甘肃白水江国家级自然保护区土壤肉鞭虫物种多样性

2004年2月～2006年5月,用"非淹没培养皿法"和活体观察法对甘肃白水江国家级自然保护区土壤肉鞭虫的物种多样性进行了研究。共鉴定到肉鞭类原生动物84种,其中包括2个未定名种和23个国内土壤肉鞭虫新纪录种,隶属于2亚门5纲13目32科49属。鞭毛亚门以动基体目的物种占优势,肉足亚门以变形目的物种占优势。研究结果表明,保护区土壤肉鞭虫物种丰富,特有和稀有物种较多,物种组成具有独特性。分析了保护区土壤肉鞭虫物种多样性与自然环境的关系。

Specific Diversity of Soil Amoebae and Flagellates in the National Nature Reserve of Baishuijiang, Gansu

Specific diversity of soil amoebae and flagellates in the National Nature Reserve of Baishuijiang,Gansu was studied based on the "non-flooded petri dish method"and the observation in vivo from February 2004 to May 2006.A total of 84 species,including 2 unknown species and 23 new records of soil amoebae and flagellates in China,belonging to 2 subphylums,5 classes,13 orders,32 families and 49 genera,were identified.The number of species of Kinetoplastida and Amoebida occupied a dominant position respectively in Mastigophora and Sarcodina.The result of the study showed that:1) there were rich species and endemic and rare species of soil amoebae and flagellates in the National Nature Reserve;2) the species composition of soil amoebae and flagellates in the National Nature Reserve was unique.The relationship between the specific diversity of soil amoebae and flagellates and the natural environment in the National Nature Reserve of Baishuijiang was analyzed briefly.
