- Recently much effort has been spend on the evaluation of soil carbon sequestration potential as a measure to temporarily reduce the increasing rate of atmospheric GHGs. 近年来有许多研究致力于探讨土壤碳封存能力,期望能减缓大气温室气体增加的速度。
- Correlation analysis revealed that CPMI may be a better indicator than soil organic matter employed to reflect the dynamic changes of soil nutrients and soil carbon. 相关性分析表明,运用土壤碳库管理指数表征土壤养份及碳素动态变化比土壤有机碳更具灵敏性。

- However, current management of these medium-term leys on many farms would create far more disturbance to their soil carbon store than the 20-year lifecycle of willow coppice or miscanthus. 然而,在许多农场,对这些中期草地的现行管理方式对它们的土壤碳储量所产生的骚扰将远远超过柳树类萌生林或禾本科属的二十年生命周期。
- In addition, soil carbon sequestration effects of conservational farming systems were primarily assessed based on the change of the farming system in the past 20 years in this region. 依据该区近20多年来耕作制度演变动态,对保护性耕作制度的土壤碳收集效应进行了初步估算。
- The available literature suggests that no consistent pattern exists on the impacts of exotic plant invasions on soil microbes, soil animals, soil carbon cycling and nitrogen cycling. 已有的研究表明, 植物入侵对土壤生物多样性及相关生态系统过程的影响均存在不一致的格局, 影响机制也是复杂多样的。
