Abstract：In this study,an ecological risk index system based on the pressure-state-response(PSR)model was developed to evaluate the marine ecological risk of Beibu Gulf sea area,Guangxi.Fifteen representative indicators were picked up for the ecological risk index system.Analytic hierarchy process(AHP)was used to obtain weights of the selected indicators.Marine risk index was calculated using synthetic index method.The result showed that the marine risk of Beibu Gulf sea area was at the level of early warning.Optimistically,the marine risk presented a declining tendency in recent 10 years.Some marine risk management countermeasures were put forward for marine sustainable development,which included science-based and strictly controlled land reclamation,controlling land-based pollution,controlling alien species invasion,controlling the population of coastal cities,reinforcement of coastline renovation and restoration among others.
