Study on the vulnerability and its impact factors of marine fishery eco-economic system in Hainan Province
Based on the statistical data of marine fisheries in Hainan Province from 1998 to 2019,the vulnerability assessment index system of marine fishery eco-economic system in Hainan Province was constructed by using entropy weight method based on three dimensions of exposure,sensitivity and adaptability.The time change trend and influencing factors of vulnerability of marine fishery eco-economic system in Hainan Province were discussed.The results show that:(1)During the study period,the vulnerability of marine fishery eco-economic system in Hainan Province experienced a process of first increasing and then decreasing.After 2008,the vulnerability fluctuation of the system decreased,and it was in the moderate vulnerable stage,but the system vulnerability showed an upward trend after 2016.(2)The increasing pressure on the marine fishery ecosystem caused by human fishery activities led to a continuous increase in the exposure of the system during the study period.The weakening of economic and social dependence on marine fishery effectively improved the sensitivity of the system,and the enhancement of anti-interference ability and resilience improved the adaptability of the system.(3)Marine fishing and aquaculture activities,economic and social dependence on marine fisheries,scientific and technological support capacity are essential indicators affecting the vulnerability of the system.Among them,economic and social dependence on marine fisheries and the improvement of scientific and technological level are the key influencing factors of the vulnerability of the marine fishery eco-economic system in Hainan Province.
