Ecohydrology

加拿大生态水文学研究主席将调查与水资源有关的生态系统服务。特别是，研究将侧重于（i）农业系统的生态水文学，注意到人类用水的70%以上用于农业;（ii）生态水文系统中的碳通量，解决水循环和碳循环如何相互作用的问题;和（iii）提高管理的生态水文系统的复原力。研究方法将包括实地实验、遥感和建模方法。关键的合作将发展，以确保与研究用户和利益相关者的参与，同时提供新的培训机会，以学生和博士后fellows.The拟议的CRC计划旨在提高我们的水资源，生态功能和土地利用实践之间的相互作用和反馈的基本理解。生态水文学研究计划的中心目标是评估土地利用实践如何影响耦合的水文和生态过程，以及对这些生态水文过程的影响如何进一步影响生态系统服务，包括碳固存。具体目标是描述农业生态系统中的生态水文控制，反馈和压力，利用遥感和基于模型的方法，扩大对景观和全球尺度的生态水文控制的研究，描述生态水文对碳排放通量的控制，该计划将继续研究水文学和生态学之间的反馈，采用整合自然和管理的土地-水系统的基础和应用研究的方法。该研究计划的应用层面包括调查在当前和未来气候条件下提高土地利用实践与淡水安全的可持续性的战略。

The Canada Research Chair in Ecohydrology will investigate ecosystem services related to water resources. In particular, research will focus on (i) ecohydrology of agricultural systems, noting that more than 70% of human water use is for agriculture; (ii) carbon fluxes in ecohydrological systems, addressing questions of how the water cycle and the carbon cycle interact; and (iii) improving the resilience of managed ecohydrological systems. Research approaches will include field-based experiments, remote sensing and modelling approaches. Key collaborations will be developed to ensure engagement with research users and stakeholders while providing novel training opportunities to students and postdoctoral fellows.The proposed CRC program is designed to improve our fundamental understanding of interactions and feedbacks among water resources, ecological functions and land use practices. The central objective of the program of research in ecohydrology is to evaluate how land use practices influence coupled hydrological and ecological processes, and how impacts on these ecohydrological processes further affect ecosystem services including carbon sequestration.Specific objectives are to characterize ecohydrological controls, feedbacks and stressors in agroecosystems, scale-up research on ecohydrological controls to the landscape and global scales using remote sensing and model-based approaches, characterize ecohydrological controls on carbon drainage fluxes, and characterize ecohydrological resilience in relation to novel soil and water management strategies, including the strategic use of biochar.The program will continue to examine feedbacks between hydrology and ecology using approaches that integrate basic and applied research in natural and managed land-water systems. Applied dimensions of the research program include the investigation of strategies to improve the sustainability of land use practices vis-à-vis freshwater security under current and future climatic conditions.
