Research and prospects of ecohydrology under the"dual carbon"goals
Under the"dual carbon"goals,global climate change and carbon reduction have become central issues of our era.Achieving carbon neutrality requires addressing the interconnections of terrestrial,marine,and atmospheric water and carbon cycles,particularly at the watershed scale.As an interdisciplinary field combining hydrology and ecology,ecohydrology provides critical water science support for achieving carbon peaking and carbon neutrality.This study systematically summarizes key advancements in ecohydrology across its subfields,including vegetation ecohydrology,river and lake ecohydrology,and watershed ecohydrology.Focusing on core scientific challenges,it is proposed that future ecohydrology research within the framework of"dual carbon"goals should emphasize innovative carbon sink technologies for natural ecosystems.Key areas include land-climate interactions,the"dual carbon"challenges posed by urbanization and agricultural intensification,carbon issues related to river and reservoir construction and operations,and integrating ecohydrological approaches with circular economy and nature-based solutions.To further the development of ecohydrology as a cross-disciplinary field,the study recommends prioritizing research on river health and circular economy-oriented ecohydrology and advancing urban and regional development models that integrate natural ecosystems with circular economy principles.Finally,the paper highlights future research directions and priorities for ecohydrology,aligning with its strategic significance and practical needs.
