Therefore, lake sediments have recorded eutrophication process of Lake Dianchi from oligotrophic lake to eutrophic lake. Especially in the past several decades, both autochthonous and allochthonous organic matter display rapid increasing. Combined with isotopic data, a conclusion is drawn that Lake Dianchi has entered into a hypereutrophic stage.

因此，湖泊沉积物记录了滇池从一个贫营养的湖泊演变成富营养化湖泊的过程，特别是最近几十年，滇池内源有机物和陆源有机物的输入都呈现快速增长的趋势，结合同位素组成特征表明滇池进入了重富营养化阶段。

The activitys of Super Oxide Dismutase, peroxidase and Multiple Displacement Amplification of Ceratophyllum demersum L raised rapidly in the late of experiment, and the maximum value of MDA of Ceratophyllum demersum L in the eutrophic condition was 5 time higher than that in the medium nutritional condition, implied that Ceratophyllum demersum L has been stressed in the middle nutritional condition.

金鱼藻超氧歧化酶活性、过氧化物酶活性和丙二醛含量在试验后期上升速度加快，且富营养水平下金鱼藻MDA质量分数的最大值是中营养水平下最大值的5倍，表明在中营养水平下金鱼藻已经受到明显胁迫，而在富营养水平下受到胁迫更为显著。

The results showed that during the 45 days experimental time the fresh weigh of Myriophyllum spicatum L, Hydrilla verticillata L and Cerato-phyllum demersum L were 0.92 g, 0.27 g, 1.11 g and 0.56 g, 0.41 g, 0.87 g in medium nutritional condition TN 1.86 mgL^(-1; TP0.087 mgL^(-1) and eutrophic condition TN 2.47 mgL^(-1; TP0.16 mgL^(-1), respectively. The largest single plant biomass of Myrio-phyllum spicatum L and Ceratophyllum demersum L in in middle nutritional condition were over 39% and 22% higher than those in eutrophicated condition, but that of Hydrilla verticillata L was less than 51%, which shown that Myriophyllum spicatum L and Ceratophyllum demersum L grow better than Hydrilla verticillata L in middle nutritional condition.

研究结果表明，在45 d的培养过程中，狐尾藻、轮叶黑藻和金鱼藻在中营养TN1.86 mgL^(-1； TP0.087 mgL^(-1)和富营养TN2.47 mgL^(-1； TP0.16 mgL^(-1)水平下的单株最大生物量分别是0.92、0.27、1.11、0.56、0.41和0.87 g，狐尾藻和金鱼藻在中营养水平下单株最大生物量分别较富营养水平下高出39%和22%，而黑藻在中营养水平下单株最大生物量较富营养水平下低了51%，表明狐尾藻和金鱼藻在中营养水平下的生长较黑藻好。

The removal efficiency of nitrogen and phosphorus in eutrophic lake water by attached Cladophora oligoclona has been investigated at the conditions in laboratory and outdoor, respectively.
