Abstract

Abstract

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.
