【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。更多还原

【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.更多还原
