应用海洋健康指数对环北部湾中国近岸海洋健康的评价

本研究在环北部湾中国近岸海域生态系统调查基础上，利用国际前沿的理念—海洋健康指数（ocean health index，OHI）评价环北部湾中国近岸海洋的健康状态。评价结果:环北部湾中国近岸海洋健康指数的评估总分为61.3分。其中，得分最高的为清洁水域，得分92.5分，其次为自然产品得分85.6分。海洋归属感和旅游休闲的得分也高于70分。但食物供给和生物多样性方面得分不足60分，海岸防护、碳汇、海岸带生计与经济方面得分不足50分，传统渔民的捕捞机会的得分仅39.3分。上述结果说明环北部湾中国近岸海洋健康状况整体较差，特别在食物供给、生物多样性、海岸防护等得分不足60分的6个方面，问题较为严重，应加强管理与保护。

Assessing the health of Beibu gulf rim,coastal South China Sea,with a scale application of the ocean health index

Health of Beibu gulf rim of coastal South China Sea was assessed with a scale application of the ocean health index (OHI).The results showed that the overall region ocean health scored 61.3.Highest scoring goals included clean waters (92.5) and natural products (85.6).Medium scoring goals included sense of place (78.9) and tourism and recreation (76.6).However, six goals included food provision, artisanal fishing opportunities, carbon storage, coastal protection, coastal livelihoods and economies and biodiversity scored lower than 60, which the lowest scoring goal was artisanal fishing opportunities (39.3).The results suggested that ocean health of the overall Beibu gulf rim, coastal South China sea was poor.In particular, the government should take more measures to protect and manage the six goals scored lower than 60.
