| 摘 要： | 在生物量的研究过程中,地下部分生物量十分重要却又多被忽视本文首先比较了当前地下生物量研究中较为常用的4种研究方法:挖土块法、钻土芯法、内生长土芯法和微根区管法.然后总结了地下生物量在空间和时间上变化规律的研究成果.最后又讨论了环境因素诸如水分、温度和开垦、放牧对地下生物量的影响以及地下生物量的周转.

| Abstract: | In the process of biomass study,underground biomass was very important,but it was often ignored.In this paper,were the four main methods used in studying:soil monolith,soil coring,ingrowth soil core,and minirhizotron.And then,we concluded the rule of underground biomass changing in space and time.We also discussed the effect of environmental factors on underground biomass such as precipitation,heat, reclamation,grazing and the turnover of underground biomass. |

| Keywords: | Underground biomass Turnover rate |
