Abstract

According to the relationship between water quality parameters and trophic state index, as well as on the basis of the dividing lakes and reservoirs into four regions, the regional differences of water quality parameters is analyzed by using ArcGIS software, and the parameters include total nitrogen concentration, total phosphorus concentration, chlorophyll a concentration and Secchi disk depth. Then the trophic states of Laoshan Reservoir and Jihongtan reservoir in same region, Nansi Lake and Dongping Lake in different regions were compared and analyzed respectively. The results show that: the trophic states of lakes and reservoirs in the mountainous are better than that of those in the plain; the pollution situation is more serious and the trophic states are worse in industrial areas and populated area.
