The research is to examine and revise the Draft Articles of Coastal Zone. There are some defects in the Draft Articles. The major one is that the concepts of the preserved coastal area and the protected coastal area fail to achieve the goal of the Draft Articles as a whole, which is to maintain the balance between the preservation and the exploitation of coastal zone. A new concept, the intergrated management plan of coastal zone, should replace the preserved coastal area as well as the protected coastal area. Based on the idea of intergrated management plan of coast zone the whole legal system governing the preservation and the exploitation of coastal zone should be constructed.
