| 摘 要： | 为提高黄土塬地区窖水水质,保证窖水饮用安全,集雨水源地的选择势在必行。本文通过应用主成分分析法,研究了优质集雨水源地和决定水质的控制指标。结果表明,在不同类型集雨水源地中,水泥地面和瓦屋面的综合主成分得分分别为-3.350和-1.945,污染程度分级结果为轻度,是集雨的最佳场地;COD、NH4+-N、TP、SS和粪大肠菌群在主成分中具有高荷载值;集雨水受有机物质、地表尘土、人畜粪便污染明显,与人为活动密切相关。最后,就集雨水源地在政策法规、水质保护技术体系、水质检测和保护等方面提出了改善措施和建议。

| Abstract: | To improve the water quality and make sure the drinking safety of cellar water in Loess Plateau,the selection of the water sources for harvesting rainwater is imperative.By the method of principal component analysis (PCA),this paper determined the high-quality rainwater sources and the related control indices.Among the different types of test water sources,cement ground and tile roof were the better fields for harvesting rainwater,with their integrated principal component scores being-3.350 and-1.945,respec... |
