Abstract

Abstract

To maintain the stability of the Suaeda salsa population and their patterns, the Yellow River Delta National Nature Reserve has carried out ecological restoration projects in the degraded Suaeda salsa wetlands since 2019. Two types of restoration measures were carried out in the degraded area: microtopographic adjustment, and replenishing fresh water to reduce soil salinity. In order to evaluate the effect of the two restoration measures, we monitored and analyzed the morphological and population characteristics of Suaeda salsa, soil physicochemical properties, and macrobenthos community characteristics in the restoration project, degraded wetlands, and natural wetlands. The results showed that microtopographic adjustment was the most effective measure, while the density, coverage, and biomass of Suaeda salsa in the restoration project were higher than those in the degraded wetland, and were close to the natural wetland. In addition, the density of macrobenthos was increased, but the community structure of macrobenthos had been changed, and the diversity and evenness index decreased. On the contrary, the effect of the replenishment of fresh water was not significant, which might be caused by the interruption of fresh water.
