摘    要:2009年6—9月份对扎龙湿地具有代表性的典型区域进行了浮游植物调查,共发现浮游植物243个分类单位,分别隶属于8门、12纲、22目、38科、82属、243种。初步分析了扎龙湿地夏秋两季典型区域浮游植物群落的种类组成,结果表明:种类组成最多的为硅藻门,共90个分类单位,占37.04%,其次为绿藻门88个分类单位,占36.21%;数量组成也以硅藻门最多,为14.51×104个.L-1,占总数量的50.33%,绿藻门次之,为6.54×104个.L-1,占22.69%。根据种类组成及分布初步推断,扎龙湿地浮游植物夏季为硅藻—绿藻优势型;秋季为硅藻—绿藻—裸藻优势型。夏季优势种为梅尼小环藻(Cyclotella meneghiniana Kutz.)和华丽星杆藻(Asterionella formosaHass.);秋季优势种为颗粒直链藻(Melosira granulata(Ehr.)Ralfs)和梅尼小环藻(Cyclotella meneghiniana Kutz.)。扎龙湿地总体处于贫中营养状态。

关 键 词:扎龙湿地  浮游植物  群落结构

Abstract:An investigation on phytoplankton was carried out in Zhalong wetland in June and September 2009 by setting up 23 systematically placed sample stations.A total of 243 taxa were identified,belonging to 8 phyla,12 classes,22 orders,38 families,82 genera and 243 species.Phytoplankton community composition was analyzed,which consisted of 90 Bacillariophyta(37.04%) and 88 Chlorophyta(36.21%).Phytoplankton community biomass was also determined,of which Bacillariophyta accounted for 14.51×104 ind·L-1(50.33%) and Chlorophyta for 6.54×104 ind·L-1(22.69%).Based on species composition and distribution in Zhalong wetland,the community composition of algae could be classified as Bacillariophyta-Chlorophyta type in summer and Bacillariophyta-Chlorophyta-Euglenophyta type in fall.The survey shows that Cyclotella meneghiniana Kutz.and Asterionella formosa Hass.are dominant taxa in summer.Melosira granulata(Ehr.) Ralfs and Cyclotella meneghiniana Kutz.are dominant taxa in fall.In trophic status,oligosaprobic to mesosaprobic varieties are dominated in Zhalong wetland.
Keywords:Zhalong wetland  Phytoplankton  Community structure
