| 摘 要： | 通过对滹沱河流域各支流源头区地表水中氮、磷浓度监测分析,得出本底状态下总氮浓度为0.223～5.631 mg/L,氨氮浓度范围为未检出～0.634 mg/L,可溶态氮浓度为0.190～5.532 mg/L,总磷浓度为0.024～0.683 mg/L,可溶态磷浓度为0.026～0.220 mg/L.本底状态下各水文期氮的非点源污染形态都以可溶态氮为主;磷的非点源污染形态枯水期以可溶态磷居多,丰水期以颗粒态磷为主.滹沱河流域本底状态下氮、磷非点源污染水平较高. |
| 关 键 词： | 滹沱河 氮、磷 本底值 非点源污染 |

| Abstract: | The headwaters areas of all tributaries of Hutuo River,which have been slightly interfered by human being,have been taken as the major study areas in this paper.The concentration of nitrogen and phosphorus in surface water in the study areas is monitored and analyzed.The results show that under the background state,the concentration of TN is 0.223~5.631 mg/L,the concentration range of ammonian is non~0.634 mg/L,the concentration range of dissolved nitrogen is 0.190~5.532 mg/L,the concentration of TP is 0.02... |
| Keywords: | Hutuo River nitrogen phosphorus background value non-point source pollution |
