中文摘要: |
2008年7月至2009年5月对宝应湖浮游植物进行调查。结果显示,宝应湖共有浮游植物62种,隶属8门22科36属,其中绿藻门有14属25种,硅藻门有8属14种,蓝藻门有8属12种。优势种季节性变化明显,全年优势种为小球藻、啮齿隐藻、湖生束球藻等。全年种类结构以绿藻、蓝藻等为主,生物量以蓝藻、绿藻和隐藻为主。不同采样点浮游植物数量在2.94×106~8.08×106ind/L,Shannon-Weaver指数2.040~3.284。宝应湖处于中营养状态向富营养状态过度的类型。 |

An investigation was carried out in Lake Baoying from July 2008 to May 2009.62 species of phytoplanktons was identified. 25 species belong to 14 genera of Chlorophyta. 14 species of Bacillariophyta,and 12 speciessa,Gomphosph belong to 8 genera of Cyanophyta,The dominant species were Chlorella vulgaris, Cryptomonas erosa, Comphosph aeria lacustris. The phytoplankton community structure of Lake Baoying was of green-blue agale type, and biomass of Cyanophyta , Chlorophyta and Cryptophyta was dominant in four seasons. The quantity of phytoplankton in different sample stations ranged from 2. 94 x 106 ind/L to 8.08x106 ind/L. Shannon-Weaver index was 2. 04-3.45. All the features indicate that the lake can be from mesotrophy to eutrophication. |
