1.已经开发了一种方法来评估相对于接近自然或参考条件的河流流量状况的人为改变程度。2.邓迪水文制度改变法（DHRAM）利用美国大自然保护协会的水文变化指标方法，使用符合欧共体水框架指令要求的五类方案，对河流生态损害风险进行分类。对于河流和湖泊已经开发了不同的方法，尽管本文只考虑前者。4.DHRAM使用日平均流量时间序列数据，代表感兴趣地点未受影响和受影响的情况，涉及任何类型的人为水文影响，如蓄水、抽象化或流量增加。5.本文概述了处理不同级别可用数据的程序，利用Micro Low Flows计算机软件包生成每日平均流量的合成序列，并酌情补充流量变化数据。6.DHRAM的效用是通过一对苏格兰案例研究来证明的，说明了它在分类制度变化和支持绘图方面的能力，这将对流域管理者有价值。7.最后，讨论了当前和未来与DHRAM分数与生态破坏水平校准有关的问题。版权所有©2005 John Wiley & Sons， Ltd
1.A method has been developed for assessing the degree of human alteration of river flow regimes relative to near-natural or reference conditions. 2.The Dundee Hydrological Regime Alteration Method (DHRAM) utilizes the Indicators of Hydrologic Alteration approach of the US Nature Conservancy to classify the risk of damage to in-stream ecology using a five-class scheme compatible with the requirements of the EC Water Framework Directive. 3.Separate methods have been developed for rivers and lakes, though only the former are considered in this paper. 4.DHRAM uses daily mean flow time-series data, representing un-impacted and impacted situations for the site of interest, in relation to any type of anthropogenic hydrological impact such as impoundments, abstractions or flow augmentation. 5.Procedures for coping with different levels of data availability are outlined, utilizing the Micro Low Flows computer package to generate synthetic series of daily mean flows, supplemented by flow alteration data as appropriate. 6.The utility of DHRAM is demonstrated through a pair of Scottish case studies illustrating its ability in classifying regime alteration and supporting mapping, which will be of value to river basin managers. 7.Finally, present and future issues relating to the calibration of DHRAM scores to levels of ecological damage are discussed.
