| 中文摘要: |
| 考虑到水库饮用水源样本并没有严格的属性,以及它们在形态和类属方面存在着中介性,确定了对人类生理健康影响较大的高锰酸盐指数、大肠杆菌、总氮、氨氮、总磷、溶解氧6项评价因子;通过构造判断矩阵及一致性检验,判断专家意见的一致性,有效地将定性分析与定量分析的结合,从数学分析的角度上给出了各个指标比较的数量关系;将评价因子层指标的权重与模糊数学模型结合,建立城市水库水质评价的模糊AHP法数学模型。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适用性分析。结果表明:影响阜新市水库水质的主要因子为高锰酸盐指数、总磷、总氮;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。 |
| 英文摘要: |
| In consideration of non-strict attribute and betweenness for drinking water source form and class attribute, nine assessment factors which have much more influence on human health were identified, for example, permanganate index, Escherichia coli, total nitrogen, total phosphorus, dissolved oxygen and so on. Through constructing the judgment matrix and consistency checking, judging the consistency of expert opinions, effective combination of qualitative and quantitative analyses, from the angle of mathematics analysis, the authors presented the numerical relationship between the comparisons of various indexes. The evaluation factor level index and fuzzy mathematics model based on AHP method combination help us to establish the city reservoir water quality fuzzy assessment model. Using water quality monitoring data from Fuxin City main water sources in 2010 the authors evaluated the main factors affecting Fuxin City water quality, the causes of pollution, pollution levels, respectively and also conducted applicability analysis. The results showed that the main factors affecting Fuxin reservoir water quality are the permanganate index, total phosphorus and total nitrogen in agricultural and pastoral areas. The intensive fertilizing and spraying pesticides is the main reason why reservoir's total phosphorus exceeds the standard. |
