Three transformation modes were used to improve the lowefficiency Cupressus funebris stands in Jingyang of Deyang City, Sichuan Province in 2002. The three transformation modes included C. funebris+Alnus cremastogyne+Bambusa pervariabilis×Dendrocalamopsis daii mode (BZQ), C. funebris+Quercus acutissima mode (BL), and C. funebris+B. pervariabilis×D. daii mode (BZ). After eight years of transformation, we investigated the fine root biomass of differently transformed Cuprssus funebris stands in the soil profiles. The results showed that the transformation modes and soil layer affected the fine root biomass significantly (P<0.01). Fine root biomass of BZ and BZQ were significantly higher than that of CB, while the fine root biomass of BL was the lowest. The fine root biomass of C. funebris distributed differently among the different transformation modes, increasing with the increase of soil depth in BZ and BZQ, while decreasing in BL. The proportion of C. funebris dead fine roots in BL was significantly higher than that in the other transformation modes. The distribution of fine root biomass was relatively stable in BZQ, while was poorly stable in BL.
