- 摘要:
- 根据伊通河8个不同监测断面的水质监测数据，采用R型因子分析方法对伊通河水质进行了综合评价，研究（或分析）了河水中12种化学成分之间的相关关系，从中提取了4个主因子进行分析计算，结果表明第一污染因子主要为有机污染，包括BOD5、挥发酚、石油类等；第二主因子的主要代表指标是氨氮、NO2-N和DO；Zn、Pb分别对第三、四主因子贡献明显。分析结果从整体上认识和评价了伊通河水质的污染现状，为保护、管理伊通河水资源提供了基础理论依据。
- Abstract:
- According to water quality monitoring data of 8 different monitoring section of Yitong River, the correlation among 12 chemical components in the river were researched by using R-mode factor analysis. In this way, four main pollution factors were selected to analysis and calculate. The research showed that first polluted factor was organic pollution, such as BOD5, petroleum and volatile etc. NH3-N, NO2-N and DO were secondary important pollutants. Zn, Pb contributed for the third and fourth factors. The research provides a scientific basis for assessing, protecting and managing the water quality of Yitong River.
