摘　　要：海草床是全球分布最广泛的滨海湿地生态系统,提供着重要的生态服务功能。但是近年来,在人类活动和气候变化的双重作用下,海草床不断退化。食物网是海草床生态系统的重要组成部分,研究食物网营养级之间的相互作用关系对于海草床的生物多样性和稳定性具有重要的意义。通过检索Web of Science和CNKI数据库中收录的海草床食物网营养级相互作用关系的相关文献,从研究区域、种类分布、营养级相互作用类型、环境影响因子以及研究方法等方面进行了文献分析,以期阐明国内外海草床食物网营养级研究相关进展。结果表明:目前的主要研究区域具有一定的地域性,以保护和恢复较好的区域为主;研究的海草种类主要为广泛分布的种类;研究的相互作用类型主要为食物网的部分环节,缺乏对整个营养级动态变化的研究;研究考虑的环境因子主要是富营养化的影响,而对于其他环境因子的动态变化涉及较少;目前的研究方法以模拟实验为主,多偏向于静态或者短期的模拟,缺乏对长期动态变化过程的模拟研究。Seagrass meadows are recognized as the most widely distributed coastal wetland ecosystems in the world and play an important role in ecological service.However,in recent years,seagrass ecosystems have been significantly affected by natural and anthropogenic factors,and experienced significant degradation.Food webs are important parts of the seagrass ecosystems and studying the trophic interactions of food webs have great significances for the biodiversity and stability of the seagrass meadows.In the present work,the literatures on the trophic interactions of seagrass food web based on Web of Science and CNKI databases were analyzed.The study areas,species of seagrass,types of trophic interactions,environmental factors and study methods of literatures were analyzed to point out the research progress of seagrass food webs.The result shows that the main study areas were areas being well protected;the main seagrass species were species being widely distributed;the main trophic interactions types were mainly part of the food web,lacking the whole trophic levels;the environmental factors be considered were mainly the impacts of eutrophication,while the other dynamic environmental factors were less involved;the research methods were considered mainly simulation experiments,mostly biased towards static or short-term simulation,which was lack of simulation studies of long-term dynamic processes.
