Collembola sampling was carried out in buffer area of Xuan Son National Park (NP), Phu Tho (including 7 village Kim Thuong, Xuan Dai, Minh Dai, Tan Son, Kiet Son, Lai Dong, Dong Son) with 8 fieldtrips during the period 2009-2011. According to 5 habitat types: Natural forest, plantation forest, cultivated land with polyannual fruit-tree, agricultural land with annual plants and tee-growing land. Totally, 380 soil samples were obtained and invesgated. Berlese-Tullgren funnels were used for extraction of soil collembola from the collected materials. The samling and extraction methods are described in details in Ghilarov (1975) and Krivolutsky (1975). Data were analysed and calculated after to Gormy and Grum (1993). In general, the results analysis have showed that there is a significant relation between the qualitative, quantitative structure of collembola and habitat types. The species number, H' diversity index, J' green index, and the propotion of litter-groups gradually decreased from natural forest to cultivated land with polyannual fruit-tree, agricultural land with annuaal plants and tee-growing land, the density and the propotion of soil-groups of collembola community gradually increased. The research .results showed that the habitat types have influence in changing the dominant species. The dominant structure of collembola in 5 study habitat indicated the quality of forest soil better than of cultivated land and agricultural land.
