| 摘要: |
| 2004年12月-2005年5月武汉市月湖水生植被重建过程中, 对浮游植物进行逐月调查。结果表明, 在营养盐浓度较高的条件下, 浮游植物仍保持较低的生物量和密度, 浮游植物的生长与温度保持一定的相关性, 但与湖水营养盐浓度并不存在相关关系。菹草和伊乐藻能使水体的透明度保持较高的状态。浮游植物主要由隐藻和硅藻组成, 能形成水华的一些常见种类并未随温度升高而出现, 可能与这两种沉水植物的存在改变了浮游植物的群落结构有关。因此, 在水温较低的冬季和春季进行水生植被重建是富营养化湖泊治理的有效途径。 |

| Abstract: |
| From December, 2004 to May, 2005 phytoplankton was investigated monthly in the process of the aquatic vegetation rehabilitation in Lake Yuehu, Wuhan. The result indicated that, under the condition of high nutrition concentrations, phytoplankton was still maintained at low biomass and density; phytoplankton growth was positively correlated with the temperature, but not with nutrient concentrations. Potamogeion cripus and Elodea canadensis made water body maintain higher transparency. Phytoplankton was mainly composed of cryptophyta and diatom. The typical species of water bloom didnt appear with the increase of temperature. The phytoplankton community structure was possibly changed by existence of these two submerged macrophytes. Therefore, rehabilitation of aquatic vegetation was the effective way to control the eutrophication of the lake in winter and spring of lower temperature. |
