1 GLOBAL GEOLOGY Vol. 32 No. 3 Sept : 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 : 长春南湖 ; 风险 ; 富营养化 ; 评价 : X524 : A doi: /j. issn Evaluation and analysis of eutrophication of South Lake in Changchun WANG Hong-zhe 1 FU Xin-ting 1 HUANG Ji-guo 2 PENG Ju-wei 1 LIU Ning 3 1. Key Laboratory of Songliao Aquatic Environment Jilin Architectural and Civil Engineering Institute Ministry of Education Changchun China 2.

Municipal Engineering Design & Research Institute of Northeast China Changchun China 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 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.
