河和宣惠河入海泥沙对大口河岸无重要影响。但具体港址定于何处,并按何种方案设计仍需权衡利弊方能确定。

There have been different views on the extension of Huanghua Port into a large port. The author went many times to the proposed site for investigations and studied various data and information. The coastal nature and properties of the proposed site were carefully studied and analysed from a viewpoint of history and current situation. It is pointed out that, the coast along Dakou River estuary is an erosively recessional coast with silty sand and muck and the eroding and receding of the coast has gradually become equilibrium. It is advisable to build a port in this area. Though the deposit transportation from the Yellow River has no effect on the area,a large amount of deposit left by the Yellow River, when it flew into the sea in the area at the turn of the century, still remains outside the estuary. The deposit,lifted by waves,may be carried by tides and residual currents towards Dakou River. The deposit carried by New Zhangwei River and Xuanhui River into the sea has no significant effect on the coast of Dakou River. However , the actual site for the port to be built and the designs to be adopted should be decided only after their advantages and disadvantages are carefully considered.
