Assessment of marine ecosystem health of Tianjin offshore, China

Abstract

While the marine ecosystem health is damaged by economic activities, pollution and reclamation projects, the assessment of marine ecosystem health is strongly required to facilitate its maintenance, improvement and management. In this study, the health of the Tianjin marine ecosystem was quantitatively assessed using the ocean health index in which ten public goals are considered. The results indicated that the ocean health index for the Tianjin marine ecosystem is 66, which is higher than the global ocean health index of 60. This indicated that the overall health of the Tianjin marine ecosystem is barely good and the suitable environmental management and measures should be implemented carefully and effectively in the future.
