Abstract In order to clarify the biological characteristics of peat moss from different areas，we compared and analyzed 8 bacterial diversities of KLASMANN（Germany），TERRACULT（Germany），PINDSTRUP（Denmark），KEKKILA（Finland），QINGYUAN（Liaoning），LIAOYUAN（Jilin），HUACHUAN（Heilongjiang）and YANSHOU（Heilongjiang）with PCR-DGGE method．The highest number of bands in LIAOYUAN，HUACHUAN and YANSHOU was 24，and the lowest number of bands in PINDSTRUP was 19．The differences between them were significant．The highest evenness index was YANSHOU，the lowest was KEKKILA．The differences between them were significant．The highest and lowest diversity indexes were QINGYUAN and KLASMANN，respectively．The highest similarity coefficient among the group was 72.9%，found between HUACHUAN and YANSHOU，while the lowest was 55.6%，found in KEKKILA and HUACHUAN．All these results indicated that there were differences in quantities and species of bacteria among peat-mosses from different areas．
