| 摘要: |
| 为研究黑龙江扎龙湿地不同功能区浮游植物群落结构分布及其与环境因子的关系,于2010年78月在扎龙湿地4个功能区340个研究点进行水环境样品采集分析.样品共鉴定出浮游植物6门80属354种,各门类细胞密度变化范围为0.06×106~37.82×106 cells/L.主要优势种为普通小球藻(Chlorella vulgaris)、梅尼小环藻(Cyclotella meneghiniana)、旋转囊裸藻(Trachelomonas volvocina)等.各功能区浮游植物优势种差异较大,核心区中放射舟形藻(Navicula radiosa)、弯棒杆藻(Rhopalodia gibba)、扁圆卵形藻(Cocconeis placentula)等为优势种类,而排污区中梅尼小环藻、普通小球藻、巨颤藻(Oscillatoria princes)、固氮鱼腥藻(Anabaena azotica)等处于优势地位.主成分分析表明在扎龙湿地水环境中浊度和总磷浓度是影响浮游植物生长的主要因素,典范对应分析结果表明总氮浓度、总磷浓度、电导率、浊度对浮游植物属种分布影响较大,梅尼小环藻、箱形桥弯藻(Cymbella cistula)、美丽星杆藻(Asterionella formosa)、普通小球藻、旋转囊裸藻等受环境因子的影响较为明显. |

| Abstract: |
| Samples were carried out at 340 sites of four functional areas in Zhalong Wetland during July and August 2010 in order to study the structure of phytoplankton community and its relationship with environment factors. Totally 6 phylum, 80 genera and 354 species of phytoplankton were identified. The phytoplankton abundance ranged from 0.06×106 to 37.82×106 cells/L. The dominant species were Chlorella vulgaris, Cyclotella meneghiniana and Trachelomonas volvocina. The phytoplankton community structures in different functional regions were different. In the core region, the dominant species were Navicula radiosa, Cocconeis placentula and Rhopalodia gibba, while Oscillatoria princes and Anabaena azotica were dominant species in the discharge region. Principal components analysis indicated that turbidity and total phosphorus in the water environment were main factors effecting the growth of phytoplankton in Zhalong Wetland. Canonical correspondence analysis illuminated total nitrogen, total phosphorus, turbidity and conductivity could be the main forces structuring on the phytoplankton community in Zhalong Wetland. Cymbella cistula, Asterionella formosa, Chlorella vulgaris and Trachelomonas volvocina were affected greatly by physicochemical factors. |
