斜面市街地を有する港湾都市の地域特性と整備課題

抄録

From long ago, Japanese harbors were located in inlets and back bays where wave conditions are quiet, and cities developed around these harbors. Japan, however, is a highly mountainous country, and in many areas steep slopes press right down to the coast. Thisgeology influenced the form of towns and cities. In port cities that developed along coasts bordered by steep slopes, narrow stepped roads connected the harbor with the surrounding community. This presented problems in terms of disaster eveacuation and countermeasures, as well as various restraints on the daily living environment. In addition, these harbors now suffer difficulties in that they lack sufficient backlot space for storing containers, which have become the mainstay of modern high- speed, high -volume tranportation systems. Some of these harbors thus now suffer from decline of trunk industries and loss of population. To revitalize these harbar cities, a balance must be struck between the port area and the surrounding community. This basic research was designed to clarify the characteristics of harboe cities built on steep slopes, and to suggest directions for revitalizing them. The results identified distinct differences between these and harbor cities with more flat land.
