    Abstract127)   HTML5)    PDF (1178KB)(49)       Save

    To explore the current risk status of China’s pelagic fishery industry in the context of current global climate change and assess the risk level of the industry, the data related to China’s pelagic fishery industry and ocean climate change data from 2009 to 2021 were analyzed. The risk assessment index system was constructed based on the pressure-state-response(PSR) model framework, and the risk index model was applied to determine the level of pressure, state and response risk of China’s pelagic fisheries. The risk assessment results showed that the total risk index of the pelagic fishery from 2009 to 2021 showed a fluctuating upward trend due to the influence of ocean climate changes and ocean extreme disasters. The changing trend of the pressure risk index was generally similar to the change of the total risk index, indicating that climate change factors occupied a great proportion in affecting the risk of the pelagic fishery industry. The overall increasing trend of the state risk index indicated that the sensitivity of China’s pelagic fisheries to cope with climate change pressure had become greater. The overall trend of fluctuating increase in the response risk index indicated that the adaptive capacity and recovery ability of China’s pelagic fisheries themselves were gradually strengthening. Based on this, countermeasures were proposed from both external climatic factors and internal socio-economic factors, which could help enhance the risk prevention capability of China’s pelagic fisheries and provide a reference for achieving high-quality development of China’s pelagic fisheries.
