%X Soil samples were collected from six kinds of soil in Haibei alpine meadow ecosystem during 2001 - 2002. More than 300 strains of actinomycete were isolated by five agar media. On the basis of morphological characteristics and some chemotaxonomic properties, the isolated strains were classified into different genera, such as Micromonospora, Nocardia, Saccharopolyspora, Promicromonospora, Streptomyces, and the Streptomyces strains were classified into seven groups. The result indicated that the biodiversity of actinomycetes in different soils and the actinomycetes abundance of different kinds showed significant differences. The activities of some enzymes produced by mesophilic and psychrophilic actinomycetes also discussed in this paper. It is found that many strains of streptomyces not only have some enzyme activities such as starch decomposition, nitrate deoxidization, gelatin utilization etc., but also have some inhibiting activities for fungi and bacteria offered to test, whereas the rare actinomyces showed low positive rate of enzyme activities and inhibiting activities for fungi and bacteria.
