| 摘 要： | 对长春市南湖水体富营养化状态进行评价，结果为: 一年中有6 个月湖泊处于中营养状态，有 5 个月处于轻度富营养。在10 月份，湖水的TLI 出现了峰值，高达63. 01。分析南湖水体富营养化状态的影响因素，得出结果为: 在温度与光照、物理化学作用及生物化学作用的共同影响下，春季和秋季水体中TLI 值较高，风险较大，而水体富营养化风险最高点出现在秋季，在藻类浓度最高的7 月份需要强化防治措施，避免秋季发生水华现象。

| Abstract: | 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． |
