摘要:
为研究石臼湖沉积物中磷元素的形态及分布特征,联合Hedley、SMT提取法与多元统计分析,对石臼湖沉积物及流域内不同类型土壤的形态磷进行测定和对比分析。结果表明:不同类型的沉积物/土壤中,磷以无机磷形态为主,其中Ca-P占比最高,Fe-P和NaHCO3-P次之,H2O-P占比最低;形态磷的含量总体呈现出河口沉积物 > 湖泊沉积物 > 农业土壤的特征。研究结果揭示了石臼湖沉积物中形态磷与流域内不同类型土壤之间的潜在联系,表明了流域内面源污染是石臼湖沉积物磷负荷的主要贡献来源。
Abstract:
In order to study the forms and distribution characteristics of phosphorus in the sediments of Shijiu Lake, the Hedley and SMT extraction methods were combined with multivariate statistical analysis to determine and conduct a comparative analysis of the forms of phosphorus in the sediments of Shijiu Lake and different types of soils within the watershed. The results showed that in different types of sediments/soils, phosphorus is mainly in the form of inorganic phosphorus, with Ca-P accounting for the highest proportion, followed by Fe-P and NaHCO3-P, and H2O-P accounting for the lowest proportion; The overall content of phosphorus forms shows the characteristics of estuarine sediments>lake sediments>agricultural soils. The research results reveal the potential relationship between the form of phosphorus in the sediment of Shijiu Lake and different types of soil in the watershed, indicating that non-point source pollution in the watershed is the main contributor to the phosphorus load of Shijiu Lake sediment.
