项目摘要
Because of their critical position between terrestrial upland and freshwater systems, riparian zones are critical elements of the hydrological landscape. In addition, because of their potential role as nutrient/contaminant sink in the landscape, they are widely recommended best management practices worldwide. Nevertheless, the cumulative effect of riparian zones on water quality at the watershed scale remains poorly understood. It is crucial to develop strategies to estimate the spatial and temporal variability in contaminant removal in riparian zones and the cumulative effect of individual riparian zones on water quality at the watershed scale. There is also a need to synthesize current knowledge on nutrient fluxes through riparian systems during episodic precipitation events/snowmelt in order to be able to understand the role of riparian zones in annual nutrient fluxes. Finally, efforts need to be made to determine major gaps in knowledge impeding our ability to quantify the impact of human modifications to the environment (e.g. stream incision, artificial drainage) on riparian zone functioning, i.e. hydrological functioning (water table fluctuation/depth, subsurface flow path, groundwater fluxes, seasonality) and biogeochemical functioning (P-adsorption, redox conditions, vegetation uptake, denitrification...). The main objectives of this workshop are therefore 1) to synthesize current knowledge on approaches/techniques that could be used to determine riparian zone hydrological and biogeochemical functionning and the role of riparian zones as nutrient/contaminant sinks at the watershed scale, and 2) to identify gaps in knowledge and major research challenges that will need to be overcome to achieve this goal.We propose to bring together 30 scientists/students working on various aspects of riparian zone hydrology and biogeochemistry and/or on the linkages between the terrestrial and aquatic boundary to address these objectives. The workshop will specifically focus around three integrative themes:1) Can we develop a decision matrix taking into account landscape hydrogeomorphic, vegetation, climatic and land use characteristics to generalize riparian zone function at the watershed scale?2) Can a decision tree using landscape hydrogeomorphic characteristics, vegetation, climatic and land use data be developed to classify riparian zone function during dynamic hydrologic conditions?3) How do human induced changes in riparian zone form impact riparian zone function, and how can we integrate these changes at the watershed scale?The workshop will be open to all individuals that are involved in riparian zone research and interested in developing tools/strategies to identify the role of riparian zones as nutrient/contaminant sinks at the landscape scale. This will include students and scientists from academic institutions, government agencies and private partners involved in riparian zone management.The intellectual merit of this workshop proposal includes bringing together riparian scientists to identify future research needs in riparian zone research and especially strategies to better understand the role of riparian zones at the watershed scale, write review papers and host special sessions at conferences.The broader impacts of our proposed activity include developing interactions between promising graduate students, post-doctoral fellows and university, government and private sector scientists, and contribute to the development of better strategies to manage riparian zones at the watershed scale in order to mitigate the impact of non-point source pollution on water quality. We expect that the findings from this workshop will have far reaching implications for society by contributing knowledge to riparian zone management to meet our society's objectives in term of environmental quality in the 21st century.
由于河岸带位于陆地高地和淡水系统之间的关键位置,它是水文景观的关键要素。此外,由于它们在景观中作为养分/污染物汇的潜在作用,它们在世界范围内被广泛推荐为最佳管理做法。然而,在流域尺度上,河岸带对水质的累积效应仍然知之甚少。在流域尺度上,制定策略来评估河岸带污染物去除的时空变异性和单个河岸带对水质的累积效应是至关重要的。还需要综合目前关于在偶发性降水事件/融雪期间通过河岸系统的养分通量的知识,以便能够了解河岸带在年养分通量中的作用。最后,需要努力确定阻碍我们量化人类对环境的改变(例如河流切割、人工排水)对河岸带功能的影响的主要知识差距,即水文功能(地下水位波动/深度、地下水流路径、地下水通量、季节性)和生物地球化学功能(p吸附、氧化还原条件、植被吸收、反硝化等)。因此,本次研讨会的主要目标是:1)综合目前关于方法/技术的知识,这些方法/技术可用于确定河岸带水文和生物地球化学功能,以及河岸带在流域尺度上作为养分/污染物汇的作用;2)确定知识上的差距和为实现这一目标需要克服的主要研究挑战。我们建议召集30名科学家/学生,研究河岸带水文学和生物地球化学的各个方面和/或陆地和水生边界之间的联系,以实现这些目标。研讨会将围绕以下三个综合主题展开:1)我们能否建立一个综合考虑景观水文地貌、植被、气候和土地利用特征的决策矩阵来概括流域尺度上的河岸带功能?2)在动态水文条件下,是否可以利用景观水文地貌特征、植被、气候和土地利用数据建立决策树对河岸带功能进行分类?3)人类活动导致的河岸带形态变化如何影响河岸带功能,如何在流域尺度上整合这些变化?研讨会将向所有参与河岸带研究并有兴趣开发工具/策略以确定河岸带在景观尺度上作为营养/污染物汇的作用的个人开放。这将包括来自学术机构、政府机构和参与河岸带管理的私人合作伙伴的学生和科学家。这个研讨会提案的智力价值包括将河岸科学家聚集在一起,确定未来对河岸带研究的需求,特别是更好地理解流域尺度上河岸带的作用的策略,撰写评论论文和在会议上主持特别会议。我们提议的活动的更广泛的影响包括发展有前途的研究生、博士后研究员和大学、政府和私营部门科学家之间的互动,并有助于制定更好的战略来管理流域尺度的河岸带,以减轻非点源污染对水质的影响。我们期望研讨会的研究成果能对社会产生深远的影响,为河岸地带的管理提供知识,以达到二十一世纪社会在环境质素方面的目标。
