摘 要：
利用2010年3月～2011年2月瑶湖水质监测指标的数据,运用Q型聚类分析法将全湖14个数据监测点分成4类区域。在此基础上,选用综合营养状态指数(TLI)法对全湖水体进行了整体和分区段的营养状态评价。结果表明,在时间上,湖区全年整体呈轻度富营养化状态,其中夏、秋两季富营养化程度明显高于冬、春两季;在空间上,湖区水体营养化程度的分布情况为:南部严重,中部过度,北部适度。

摘 要：
According to the data analysis of water quality monitoring indexs in Yao Lake from March 2010 to February 2011,fourteen monitoring points were classified into four kinds of areas with using Q-type clustering analysis method.On the basis of this,the trophic state of lake for whole and section was evaluated by comprehensive eutrophication state index(TLI) method.In time,the whole lake was under light eutropher throughout the year,and the eutrophication degree in summer and autumn was obviously higher than that in winter and spring;in space,the nutritious level distribution of the lake: southern part is serious,middle part is transitional and northern part is moderate.
