叶绿素和总磷浓度是湖泊水质的重要指标,它们之间的关系是评价湖泊营养状况的常用工具。尽管在管理环境中应用了叶绿素与总磷的关系,但对其形成的机制仍缺乏了解。我们利用一个主要关注生物地球化学和生理机制的基于过程的模型来开发一个框架,该框架协调了叶绿素-总磷关系的多个尺度驱动因素之间的相互作用,如水文磷负荷、湖泊形状和藻类生理。我们发现,湖泊形状和水文磷负荷的组合导致藻类限制状态的广泛变化,这不利于叶绿素-总磷关系的形成。此外,我们强调了藻类特性在控制限制转移方面的重要性。我们的框架将关键的景观和生态系统特征与生物限制联系在一起,并提供了对叶绿素-总磷关系的综合和基于过程的理解。
Chlorophyll and total phosphorus (TP) concentrations are key indicators of lake water quality and the relationship between them is a common tool for assessing lake trophic status. Despite the application of the chlorophyll–TP relationship in management settings, there is still an absence of a mechanistic understanding underlying its shape. We leveraged a process‐based model that focuses primarily on biogeochemical and physiological mechanisms to develop a framework that reconciles interactions between multiscale drivers of the chlorophyll–TP relationship, such as hydrologic P loads, lake shape, and algal physiology. We found that combinations of lake shape and hydrologic P load induce broad shifts in algal limitation status that underly the shape of the chlorophyll–TP relationship. Furthermore, we highlight the importance of algal traits in controlling shifts in limitation. Our framework ties key landscape and ecosystem features to biological limitation and provides a synthetic and process‐based understanding of the chlorophyll–TP relationship.
