This paper investigated spatial distribution of Zanthoxylum bungeanum fine roots,which were sampled by excavating *** results showed that the root length density,surface area,volume as well as biomass were decreased with an increase in depth from 20 cm to 100 *** roots mainly distributed in 0~40 cm in the verticality,and the root length density,surface area,volume as well as biomass amounted to 72.0%,65.6%,59.2% and 57.5% of the corresponding total *** and maximum of specific root length were respectively exhibited at 0~10 cm and 70~80 cm in the *** addition,the root horizontal distribution reached to 110 cm,however most fine roots distributed within 50 cm and the *** the root length density and biomass accounted for 71.5% and 76.4% of the total amount *** minimum and the maximum of specific root length were exhibited at 10~20 cm and 70~80 cm in the horizon.
