With the development of Marine economy，ocean development has become an important way to expand space and economic development in our country，especially in the coastal areas. Reclamation as an important way to develop and utilize marine is common in most countries，but the government and scholars at home and abroad has paid attention to the negative impact of blind reclamation. Thus，we should confront its economic benefit and negative effect，and make a reasonable reclamation control. We analyzed the management situation and existence dilemma of the reclamation，under the Fifth Plenary Session of the 18th proposed “blue bay regulation” ideas，in order to have a scientific management of the reclamation and sustainable development of the marine economy，we put forward some rational improvement strategy，establish blue ocean economic zone eventually.
