Research on Water Quality Assessment of the Reservoirs,Total Nitrogen and Total Phosphorus Forecast in Luan City

WANG Wan-fen et al(Department of Urban Construction and Environment Science,West Anhui University,Luan,Anhui 237012)  
Water quality was assessed by adopting improved fuzzy comprehensive evaluation method,i.e.minimum membership method,according to the monitoring data of five major reservoirs in Luan City.And the evaluation factors were determined by share rate of pollution method.The GM(1,1) grey model was established to forecast total nitrogen and total phosphorus concentration in the future.The results indicated that the quality of the five reservoirs in Luan City reached the grade II of national water standard in 2007.Total nitrogen concentration of Meishan Reservoir showed the downtrend in 2002-2012 while that of Mozitan,Longhekou,Xianghongdian,Fuziling Reservoir showed the significant uptrend since 2003.Total phosphorus concentration of Fuziling and Mozitan Reservoir showed the uptrend while that of Longhekou,Xianghongdian,Meishan Reservoir showed the downtrend.
