A Study on Life Cycle Assessment of Port

本研究探讨了近年来我国港口改造的理想途径。1995年坂神淡路大地震后，人们对港口的吸引力不足提出了强烈的不满，日本开始了以深水泊位为基础的高标准港口的建设。以这样的全国规模的港口建设是否有必要、是否是再合适的规模为目的，开始了对我国港口包括腹地的经济状况进行尽可能多的考察和调查的研究。1997年调查的港口是11个港口中的5个区域，次年又对4个港口中的3个区域进行了考察和调查。通过这一实地研究，很好地证明了我国港口改造已经作为社会资本得到了改善。接下来，作者考察了港口是否存在生命周期。如果港口处于衰退期，即使在大型港口，也会出现改善后的货运流量变得无用的情况。此外，也可以通过多变量分析来明确港口经济对地方政府的影响程度。但是，无法实现港口发展的生命周期评价。由于作者在研究的中间点改变了车间方面。因此，作为废物处理场对环境的影响和对环境的贡献，再次遭遇衰退期的港口的作用以及在港口的开发和改善中对环境改善的贡献方式等必须作为未来的研究进行审查。

This study examined ideal way of port improvement of recent our country. In Han-Shin Awaji Earthquake disaster 1995, it cried for the lack of the attractiveness of the harbor, and the improvement of high standard harbor with the deepwater berth began in Japan. It was started that whether it is port improvement in such national scale being necessary, and whether it is an again appropriate scale were examined as a purpose.Then, the research started that the harbor in our country is inspected and is investigated as much as possible including the economic situation of the hinterland. The harbor which author investigated were the 5 regions of 11 harbors in 1997, and 3 regions of 4 harbors were inspected and were investigated in next year. By this field study, it was well proven that port improvement of our country had been improved as social capital.Next, the author examined whether there was a life cycle in the harbor. If the harbor is degeneration period, there is a case in which the freight flows becomes the futility even in large harbor on the improvement.In addition, it was possible to clarify by also using the multivariate analysis on whether the harbor economy affects how much for local government.However, it could not reach the life cycle assessment of port development, because author changed in respect of the workshop in the middle point of the research.Therefore, effects to the environment and contribution to the environment as a waste disposal site, roles of the harbor which met the degeneration period again and ways of the contribution to the environmental improvement in development and improvement of the harbor, etc. must be examined as future research.
