摘要：

随着渔业资源由单鱼种管理模式向基于生态系统管理策略的转变,捕捞因素对于鱼类群落结构的影响正逐步成为海洋生态系统的研究热点。本文主要就捕捞对鱼类群落影响的国内外研究方法进行了综述与归纳。在研究捕捞对于鱼类群落影响时,所选用的群落研究指标应符合预期性、可测性、敏感性和排他性标准,业已利用的研究方法大致可分为生物多样性、聚合特征指标、群落功能性指标、多元分析以及生态系统模型五大类。各研究方法单独使用均无法全面反映群落的结构变化,在实际研究过程中建议同时使用多种研究方法来进行鱼类群落结构的变化分析,以期全面掌握捕捞活动作用下的鱼类群落结构的实际变动状况,更好地为渔业资源的科学管理提供理论支撑。
