According to the evaluation of eutrophication of the South Lake in Changchun��we have known that 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 times 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��
