According to the messurement of the root biomass of Si Chuan Qi Mu plantation in Xiang Bei distract, Research the distribution of different drive-lever root biomass,Analised the characteristic of each space of boot drive-lever's root length,than the root length ,root length density.The result shows that :1.The big root , middle root, small root,fine root biomass of Si Chuan Qi Mu plantation accounted for stand root sum total fifty five persent ,twenty two persent,nine persent. About sixty six persent root biomass focus in 0~30cm soil, This prove that Qi Mu was the shallow root trees.2.Every drive-lever root length trend in Si Chuan Qi Mu plantation is fine root than small root than big root than middle root .Than root length 's change is :fine root than small root than middle root than big root .3.Every drive-lever root biomass's root length density distribution in Si Chuan Qi Mu plantation is different. 收起
