Evaluation of the Marine Ecosystem Services of the Liaodong Gulf,Bohai Gulf and Laizhou Gulf, China
The value of marine ecosystem services plays an important role in marine resources development and marine management. In this research, we use the classification method of Millennium Ecosystem Assessment, which is to divide the ecosystem services into food production, gene resources provision, oxygen production and climate regulation, waste disposal, biological control, leisure and recreation, scientific search and culture, primary production, biodiversity and habit provision. The result shows that the total economic values of 10 services of the marine ecosystem services of Liaodong Gulf, Boliai Gulf and Laizhou Gulf is RMB 14851.1 million yuan. Among them, Liaodong Gulf has the largest value, followed by Laizhou Gulf and Bohai Gulf, accounting for 56.7%, 23.3% and 20%. Food production has the largest value in each ecosystem service, accounting for 71%. It appears high relativity among che food production, oxygen production and climate regulation and primary production, because they depend an the same primary production phytoplankton and benthic algae. The valuation of marine ecosystem services in this study would help government officials to establish ihe policy of ecosystem compensation.
