Spatial scale of influence of riparian and catchment land use on stream ecosystem health

景观尺度上的人类活动是对河流生态系统生态完整性的最大威胁之一。 澳大利亚各地的政府和社区团体都在河岸保护和恢复方面做出了重大努力，试图改善退化水道的健康状况，但在实现每一美元或每一单位投资的环境收益最大化的目标方面受到了阻碍。 关于了解土地利用影响的空间尺度和对河流生态系统的综合影响的拟议研究将提供一个强有力的框架，以评估各种选择并优化管理行动的效益。

Human activities at the landscape scale comprise one of the greatest threats to the ecological integrity of river ecosystems. Government and community groups across Australia are making significant efforts in riparian protection and rehabilitation in an attempt to improve the health of degraded waterways but are hampered in their goal to maximise the environmental gains for every dollar or unit effort invested. The proposed research on understanding the spatial scale of influence of land use and the aggregative effects on stream ecosystems will provide a robust framework to assess various options and optimise benefits from management actions.
