| Abstract: | A fuzzy comprehensive evaluation mathematical model of water quality evaluation was built based on fuzzy mathe-matics theory. The surface water of Lanzhou was taken as subject, the water quality was evaluated on the average datas from 2009 to 2014 of surface water in Lanzhou( Anmen section of HuangHe river) , which aimed to evaluate the trend of water environment quality and the main pollutant about surface water in Lanzhou more comprehensive, to analysis the present situation of water envi-ronment quality and existing problem about surface water in Lanzhou more scientific. The results showed that the water quality of surface water in Lanzhou was improved gradually from 2009 to 2014, the comprehensive water quality assessment result of Lanzhou surface water was V from 2009 to 2010, the comprehensive water quality assessment result of Lanzhou surface water was I from 2011 to 2014, the main pollutant was total nitrogen. |
