摘要
建立了模糊综合评价数学模型，针对阜新市闹德海集中式饮用水源地辽河支流柳河段上游2001年～2005年水质状况进行水污染风险评价。旨在定量分析评价阜新地区集中饮用水源地水环境质量现状和存在的问题。结果表明：柳河上游水质在2001-2005年间波动较大，主要呈Ⅰ类Ⅲ类，基本符合集中式饮用水源地水质要求。其中2003和2005年河流总磷和溶解氧超标严重，五年间主要污染物变化规律也不同，总磷呈递增趋势，溶解氧呈递减趋势。
A fuzzy comprehensive evaluation mathematical model has been established to make a water pollution risk evaluation for the water quality of the Nao Dehai central drinking-water source area of Fuxin, which is the Upper Liu River area, one of the Liao River branches, from 2001 to 2005. The aim of this paper is to make a quantitative analytic evaluation on the present situation and the problems of water quality existing in the central drinking-water source area of the Fuxin region. The result showed that the water quality of the Liu River had fluctuated from 2001 to 2005, and was mainly classified as Class Ⅰ and Class Ⅲ, which is basically consistent with the requirements for water quality standard of the central drinking-water source. The total phosphorous content and dissolved oxygen content were found significantly exceed in 2003 and 2005. The main pollutants were also different in varying order, the concentrations of total phosphorus were found increasing steadily in those five years, while the dissolved oxygen showed a tendency of decreasing gradually .
