摘要
采用对应分析方法,以石头口门水库为研究区,选取36个时间点(2003-01-2005-12,共36个月)的水质观测数据,分析计算各个时间点内对水质影响较大的污染物。分析结果表明,对石头口门水库水质有明显影响的指标是总硬度、pH值、细菌总数和大肠杆菌数。本次研究是首次将此方法运用到石头口门水库的水质评价中,而且选取的样品点为一个断面上的36个时间点,对于有效监测该断面上水质的动态变化有很大的帮助。我们可以根据获得的实时数据利用此方法得到结果,在某个时间段内对影响水质的主要污染物采用相应的处理措施,使我们对水污染的处理更加高效。
In this paper,the correspondence analysis method is adopted,the Shitoukoumen reservoir is selected as research area and the water quality observation data in 36 time points（from Jan.2003 to Dec.2005,total 36 months） are selected to analyze the influence of water pollutants in these time points.The results show that the indexes,which have obvious influence on the water quality of Shitoukoumen reservoir,are total hardness,pH value and the quantity of bacteria and e.coli.This study is the first time to adopt this method to evaluate the water quality of Shitoukoumen reservoir,and the selected 36 time points are in the same section,this is helpful to effectively monitor the dynamic change of water quality in this section.According to the real-time data,the correspondence analysis method can be adopted to analyze the main pollutants affecting water quality and take corresponding measures to deal with it in the corresponding period to get more efficient water pollution treatment.
