| 中文摘要 | 蓝藻是生物土壤结皮的重要组成部分,具有许多重要的生态功能。迄今为止,黄土高原地区生物结皮中藻类的种类组成及分布鲜有报道。通过野外调查、采样和室内观察、培养、鉴定,对黄土高原水蚀区、水蚀风蚀交错区、风蚀区的生物结皮中蓝藻的多样性及优势种进行了研究。结果表明,黄土高原3个侵蚀类型区生物结皮中蓝藻门植物共发现4科10属54种,其中丝状种类约占87%,占绝对优势;Shannon-Weiner多样性指数水蚀风蚀交错区最高,水蚀区次之,风蚀区最低,依次为2.22,2.20和2.14。水蚀风蚀交错区和水蚀区蓝藻多样性指数差异不显著,但均与风蚀区差异显著。3个侵蚀类型区的生物结皮中蓝藻的种类组成及优势种均有所差异,但均以颤藻科(Oscillatoriaceae)为优势科。水蚀风蚀交错区蓝藻种类最多(39种),以阿氏鞘丝藻(Lyngbya allorgei)为第一优势种;水蚀区次之(26种),以含钙席藻(Phormidium calciola)为第一优势种;风蚀区最少(20种),以颗粒颤藻(Oscillatoria granulata)为第一优势种。黄土高原不同侵蚀类型区生物结皮中蓝藻的多样性差异可能与... 更多 |
| 英文摘要 | Cyanobacteria were the major components in biological soil crusts ( biocrusts) ． So far，studies on species composition and distribution of cyanobacteria in the biocrusts in the Loess Plateau region were fresh． Biocrusts from the revegetated grasslands in different erosion regions ( wind erosion，water erosion，and the wind-water crisscross regions) of the Loess Plateau region were collected，cultured，observed and identified． Results showed that cyanobacteria were the dominant component of the biocrusts． We found 54 species belonging to 10 genera and 4 families，with filamentous cyanobacteria dominant． The Shannon-Wiener index was used to evaluate diversity of the regions． No significant difference was found between the species diversity of water-wind erosion crisscross region and water erosion regions，while diversity in the wind erosion region was significantly lower than the water erosion region or the wind-water crisscross erosion region．Species composition and dominant species of the three erosion regions were different． Oscillatoriaceae was the dominant family from all the three regions． Cyanobacteria species diversity was greatest ( 39) in the water-wind erosion crisscross region，followed by the water erosion region ( 26) and the wind erosion region ( 20) ． However，the dominant species were different in the three erosion regions． The dominant cyanobacteria species in water-wind erosion crisscross region，water erosion and wind erosion region were Lyngbya allorgei，Phormidium calciola and Oscillatoria granulate，respectively． Differences in cyanobacteria composition in the three different erosion regions were likely associated with differences in soil texture，soil pH and climatic regimes． |
