The distribution of cellulose–decomposed actinomycetes was studied by conventional methods. Those microbes were separated in soil from the eastern part of Qinghai Plateau. The results indicated that: There were a certain amounts of cellulose-decomposed actinomycetes in soil from the eastern part of Qinghai Plateau. The number of cellulose-decomposed actinomycetes in vegetable field soil was higher than in grain field, but the strong cellulose-decomposed actinomycetes’ ratio of cellulose-decomposed actinomycetes in vegetable field soil was lower than that in grain field. The strong cellulose-decomposed actinomycetes’ ratio of the total cellulose-decomposed actinomycetes in natural soil had certain relevance with the soil organic matter content. In each kind of natural soil, the number of cellulose-decomposed actinomycetes in cumulated irrigated soil was the maximum, and the number of strong cellulose-decomposed actinomycete in castanozem was the most, and the strong cellulose-decomposed actinomycetes’ ratio of cellulose-decomposed actinomycete in marsh soil was the highest. The results may provide scientific basis for separation and screening of the cellulose–decomposed actinomycetes
