ABSTRACT

Since the 1960s, theoretical and empirical advances in limnology have offered lake managers different approaches to address lake eutrophication problems. The Vollenweider input–output model and the Scheffer model of alternative stable states are 2 well-known applications of the stressor–response (S-R) models. The 2 applications each utilise particular S-R relationship shapes. However, lake eutrophication response variables and shapes of S-R relationships may vary greatly from lake-to-lake, highlighting a key question for lake managers: What is the appropriate shape of the S-R relationship for a given lake eutrophication problem? This study develops an S-R lake framework that embraces multiple functional forms of S-R relationships. First, 3 New Zealand lake eutrophication case studies are presented in which different S-R relationships were used to inform management actions. Then, the different usages of the S-R framework illustrated by the case studies are discussed, including the different types of data used and how information about feedbacks and other mediating factors helped identify the S-R relationships. Finally, a lake typology is presented, linking specific lake types to specific S-R relationship shapes, to assist with managing lake eutrophication under conditions of changing stressors and stressor levels.

应激反应关系在湖泊富营养化管理中的应用

抽象的

自1960年代以来,湖泊学的理论和经验发展为湖泊管理者提供了解决湖泊富营养化问题的不同方法。Vollenweider输入-输出模型和替代稳态的Scheffer模型是应力-响应(SR)模型的2个众所周知的应用程序。这两个应用程序各自利用特定的SR关系形状。但是,湖泊富营养化响应变量和SR关系的形状在不同湖泊之间可能存在很大差异,这突出了湖泊管理者的一个关键问题:对于给定的湖泊富营养化问题,SR关系的适当形状是什么?这项研究开发了一个SR湖框架,该框架包含SR关系的多种功能形式。第一的,提出了3个新西兰湖泊富营养化案例研究,其中使用了不同的SR关系来告知管理措施。然后,讨论了案例研究说明的SR框架的不同用法,包括使用的不同类型的数据以及有关反馈和其他中介因素的信息如何帮助确定SR关系。最后,提出了湖泊类型学,将特定的湖泊类型与特定的SR关系形状联系起来,以帮助在压力源和压力源水平变化的情况下管理湖泊富营养化。
