前言 习惯上把海洋和陆地截然分为地球表面两大部分,它们之间以梅岸线为界,常把海岸带视为海岸线附近宽不过几十公尺的地带。近几十年来,世界各国对海岸带的理解,认为应包括海、陆相互影响的地区。海岸带的范围逐渐在扩大,美国某些州规定离岸3英里属于海岸带的范围。我国这次进行海岸带和海涂资源调查规定的调查范围;离岸向内为10公里,向外达负30米的海区。这些均为人为规定的界线。 Foreword It is customary to divide the ocean and the land into two major parts of the surface of the earth, between which they are bounded on the plum-coastline and often regard the coast as a zone tens of meters wide near the coastline. In recent decades, all countries in the world have come to understand the coastal zone and should think of the areas where sea and land interact with each other. The extent of the coastal zone is gradually expanding. Some states in the United States have set a coastline of 3 miles off the coast. This time, China conducted a survey on the provisions of the survey on the coastline and the Tu Tau resource; the offshore area was 10 kilometers offshore and reached a sea area of ​​30 meters outward. These are man-made boundaries.
