According to the evaluation of eutrophication of the South Lake in Changchun, the Lake is mesotrophic for 6 months in a year and slightly eutrophic for 5 months. In October, TLI of the Lake reaches its peak, up to 63.01. By analyzing the contributing factors of eutrophication, we know that under the joint effect of temperature and illumination, physicochemical action and biochemical action, TLI value is higher in spring and autumn time, with a higher risk. The highest point of risk of eutrophication occurs in autumn time. In July when the alga concentration is the highest, preventive measures should be reinforced to prevent water bloom in autumn.
