摘要
生态需水研究是近年来国内外广泛关注的热点.本文从生态需水的基本概念出发,论述了国内外生态需水研究的进展,总结了河道内和河道外生态需水量的计算方法.最后,提出了目前生态需水研究尤其流域尺度下的生态需水研究中亟待解决的一些问题,并且分别从空间尺度和时间尺度展望了生态需水研究的发展趋势.
Great attentions have been paid on ecological water requirement in recent years.Based on the basic concept of ecological water requirement,this paper discusses the current research status and future study on ecological water requirement,and summaries the calculation methods of ecological water requirement in river inside and outside.Finally,some problems in river basin-scale ecological water requirement study are pointed out,and from the spatial scales and temporal scales looks forward to the study of ecological water requirement trends.
