抽象的。陆地表面、水文学和地下水模型团体都具有模拟地球系统陆地部分的水文过程的专业知识。然而，这些社区以及更广泛的地球系统模型界在很大程度上仍然各自为政，各学科之间的合作有限，阻碍了在表示地球系统模型陆地部分的水文过程方面取得进展。为了解决关于未来水资源的可获得性和气候变化中洪水和干旱等极端事件的强度等关键社会问题，这些社区必须走到一起，发挥彼此的优势，产生能够充分模拟变化下的陆地水循环的下一代土地系统模型。开发一个通用的建模基础设施可以通过构建和标准化相互作用来促进交叉受精。本文提出了这样一种基础设施，即土地系统框架，其目标是中等程度的复杂性，并约束组件(和社区)之间的接口，这样做的目的是促进(子)社区模型的开发和它们的集成之间更容易的管道，既供独立使用，也用于环境管理。本文首先概述了该框架的概念设计和技术能力，然后通过案例研究说明了该框架的用法和有用的特点。这里介绍的主要创新是(1)接口约束本身；(2)在Python(统一水文学框架，Unifhy)中的实现；(3)使用该框架演示独立的用例。现有框架尚未达到我们的所有目标，特别是直接支持融入更大的环境管理系统的目标，因此，我们最后总结了当前框架的剩余局限性和必要的未来发展。
Abstract. The land surface, hydrological, and groundwater modelling communities all have expertise in simulating the hydrological processes at play in the terrestrial component of the Earth system. However, these communities, and the wider Earth system modelling community, have largely remained distinct with limited collaboration between disciplines, hindering progress in the representation of hydrological processes in the land component of Earth system models (ESMs). In order to address key societal questions regarding the future availability of water resources and the intensity of extreme events such as floods and droughts in a changing climate, these communities must come together and build on the strengths of one another to produce next-generation land system models that are able to adequately simulate the terrestrial water cycle under change. The development of a common modelling infrastructure can contribute to stimulating cross-fertilisation by structuring and standardising the interactions. This paper presents such an infrastructure, a land system framework, which targets an intermediate level of complexity and constrains interfaces between components (and communities) and, in doing so, aims to facilitate an easier pipeline between the development of (sub-)community models and their integration, both for standalone use and for use in ESMs. This paper first outlines the conceptual design and technical capabilities of the framework; thereafter, its usage and useful characteristics are demonstrated through case studies. The main innovations presented here are (1) the interfacing constraints themselves; (2) the implementation in Python (the Unified Framework for Hydrology, unifhy); and (3) the demonstration of standalone use cases using the framework. The existing framework does not yet meet all our goals, in particular, of directly supporting integration into larger ESMs, so we conclude with the remaining limitations of the current framework and necessary future developments.
