| 摘 要： | 通过野外采样,室内培养、观察、鉴定,研究了沙坡头地区藻类多样性和分布特点,并为当地藻类资源利用提出建议。研究发现沙坡头地区藻类植物共计40种(包括1变型),其中蓝藻17种,绿藻10种,硅藻9种,裸藻4种,全为普生种,陆地生境中种类最丰富。亚气及陆地生境中蓝藻在种类数(除灌溉林地结皮)、生物量方面占主导地位;贫瘠水体生境中硅藻占主要地位,营养较丰富水体中绿藻处于优势地位。另外,陆生生境中多以具鞘微鞘藻Microcoleus vaginatus为优势种,小席藻Phormidium tenue为主要种。

| Abstract: | A total of 40 algal taxa (including 1 variety) was collected and identified in this work. Seventeen of these were blue - green algae, 10 were green algae, 9 were diatoms, and 4 were euglenoids, and they were all common species. Of which terrestrial inhabitats were most abundant. Cyanobacteria dominated in subaerial and soil inhabitats in terms of number of species or in biomass, while diatoms and green algae have advantages in oligotrophic and mesotrophic aquatic environments respectively. Some suggestions about the potential application of these species had been given. |
