Abstract: Surrounded by land on three sides, the Bohai Sea has become the area with the most intensive reclamation activities. Although brought considerable land resources, the reclamation has also led to the continuous deterioration of the regional ecological environment. In 2018, the State Council issued “Notice on Strengthening the Protection of Coastal Wetlands and Strictly Controlling Reclamation”, which proposed to prohibit the development of reclamation in the Bohai Sea and speed up the handling of historical and problematic reclamation. Based on the practical experience of Dalian Jinpu new area, this article summarizes the key points of unifying the measurement, strengthening the departmental cooperation, carrying out diversified ecological restoration and establishing the whole-process supervision system for handling of the historical and problematic reclamation problems in the future.
