我们生活在固体地球和其外部流体包层之间的动态界面上。这一界面从外部植被树冠延伸到活跃的地下水底部，最近被命名为临界区，因为它支持生命，并越来越多地受到人类行动的影响。要了解在临界区内运行和形成临界区的过程之间的复杂相互作用，需要跨越广泛的空间和时间尺度的跨学科方法。构造作用、风化作用、流体运移和生物作用控制着临界区的功能和结构。美国国家科学基金会最近建立的三个临界区观测站旨在整合对过程相互作用的研究，最高可达分水岭尺度。该计划的一个目标是将三个独立构思的天文台建立成一个网络，从中可以产生更广泛的理解、更大的空间尺度以及更深的洞察力。
We live at the dynamic inter-face between the solid Earth and its outer fluid envelopes. This interface, extending from the outer vegetation canopy to the base of active groundwater, was recently named the Critical Zone because it supports life and is increasingly impacted by human actions. Understanding the complex interactions between processes that operate in and shape the Critical Zone requires interdisciplinary approaches that span wide spatial and temporal scales. Tectonic processes, weathering, fluid transport, and biological processes control the function and structure of the Critical Zone. Three Critical Zone Observatories recently established by the U.S. National Science Foundation are designed to integrate studies of process interactions up to the watershed scale. A goal of the program is to build the three independently conceived observatories into a network from which broader understanding larger spatial scales but also deeper insight - can emerge.
