珊瑚礁提供的生态系统产品和服务对数亿人的社会和经济福利至关重要，尤其是在发展中国家。广泛的珊瑚礁退化正在严重侵蚀这些商品和服务，但影响社会使用珊瑚礁方式的社会经济因素却知之甚少。我们研究了印度洋上五个国家的人口密度、社会经济发展的多维指数、珊瑚礁复杂性和珊瑚礁鱼类种群状况之间的关系。在渔场，鱼类生物量与人口密度呈负相关，但最好的解释是珊瑚礁复杂性和与社会经济发展的u型关系。中等经济发展水平地区的珊瑚鱼生物量比低、高经济发展水平地区低4倍。相比之下，关闭渔场内的平均生物量是渔场内的三倍，与社会经济发展无关。维持珊瑚礁渔业需要一种综合方法，利用保护区等工具迅速建立珊瑚礁资源，同时在较长时间内建立社会能力和资本，以解决珊瑚礁退化的复杂根本原因。
The ecosystem goods and services provided by coral reefs are critical to the social and economic welfare of hundreds of millions of people, overwhelmingly in developing countries [1]. Widespread reef degradation is severely eroding these goods and services, but the socioeconomic factors shaping the ways that societies use coral reefs are poorly understood [2]. We examine relationships between human population density, a multidimensional index of socioeconomic development, reef complexity, and the condition of coral reef fish populations in five countries across the Indian Ocean. In fished sites, fish biomass was negatively related to human population density, but it was best explained by reef complexity and a U-shaped relationship with socioeconomic development. The biomass of reef fishes was four times lower at locations with intermediate levels of economic development than at locations with both low and high development. In contrast, average biomass inside fishery closures was three times higher than in fished sites and was not associated with socioeconomic development. Sustaining coral reef fisheries requires an integrated approach that uses tools such as protected areas to quickly build reef resources while also building capacities and capital in societies over longer time frames to address the complex underlying causes of reef degradation.
