德国柏林自由大学生物研究所Matthias C. Rillig研究组阐明了多种变化因素，在驱动土壤功能和微生物多样性方面的作用。 相关论文2019年11月15日发表在国际学术期刊《科学》。

研究人员通过实验表明，同时改变全局变化因子（最多10个）的数量会导致土壤性质、土壤作用和微生物群落的方向性变化增加，尽管预测变化的幅度存在较大的不确定性。该研究提供了一个有效的、广泛适用的解决多因素变化的实验设计方案，便于研究全球环境变化的影响。

据了解，土壤是陆地生态系统发挥功能的基础，但它们也面临着许多人为压力。尽管它们具有至关重要的生态作用，但我们对土壤如何一次应对两种以上环境因素知之甚少。

Abstract: Soils underpin terrestrial ecosystem functions, but they face numerous anthropogenic pressures. Despite their crucial ecological role, we know little about how soils react to more than two environmental factors at a time. Here, we show experimentally that increasing the number of simultaneous global change factors (up to 10) caused increasing directional changes in soil properties, soil processes, and microbial communities, though there was greater uncertainty in predicting the magnitude of change. Our study provides a blueprint for addressing multifactor change with an efficient, broadly applicable experimental design for studying the impacts of global environmental change.
