藻类

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。

Among euglenoid species, three nutrition types coexist, the phototrophic, saprophytic and phagotrophic.

裸藻类中并存着光合自养、腐生和吞噬三种不同营养类型。

Then,the methods of algae control in eutrophic lake and the processes of algae removal in the raw water are described.

The composition, distribution, nutritional requirement of soil algae were studied in Feng-qiu Agricultural Experiment Station of CAS.

藻类是分布最广泛、结构最简单的光合生物。

The coefficient of non-algal particulates is decreasing with the increase of wavelength, which can be described by exponential law.

非藻类颗粒物的吸收系数随着波长的增大而减小，可用指数衰减规律来描述；光谱斜率S较离散，但平均值与文献报道的一类水体S的平均值很接近；光谱截距ad0(λ0)随盐度增大而减小，二者有很好的线性关系。

The eyespot of unicellular and colonial algae and their gametes and zoospores contains globules of orange or red carotenoid pigments.

单细胞生物和群体藻类的眼点、配子和孢子含有橙色或红色的类胡萝卜素。

The comparison between the obtained EC50 values and toxicity data from the literature points out the good agreement between the BOD bottle test (Raphidocelis su.) and those of nine widely used test methods, i.e., Fathead minnow, Vibrio fi., Microtox, Polytox, Spriotox, Shk1, Activated sludge, Daphina ma. and Tetrahymena. In this study, log Kow values of narcosis Ι compounds (using the BOD bottle test and nine bioassays) were reported.

实验中选定DO观测终点所求得的毒性数据与其他物种进行回归分析，回归结果则皆呈现高度相关（R2值≧0.84），这可推论出藻类与其他物种的分析方法（不含Nitrosomonas）的致毒机制有很高的相关性，且可知本试验方法不仅敏感性高且与其他的物种且有良好的相关性可做为替代性试验。

They often resemble plants and are found mainly in marine or fresh-water habitats, although some algae are terrestrial.

藻类在自然界几乎到处都有分布，主要是生长在水中，也有陆生的。
