      In recent decades,the utilization of the Yellow Sea fishery resources has obtained rapid development.As an important aquaculture and marine fishing area,the Yellow Sea ecosystem pro-vides us with abundant seafood.The amount and value changes of aquatic aquaculture and fisheries capture of the Yellow Sea were analyzed with provisioning services assessment method.Results showed that from 1990 to 2015,the amount and value of aquaculture in the Yellow Sea area continued to rise.The amount of aquaculture in 2015(8.831 million tons)has risen by 752.4%than that in 1990(1.036 million tons),while the value was up from 13.01 billion yuan to 183.44 billion yuan.Meawhile,the amount and value of fisheries capture increased and then declined,which peaked in 2000(5.307 million tons,277.23 billion yuan).The changes of aquaculture value percentage constitutes was very significant.The main components transformed from shellfish,shrimp and crabs to shellfish(45.8%)and other classes(32.8%).The value proportion of the other classes and cephalopods of fisheries capture also rose to 24.9% in 2015,which was second to the value of fish.The use of the Yellow Sea fisheries and global climate change,pollution of inshore water,rapid development of breeding technology were inseparable.The study would provide the theoretical basis for further study of the Yellow Sea fisheries utilization,management and sustainable development.
