摘 要:运用模糊综合评判法对哈尔滨松北湿地进行全面评价,结果表明:水质主要属Ⅳ类水质,不能满足湿地功能利用的水质要求。其污染原因,主要与近年来工农业生产快速发展而大量排放污水和工业废水有关。为此,需要加强湿地区域污染源的治理,以确保松北湿地水环境的安全。The assessment of water quality in the urban wetland of Harbin city on north shore of Songhua River using the fuzzy synthetic evaluation method was presented in this paper. The results indicated that water quality level mainly was Ⅳgrade and could not suit for water use of taking its corresponding function of wetland. By analyzing underlying reasons, pollutants discharging into the water body due to increased industrial and agricultural activities contributed to emissions sewage and industrial waste water.
