研究土壤中细菌与土壤跨尺度耦合动力学，因土壤特性及细菌与环境双向反馈使理解困难，通过综述探讨其在单孔隙、多孔隙中尺度和更广阔区域三个尺度上对细菌运动、生长和感知物理过程的支配作用。

土壤中蕴含着地球上大部分细菌生命。这些细菌的活动控制着植物生长、碳氮循环以及土地对气候变化的响应。然而，理解这种活动颇具困难，因为土壤在结构和化学上具有异质性且光学不透明，细菌不仅对周围环境做出反应，还不断重塑环境，这种双向反馈常被理想化实验和理论忽略。本文综述了这种动态反馈如何在单孔隙、多孔隙中尺度和更广阔区域这三个尺度上支配土壤中细菌运动、生长和感知的物理过程。
英文摘要
Soil harbors much of Earth's bacterial life. The activity of these bacteria governs plant growth, carbon and nitrogen cycling, and the response of land to a changing climate. Understanding this activity is difficult, however: soil is structurally and chemically heterogeneous and optically opaque, and its bacteria not only respond to their surroundings but continually reshape them, a two-way feedback that most idealized experiments and theories overlook. Here we review how this dynamic feedback governs the physics of bacterial motility, growth, and sensing in soil across three scales -- the single pore, the mesoscale of many pores, and the broader landscape.
