| 摘 要： | 采用综合营养状态指数TLI(Σ)对"十一五"期间滴水湖富营养化状态、时空分布特征及变化趋势进行了评价及分析。结果表明:滴水湖水质整体处于轻度富营养状态,石皮泐港进水口的综合营养状态指数大于湖区各点位;每年4月-5月和8月-10月两个时间段,滴水湖综合营养状态指数较高;"十一五"期间,滴水湖的富营养化状态呈现不显著下降的趋势。建议加强对水体叶绿素a浓度等生物指标的监测,以更全面地评价滴水湖的营养状态。

| Abstract: | The eutrophication status and variation trend of Dishui Lake during 2006 to 2010 were assessed and analyzed by trophic level index TLI（Σ）.It was found that the water of Dishui Lake was light eutrophic in general,and TLI（Σ） of the influent was higher than that of the lake.The annual maximum values of TLI（Σ） appeared during April to May and August to October.TLI（Σ） seemed to decline slightly during the five years.The concentration of Chlorophyl a was suggested to be monitored regularly to assess the entrophication status of Dishui Lake. |
