摘　　要：为了更好地管理与保护湿地公园的生态环境,本研究以海口美舍河国家湿地公园为研究对象,探究2019—2021年土壤沉积物的物理性质、养分含量、重金属含量的时空分布特征并进行讨论。结果表明:土壤沉积物的物理性质没有显著性变化,并且在各采样点中,以下游采样点土壤沉积物的物理指标变化最大;土壤沉积物中全氮和全磷的含量基本保持稳定,有机质含量表现为下游>上游>中游;土壤沉积物中Cu和Zn的含量均高于所参考的背景值,并且在下游的累积现象较为严重。相关分析结果表明,土壤沉积物的各项指标之间存在相关性。In order to better manage and protect the ecological environment of the wetland park,this study took the Haikou Meishe River National Wetland Park as the research object to investigate and discuss the spatial and temporal distribution characteristics of the physical properties,nutrient content and heavy metal content of soil sediments from 2019 to 2021.The results showed that there was no significant change in the physical properties of soil sediments,and the physical indicators of soil sediments in the downstream sampling points changed the most.The contents of total nitrogen and total phosphorus in the soil sediments remained basically stable,and the content of organic matter showed downstream>upstream>midstream.The contents of Cu and Zn in soil sediments were higher than the reference background values,and the accumulation was more serious in the downstream.The results of correlation analysis showed that there were correlations between the indicators of the soil sediments.
