The food web structure prior to and following the construction of artificial reefs (ARs) in the sea area around Xiaoheishan Island was established and a comparative study was conducted using stable isotopes. A total of 49 common marine animal samples were collected and used to construct the food web. Four types of food sources were detected in this area. Following construction of the reefs, the total contribution rates of Ulva pertusa and particulate organic matter decreased by 1.4% and 1%, respectively, whereas Zostera marina/Sargassum thunbergii and sediment increased by 1.5% and 0.6%, respectively. Within two years following construction, most of the omnivorous and carnivorous consumers were getting more focused. The average contribution rates of food sources of seven species changed by greater than 10%. Within two years following construction, most of the fish trophic levels decreased and most of the invertebrate trophic levels increased.

在小黑山岛海域建立人工礁之前和之后的食物网结构已建立，并使用稳定同位素进行了比较研究。总共收集了49种常见海洋动物样品，并用于构建食物网。在该地区发现了四种食物来源。建造珊瑚礁后，百日草和颗粒有机物的总贡献率分别下降了1.4％和1％，而Zostera marina / Sargassum thunbergii和沉积物分别增加了1.5％和0.6％。建造后的两年内，大多数杂食性和肉食性消费者变得更加集中。七个物种的食物来源的平均贡献率变化超过10％。建造后的两年内，大多数鱼类的营养水平下降，而大多数无脊椎动物的营养水平上升。
