Abstract

This study was carried out to evaluate the water quality of West Lake in Guangdong Ocean University with the method of single factor and comprehensive water quality identification index based on the data investigated from four sampling sites in May, September and December of 2013 and March of 2014. The results indicated that: The main pollutants of West Lake are total phosphorus (TP), total nitrogen (TN) and permanganate index(CODMn). TP is the key pollutant of West Lake. The single factor water quality identification index of TP is from 6.21 to 9.44. The water quality is worse than the national quality standards for ClassV in all the monitoring sites and time. The water quality of TP is 1 to 4 grade worse than water environment function zone of West Lake . The water quality shows regular change trend in different monitoring time. The water quality at wet season, i.e. May and September is better than that at dry season, i.e. December and March. The highest comprehensive water quality identification index value of 6.331 appears in December, and the lowest is 4.310 in September. The main influence factor of the water quality is the externalÿsourceÿofÿpollution from the domestic sewage of the dormitory and cafeteria. Strengthen the management of the domestic sewage is the valid measure to improve the water quality of West Lake.
