| 中文摘要: |
| 选取五源河上、中、下游底泥进行取样，系统分析底泥样品的物理参数、营养参数、有机
污染物和重金属。分析结果表明，底泥中有机质含量达到土壤三级标准，中游底泥样品有机质含
量最高（34.4 g/kg），底泥中有机磷和速效钾含量丰富达到土壤一级水平，但有效氮含量匮乏，仅达
到土壤五级水平，样品中未检出有机污染物。重金属污染采用潜在生态危害指数评价法进行评
价，评价结果表明测试底泥中Cd<8，RI<150，属于清洁水平。综合分析底泥物理参数、营养参数和
污染物水平，五源河上下游底泥可做建筑填土使用，中游底泥可做种植土壤利用，但应适当补充
氮肥。 |
| 英文摘要: |
| Sediments were selected from the upper, middle and lower reaches of the Wuyuan River, and the physical pa⁃
rameters, nutrient parameters, organic pollutants and heavy metals were analyzed. The results showed that the organic mat⁃
ter content in sediments reached the third-grade soil standard, and the organic matter content of midstream sediment sam⁃
ples was the highest (34.4 g/kg). The content of organic phosphorus and available potassium in sediments was rich enough
to reach the first-grade soil level, but the content of available nitrogen was scarce, reaching the fifth-grade soil level, and
no organic pollutants were detected in the samples. The pollution condition and potential ecological risk of heavy metals
were evaluated through potential ecological risk index evaluation method. The results showed that the pollution degree was
Cd <8 and potential risk index was RI < 150, the bottom muddies were in pollution-free levels. Based on the comprehensive
analysis of sediment physical parameters, nutrient parameters and pollutant levels, the sediments in the upper and lower
reaches of Wuyuan River could be used as materials for building fill, and the sediment in the middle reaches could be used
as planting soil, but nitrogen fertilizer should be supplemented appropriately. |
