摘　　要：【目的】探究人工鱼礁投放对底层游泳生物分布的影响。【方法】于2019—2021年共进行11个航次的调查。利用物种分布模型(SDMs)研究常见底层游泳生物的出现概率、丰度、体长、体重、群落丰富度等指标与离礁距离的响应关系,归纳车由岛人工鱼礁区对底层生物的影响范围,并拟合各物种出现概率的空间分布加以验证。【结果】SDM模型显示,根据物种出现概率对离礁距离变量的响应曲线可以将物种划分为恋礁型、中间型和离礁型,恋礁型偏好分布于距离礁体0~375 m处,中间型为50~375 m,离礁型为225~879 m。恋礁型和中间型的物种丰度在离礁0~225 m处较大,离礁型为325~879 m。恋礁型和离礁型物种的体长和体重在离礁0~225 m处均较大,中间型物种为0~525 m。群落丰富度在0~225 m处较高。【结论】各物种拟合的空间分布结果与各指标对离礁距离响应关系基本一致。本研究揭示了不同底层游泳生物对离礁距离的响应特征变化,探究了不同指标下人工鱼礁的影响范围,为海洋牧场人工鱼礁的建设规划与管理提供参考依据。Artificial reefs positively affect on creating habitat,improving the water ecological environment,and enhancing biodiversity.The performance of artificial reef deployment is closely related to its biological influence scope.A total of eleven cruises of field surveys were conducted from 2019 to 2021 in the artificial reefs to explore the impact of artificial reefs on the distribution of benthic swimming species.Trap and visual census methods were both used to sample benthic swimming organisms.The response relationships between biological indicators(e.g.,occurrence probability,abundance,body length and weight of individual common species,and community richness)and the distance with artificial reefs were explored based on species distribution models(SDMs).This study summarized the influence scope of artificial reefs and fitted the spatial distribution of the occurrence probability for each species to verify the scope.The results indicated species could be divided into reef-dependent,intermediate,and off-reef species types according to the response curve between species occurrence probability and the distance with reefs.The reef-dependent species preferred to locate at 0-375 m away from the reefs,and the intermediate and offreef species types were 50-375 m and 225-879 m,respectively.The abundance of reef-dependent and intermediate species types was higher at 0-225 m away from reefs,while that of reef-off species was higher at 325-879 m.The body length and weight of reef-dependent and reef-off species were more significant at 0-225 m away from the reefs,while those of intermediate species were larger at 0-525 m.The community richness was higher at 0-225 m.The spatial distribution pattern of each species was consistent with the response relationships between indicators and the distance with reefs.This study revealed the changes in response characteristics of different benthic swimming organisms to the distance from the reefs,explored the influence scope of artificial reefs under different indicators,and provided a refe
