Abstract
Based on the water quality monitoring data in February,May,August and October in 2016,comprehensive trophic level index TLI (∑) and trophic level index TLI were used to evaluate and analyze the eutrophication of 10 drinking water sources in villages and towns in Dongpo District.The result showed that one reservoir was at medium eutrophication level,the other 9 reservoirs were mildly eutrophic.The eutrophication degree of all reservoirs was lowest in dry season.The water quality of the 10 reservoirs was inferior to the third class of " surface water environmental quality standard" (GB3838-2002).The main pollution factors of water quality and cause eutrophication were TN,the main pollution sources were agricultural non-point source and domestic pollution.关键词
