海岸带从自然的角度来划分,是以海陆相互影响所波及的地方为界限。在这个范围内,以潮间带为中心包括部分浅海和陆地,但从整个沿岸的社会、经济、科技等活动作为一个系统来考虑,可以认为,广义的海岸带应扩展到以沿海城镇为中心的经济区 The coastal zone is divided from the natural point of view and is based on the areas affected by the mutual influence between land and sea.

It can be considered that the broad coastal zone should be extended to include the coastal towns as the center Economic Zone
