摘要 以平顶山白龟湖湿地公园为研究对象,在研究区域布设了10个采样点,共采集29个沉积物样品,对其有机碳(TOC)、有机氮(TON)的含量进行测定和评价,同时对有机物来源进行简单分析.结果表明,沉积物中TOC含量变化范围为0.005 17%~9.602%,平均2.733%,TON含量变化范围0.014 50%~0.276 1%,平均0.101 0%,总体来说,沉积物中TOC含量随着沉积深度的增加而减小,TON含量随土深的增加而减小,C/N为6.9~75.4,平均值为24.8,沉积物中有机污染主要来源为外部来源. Taking Baigui Lake Wetland Park in Pingdingshan as the study object,in the study area we emplaced 10 sampling points,and collected 29 sediment samples. Their total organic carbon(TOC)and total organic nitrogen (TON)levels were measured. Organic pollution and sediment characteristics were evaluated,and the organic matter sources were analyzed. The results show that the TOC mass fraction varied from 0.005 17%to 9.602%,with an average of 2.733%,while the TON mass fraction varied from 0.014 50%to 0.276 1%,with an average of 0.101 0%. Overall,with the depth of deposition decreasing,the sediments TOC increases,and the TON content decreased with soil depth increases. C/N is 6.9~75.4,with an average of 24.8. The major source of sediments was an external source of organic pollution.
