| 摘 要： | 目的]探讨东昌湖有机物及氮素污染动态变化。方法]选取2002～2011年东昌湖六湖区的有机物指标 BOD5与 CODCr及氮素指标NH3鄄N与TN的监测数据进行分析。结果]1～6#湖区湖水水质监测期内呈恶化趋势，主要污染因子为 TN；BOD5/CODCr比值较小，表明湖水有机污染物可生化程度较低， NH3/TN比值变化较大，六湖区 NH3鄄N 在2002、2003、2010年是引起其湖区氮素超标主要因素；六湖区 BOD5与 CODCr、NH3鄄N与 TN呈显著的正相关关系。结论]为东昌湖水质改善提供一定的理论参考。

| Abstract: | The aim was to explore dynamic changes of organic matter and nitrogen pol ution in Dongchang Lake. Method] Monitoring data, including BOD5, CODCr, NH3-N and TN, of Dongchang Lake were chosen for analysis during 2002-2011. Result] Water quality of the six lake districts showed deteriorating in monitor-ing period, and TN was the dominant pol ution factor; BOD5/CODCr ratio was low, suggesting biodegradability of organic pol utant in the lake was lower. NH3/TN ratio was higher, indicating NH3-N was a major factor causing nitrogen exceeding in 2010. In addition, correlations between BOD5 and CODCr and between NH3-N and TN in the lake districts maintained at a significant level. Conclusion] The research provides references for improving water in Dongchang Lake. |
