Water potential data and model output

Classifying the diverse ways that plants respond to hydrologic stress into generalizable ‘water-use strategies' has long been an eco-physiological research goal. While many schemes for describing water-use strategies have proven to be quite useful, they are also associated with uncertainties regarding their theoretical basis and their connection to plant carbon and water relations. In this review, we discuss the factors that shape plant water stress responses and assess the approaches used to classify a plant’s water-use strategy, paying particular attention to the popular but controversial concept of a continuum from isohydry to anisohydry.
A generalizable and predictive framework for assessing plant water-use strategies has been historically elusive, yet recent advances in plant physiology and hydraulics provide the field with a way past these obstacles. Specifically, we promote the idea that many metrics that quantify water-use strategies are highly dynamic and emergent from the...

将植物对水文胁迫（hydrologic stress）的多样响应模式归类为可推广的"水分利用策略"，长期以来都是生态生理学领域的核心研究目标之一。尽管诸多用于阐释水分利用策略的分类方案已被证实颇具实用价值，但这类方案仍存在理论基础与植物碳-水关系关联层面的不确定性。在本综述中，我们将探讨影响植物水分胁迫响应的各类因素，并评估用于划分植物水分利用策略的各类方法，尤其聚焦于这一广为人知却颇具争议的等水势调节（isohydry）-非等水势调节（anisohydry）连续谱概念。

长期以来，构建可推广且可预测的植物水分利用策略评估框架始终难以实现，但近年来植物生理学与植物水力学领域的进展为突破这一困境提供了可能。具体而言，我们主张：诸多用于量化水分利用策略的指标具有高度动态性，其特性源于……
