用活体观察和固定染色方法对麦积山风景名胜区土壤纤毛虫物种多样性进行了研究。共鉴定到隶属于3纲12目41科55属的土壤纤毛虫115种,其中包括11个未定名种和26个中国土壤纤毛虫新纪录种。街子温泉景区、曲溪景区、麦积山石窟区、石门山和仙人崖景区各分布有47、46、44、33和26种,大弹跳虫、似织毛虫、膨大肾形虫、僧帽肾形虫、迅捷肾形虫、吻四膜虫、长刀口虫和苔藓刀口虫为广布物种。前口目和下毛目为风景名胜区土壤纤毛虫群落中的优势类群,肾形目和盾纤目为次优势类群,侧口目、吸管目和寡毛目为罕见类群。风景名胜区土壤纤毛虫物种多样性与我国已有研究报道的其他地区的均极不相似。研究结果表明,风景名胜区土壤纤毛虫物种十分丰富,特有和稀有物种繁多,群落结构复杂而特殊;土壤和水生纤毛虫群落物种组成极不相似,土壤和水生纤毛虫群落是不同的2个独立群落。
The species diversity of soil ciliates in the Maiji Mountain Scenic Area was studied by in vivo observation and fixed staining. A total of 115 soil ciliates belonging to 55 genera, 41 families, and 12 orders belonging to 3 orders, including 11 unidentified species and 26 new records of soil ciliates in China, were identified. There are 47, 46, 44, 33 and 26 species of Jiezi Hot Spring Scenic Spot, Quxi Scenic Spot, Maiji Mountain Grottoes, Shimenshan Mountain and Fairy Cliff Scenic Spot respectively. The large spring brats, like caterpillars, Rendezvous, Renal fast nematode, Tetrahymena kyphosis, Long-knit moth and moss Knifeworm are widely distributed species. The frontal orders and the lower orders were the dominant groups in the soil ciliates community in the scenic spots, while the nephrites and dodecandrums were the subdominant groups. The species diversity of soil ciliates in the scenic spots is very dissimilar to other areas reported by our country. The results showed that the species of soil ciliates in the scenic spots are very rich, the endemic and rare species are numerous, the community structure is complex and special, the species composition of soil and aquatic ciliates is extremely dissimilar, and the soil and aquatic ciliates community are two different independent communities .
