摘要/Abstract

摘要： 从全流域尺度上研究海河流域水体沉积物碳、氮、磷元素含量与分布特征,对研究海河流域水环境污染现状具有重要意义.本研究采集海河流域河流与水库163个表层沉积物(0～10 cm)样品,测定沉积物有机碳(TOC)、总氮(TN)、总磷(TP)的含量,运用有机指数与有机氮方法评价沉积物污染状况.结果表明: 海河流域沉积物TOC、TN、TP含量具有较大的空间异质性,下游平原区明显高于山区,北四河下游平原、黑龙港及运东平原含量较高,永定河山区、北三河山区、滦河流域含量相对较低,河流沉积物TOC含量显著高于水库沉积物,而TN、TP含量与水库沉积物没有显著差异.TN与TOC、TP含量呈显著正相关(r=0.704,P<0.01;r=0.250,P<0.01).全流域有机指数总体属于“较清洁”水平,北四河下游平原总体已接近有机污染水平.全流域有机氮总体处在“尚清洁”水平,北四河下游平原、黑龙港及运东平原流域存在有机氮污染.海河流域河流、水库沉积物具有相似的污染强度.沉积物C/N平均值为12.71,表明TOC多来源于藻类等浮游动植物,其次是高等植物,水库C/N值比河流高,陆源物质输入对水库沉积物TOC的贡献比对河流大.

Abstract: Studying the distribution of carbon, nitrogen and phosphorus of sediments on a whole-watershed scale is important to the research and management of water resources in the Haihe River Basin (HRB). In this study, total organic carbon (TOC), total nitrogen (TN), and total phosphorus (TP) of 163 samples were investigated in the HRB. Based on these data, the pollution le-vels of sediments were assessed by using different quantitative indices. The results showed that the concentrations of TOC, TN, and TP in the HRB were heterogeneous at different locations. A decreasing trend of concentrations was found from downstream plains (e.g., the Beisihe River and the Heilonggang River) to mountain areas (e.g., the Yongdinghe River, the Beisanhe River, and the Luanhe River). In addition, the concentration of TOC in river sediments was higher than that of reservoir sediments. The statistical analyses showed that TN was significantly (P<0.01) correlated to TOC and TP, with a correlation coefficient of 0.704 and 0.250, respectively. The pollution level based on organic indices was classified as the clean level in the HRB. However, the areas with a relatively high pollution level were still found in some spots, such as the Beisihe River, and the Heilonggang River. Sediments of rivers and reservoirs were similar in the pollution intensity. The average C/N value of sediments in the HRB was 12.71, indicating that the TOC was derived from algae, phytoplankton flora and fauna, followed by higher plants. The C/N value of reservoir sediments was higher than that of river sediments, indicating that the contribution of terrigenous material inputs to TOC was larger in reservoirs than in rivers.
