摘要
为了有效地控制饮用水源的污染,改善饮用水环境质量,保障人类的饮水健康,对水质进行评价具有十分重要的意义。确定影响饮用水质量的指标,利用主成分分析具备的在保证原始数据信息损失最小的情况下,以少数的综合变量取代原有的多维变量的简化功能,建立饮用水质量的主成分分析评价模型,以主成分的权数作为对应的污染贡献率。利用阜新市主要水源地2010年的水质监测资料对阜新市水源地水质的主要影响因子、污染原因、污染程度分别进行评价与结论分析。结果表明:影响阜新市佛寺水源地水质的主要因子为高锰酸盐指数、总磷、氟化物;农牧区的大量施肥与喷洒农药是构成水库总磷超标的主要原因。
In order to effectively control the pollution of drinking water sources,improve the drinking water environmental quality and guarantee the sanitation of drinking water,it is very important to assess the water quality.Main indexes impacting dringking water quality were identified.Then principal component analysis was used to establish the assessment model of drinking water,which could ensure that under the condition that the primitive data information was in the smallest loss,a small number of variables were used to replace the integrated multi-dimensional variables to simplify the data structure.The weighings of principal component were determinated as their pollution ratios.Based on the theoretical study of principal component analysis,used the monitoring data on water quality of the main water resources in Fuxin in 2010,the paper evaluated and analyzed the main factors affecting water quality,the cause of pollution and the degree of pollution in Fuxin.The results showed that the main factors affecting water quality of Fosi water source were CODMn,TP and fluoride.
