摘要
采用模糊数学方法对黄河兰州段的水质进行评价,研究该区段水质随时间和空间变化的规律;利用已有资料分析得出:黄河兰州段水质属于地表水环境质量标准Ⅴ级,污染严重,主要污染类型为生物和有机物污染;模糊数学可用于水质动态变化综合评价,包括时间和空间两方面,与单因子浓度动态变化相比,能更全面地反映综合水质的变化,且又能指明水体污染重点防治时段和区域。
The water quality at Lanzhou section of Yellow River was evaluated by fuzzy mathematics method to study the changing of water quality with time; meanwhile, the application of fuzzy mathematics to water quality changing with space using the data available was studied. The results showed that：（1） the water quality at Lanzhou section of Yellow River belonged to V class of surface water environmental quality standard, being seriously polluted with main polluted type of biological and organic pollution; （2）fuzzy mathematics can be applied to comprehensive evaluation of water quality dynamic change, including two aspects of time and space; in comparison with dynamic change of single factor concentration, it can more overall reflect comprehensive change of water quality, and indicate the time section and region where the pollution water body should be controlled emphatically.
