分析黄河三角洲潮滩湿地大型底栖动物群落时空变化特征,有助于了解黄河三角洲潮滩湿地生境质量状态,以及湿地生态系统对环境变化的响应特征.通过文献集成分析,探索了近20年黄河三角洲潮滩湿地大型底栖动物群落变化特征.结果表明:大型底栖动物群落的优势种发生了明显转变,优势种个体体型有变小趋势.群落的密度和生物量随着研究区域的不同而不同,整体上黄河三角洲北部区域(侵蚀区)高于南部区域(淤积区).北部侵蚀区域底栖动物的密度和生物量为南部淤积区域的3倍之多.群落多样性水平整体不高,且随着时间变化呈减小趋势.该研究结果有助于加深对黄河三角洲湿地大型底栖动物的年际变化特征的理解,可为评估围垦活动对大型底栖动物群落的影响提供基础数据支持.
CHARACTERISTIC CHANGE OF MACROBENTHIC COMMUNITIES IN THE TIDAL FLAT WETLANDS OF THE YELLOW RIVER DELTA IN THE PAST 20 YEARS
The analysis of the spatial and temporal changes of the macrobenthic community in the Yellow River Delta can help understand the habitat quality status of the tidal flat wetland and the response of the wetland ecosystem to environmental changes.In this study,the characteristics of macrobenthic community changes in the tidal flat wetlands of the Yellow River Delta in the past 20 years were studied through literature integration analysis.The results showed that the dominant species of the macrobenthos community changed obviously,and the individual size of the dominant species decreased.The density and biomass of the communities varied with the study area,and the northern area(erosion area)of the Yellow River Delta was higher than the southern area(sedimentation area).The density and biomass of benthic animals in the northern erosion area were three times higher than those in the southern sedimentation area.The level of community diversity was not high on the whole and showed a decreasing trend with time.This study can deepen the understanding of the interannual variation characteristics of the macrobenthos in the Yellow River Delta wetland,and provide basic data support for assessing the impact of reclamation activities on the benthos community.
