【摘要】 介绍了确定河流环境流量的一种新方法——变化范围法(RVA)的形成、研究现状及应用进展。在分析水文变化指标(IHA)的基础上,总结未受干扰的时间序列中的流量范围作为初始的环境流量范围,并通过监测生态影响来修正该流量范围,并论述了水文变化指标与变化范围法的关系。更多还原

【Abstract】 An introduction was made on the formation,current study and application of RVA(Range of Variability Approach),a new method used for estimating environmental flow of river.Based on the analysis of IHA,the environmental flow range of pre-impact period was taken as the initial flow range.The flow range can be revised based on the monitoring of ecologic influence.A discussion was made on the relationship between IHA and RVA.更多还原
