April 2009 - March 2010, with the observation in vivo and protein silver staining of Gansu Gannan plateau wetland classification and species diversity in spring ciliates were studied. To 114 kinds of ciliates were identified, belonging to 12 orders, 3 classes, 50 genera and 32 families, including 17 unnamed species and 15 new records of domestic ciliates. Terrestrial-type species, 10 species of aquatic species, 16 species type, surface symbiotic species have 88 kinds, amphibious symbiotic ciliate species similarity 0.7719. Ciliate species on the distribution of each sample results show Rima Man No. 1 (MRM1) the number of sample points ciliates most abundant species, there are 55 kinds; Man Rima 2 (MRM2) samples, followed by There are 53 kinds, Nima (NM), mining Rima (CRM), Azi (AZ) and Mother Mary Monastery (NMS) samples in the number of species were 52,48,38,31 ciliate species, including Mother musjid samples in the least number of ciliate species, only 31 kinds; according to species at various points, the frequency division, distribution frequencies between 0.83 to a widely distributed species, 11 species, distributed in frequency from 0.5 to 0.67 There are 38 kinds of common species, the distribution frequency of 0.17 to 0.33 with 64 kinds of rare species; various species similarity coefficient between points were between 0.1695 ~ 0.3846, showing various points in the distribution of species are not similar; ciliates density and diversity index reflects the various points are very good distribution of the difference between the ciliates. Samples ciliate community environmental factors and structural parameters of binary variables using SPSS13.0 software for the Pearson correlation analysis showed: ciliate species number, density, and soil temperature, pH had no significant correlation between sex (p gt; 0.05), but not with soil moisture was a significant positive correlation (p lt; 0.05), correlation coefficients were 0.858 and 0.822; ciliate species diversity index and altitude have a significant negative correlation (p lt; 0.01), correlation coefficient -0.889; ciliates density altitude was a significant negative correlation (p lt; 0.01), correlation coefficient of -0.824. Correlation coefficient based on the size seen in the various environmental factors, the greatest impact on the number of species of ciliates is moisture. The greatest impact on ciliates density is elevation, followed by soil water content. From the analysis of community structure, moving substrate Gang (Kinetofragminophorea) the largest number of species, 6 orders, 15 families, 24 genera and 57 species were identified from ciliates accounted for 50% of total; multi-film Gang (Polyhymenophorea), followed by 3 orders 10 families and 18 genera and 37 species of ciliates identified accounted for 32.46% of the total; widowed film Gang (Oligohymenophorea) species at least, only three orders, 7 families 7 genera and 20 species, accounting for the total number of identified 17.54% of the ciliates. Gansu Gannan plateau wetland soil specific groups still dominate, the former mouth mesh (Prostomatida), under the hair mesh (Hypotrichida) and kidney-shaped head (Colpodida) ciliate species number far greater than other groups, which in addition to the parasite itself adaptive features, with the region's habitat types are compatible, because the region despite the wetland areas are, but its decision to the local climatic conditions of the points just winter without significant seasons, and more precipitation The summer climate is relatively short, longer periods of drought in winter, so most of the year in the region is not a lot of water, most of the marsh during times of drought have formed a meadow, and therefore more suitable habitat distribution in the soil more fiber caterpillar species. Of course, the region has its wetland characteristics, compared with other arid environments have a more adequate moisture, therefore, the region also appeared such as bags shaped head (Bursariomorphida), suction head (Suctorida) and ciliate mesh (Peritrichida) and some other aquatic , a large species of ciliates, which also fully verify the specificity of wetlands, namely land and water with transitional, both land and water features in common.
