蓝藻植物

The phytoplankton community was mainly composed of Cyanophyceae, Euglenophyceae, Bacillariophyceae, and Chlorophyceae, and the dominant species were Oscillatoria subtillissima, Dactylococcopsis irregularis, Euglena caudata, Melosira granulata, Cyclotella meneghiniana, Chlorella vulgaris, and Scenedesmus quadricauda. The main environmental factors affecting the distribution of phytoplankton species in July were ammonium-nitrogen, dissolved oxygen, water temperature, and total phosphorus, while those in September were pH, water temperature, dissolved oxygen, transparency, and total nitrogen. Water transparency and zooplankton were the main factors affecting the biomass of Cryptophyceae, Pyrrophyceae, and Bacillariophyceae; while nitrogen, phosphorous, and dissolved oxygen were the main factors affecting the biomass of Cyanophyceae, Euglenophyceae, and Chlorophyceae.

结果表明：调查期间共鉴定出浮游植物384种，隶属于8门，浮游植物密度范围为2.01×105～57.60×105 cells·L-1；群落组成以蓝藻、裸藻、硅藻和绿藻为主，主要优势种有细微颤藻、无常蓝纤维藻、尾裸藻、颗粒直链藻、梅尼小环藻、普通小球藻、四尾栅藻等；7月影响浮游植物分布的主要环境因子依次为铵态氮、溶解氧、水温和总磷，而9月的pH值、水温、溶解氧、透明度和总氮含量对浮游植物的分布产生影响较大；其中，透明度和浮游动物量是影响隐藻、甲藻和硅藻藻类生物量的主要环境因子，而蓝藻、裸藻、绿藻主要受水体氮磷营养盐浓度和溶解氧的影响。

In total, 5 phyla, including 72 genera and 177 species were identified, of which chain\|shaped ones were dominant, in which diatoms dominated, and dinoflagellates went the second place.

共鉴定出浮游植物5门72属177种，浮游植物以硅藻为主，但甲藻在群落中的比重也很明显，此外还有少量的绿藻、蓝藻和金藻。

Of the total 262 species found in this area, 82 occurred in spring, 117 in summer, 119 in autumn, and 141 in winter. Taxonomically, 252 species in 67 genera were Bacillariophyta, 8 species 5 genera were Pyrrophyta and 2 species 1 genus were Cyanophyta.

中文摘要：2006 年8 月—2007 年4 月对广东省徐闻珊瑚礁区的浮游植物进行了周年的季节调查，结果共检出浮游植物262 种：春季82 种、夏季117 种、秋季119 种、冬季141 种，其中硅藻门67 属252 种，甲藻门5 属8种，蓝藻门1 属2 种。

Results show that there are 73 species,62 genus,8 phylum phytoplankton,which is mainly composed of the Chlorophyta ,Bacillariophyta and Cyanophyta.

2005年12月和2006年6月对苏州平原河网区57个浅水湖泊的浮游植物群落进行了调查，共检出浮游植物8门62属73种，浮游植物主要由绿藻、硅藻和蓝藻组成。

Compared to CK, the rice-fish ecological system increased its density and biomass, decreased the predominance of Bacillariophyta and Cyanophyta, and increased the diversity index.

稻鱼共作显著增加稻田水体浮游植物的密度和生物量，降低硅藻和蓝藻的优势度，增加绿藻和裸藻的优势度，提高了稻田水体浮游植物多样性指数。

During the study period, the total of the phytoplankton species discovered was seven phylum,58 category and 183 kinds. Most of them belong to Cyanophyta, Bacillariophyta and Chlorophyta.

浮游植物种类组成显示，整个研究期间共发现7门58属183种，与蓝藻门、硅藻门和绿藻门为主。

Totally, 93 taxon belonging to 4 phyla were observed, among them, 68 taxon in 35 genera belonged to Bacillariophyta, 21 taxon in 11 genera for Dinophyta, 2 taxon in 1 genus for Cyanophyta and 2 taxon in 1 genus for Chrysophyta.

共鉴定浮游植物93种，其中硅藻35属68种，甲藻11属21种，蓝藻1属2种以及金藻1属2种。

Wanfenghu reservoir has been polluted seriously, and waters are in a severe eutrophication condition. Whether physico-chemical indexes or biological indexes appraisal, it proved that the water quality of Wanfenghu is between IV-V. Wanfenghu contains high TN and TP which are 5 to 6 times of the national standard content, and the quantities construction of phytoplankton communities is deeply disequilibrium, the Cyanophyta and Charophyta occupying overwhelming

万峰湖水库已经受到了严重污染，水体处于严重富营养化状态，其水体中的溶解氧的三季变化范围在2.92-5.3mg·L之间、化学耗氧量三季平均值为34.77 mg·L~(-1)、总氮三季平均值为2.5 mg·L~(-1)、总磷的三季平均值为0.35 mg·L~(-1)、叶绿素a含量的三季平均值为23.64 mg·m~(-3)，以上各指标表明万峰湖水库水体处于Ⅳ-Ⅴ类水质；无论从浮游植物的群落数量上还是浮游植物种类组成上看，蓝藻和绿藻都占绝对优势，而其它各种藻类极少，是典型的蓝-绿藻型水

They also showed that large Cladocera size is more important than their number for efficient phytoplankton control and when cladocerans are large enough, they can considerably restrain phytoplankton growth, including bloom-forming cyanobacteria, even when submerged vegetation is not restored.

同样，它们也显示了大型枝角类的体型相对于它们的数量就对浮游植物的有效控制上意义更大。当枝角类足够大时，它们能够限制浮游植物的生长，包括蓝藻的爆发，即便当沉水植被没有及时恢复。

In March, May and July, Cyanophyta was the dominant one, with high proportions of 45.6%, 55.9% and 87.7%, respectively, whereas the proportions for Bacillariophyta decreased to 30.1%, 25.9%, and 1.1%, respectively. In November, proportions for Bacillariophyta and Chlorophyta were equivalent, 40% each, and the Cyanophyta composed below 20%. In December, Bacillariophyta made up 25.6% and Cyanophyta 38.2%. In March, May and July, dominant species of Cyanophyta were Microcystis aeruginosa, Pseudoanabaena, and Gloeothece linearis. In dry January, November and December, species of Bacillariophyta were dominated by A chnanthes sp., Melosira ambigua, Melosira granulata and Cyclotella meneghiniana.

全年中，蓝藻与硅藻比例变化较大，二者呈相反的变化趋势。1月份硅藻占较高比例（63.1％），蓝藻较低（〈20％）；3、5、7月份蓝藻比例较高（分别为45.6％、55.9％、87.7％），而硅藻较低（30.1％、25.9％、1.1％）；11月份硅藻与绿藻比例相当（各占40％），蓝藻低于20％；12月份硅藻与蓝藻比例分别为25.6％与38.2％。3月份和丰水期浮游植物优势种主要为铜绿微囊藻、假鱼腥藻和线形粘杆藻等蓝藻种类，枯水期的1月、11月和12月主要以曲壳藻类、模糊直链藻、颗粒直链藻和梅尼小环藻等硅藻种类为优势种。
