Analysis of Water Quality Variation Trend and Influencing Factors in South Tai Lake
With the measured data at the base, COD, NH3-N, TP, TN and Chlorophyll A as the analysis objects, the paper has analyzed its change tendency and influencing factors of water quality in south Tai Lake during 2000-2008 years. The main results are as following: (l)Its water quality is stable basically and displays a change tendency with middle high, low both sides in south Tai Lake during 2000-2008. Water quality change tendency is basically same to Tai Lakes; (2)Each water quality index present for the better tendency from north to south, but the density of Chlorophyll A goes up overall; (3) The primary cause, leading to worse water quality in northen part of south Tai lake, is the low quality of water entering the lake. The paper suggests that in order to better water quality in south Tai lake, we strengthen basin pollution government, control pollutant density to enter the lake, optimize basin water resources dispatch and improve basin structure.
