【摘要】:本文回顾了环境流评价方法从简单的水文公式到水文变化生态限度方法(ELOHA)的发展历程。讨论了环境流的理论要点,如自然水流与径流调节水流的区别;水文情势改变-生态响应关系以及水生态系统阈值等问题。文章还评论了环境流方法应用的若干问题,包括生态需水概念;技术文件中引用国外文献的完整性和准确性;加强数值模型研究和软件开发;推行适应性管理策略。
[Abstract]:This paper reviews the development of environmental flow assessment method from simple hydrological formula to ecological limit method of hydrological change and discusses the main points of environmental flow theory. For example, the difference between natural flow and runoff regulating flow; The relationship between hydrological situation change and ecological response and the threshold value of water ecosystem are also discussed in this paper. Some problems in the application of the environmental flow method including the concept of ecological water demand are also reviewed in this paper. Completeness and accuracy of references to foreign documents in technical documents; Strengthening numerical model research and software development; Implement adaptive management strategy.

【正文快照】: 河流生物群落对水文情势具有很强的依赖性。水资源的大规模开发和水库径流调节极大地改变了河流自然水文情势。水文情势的变化,引起河流生态系统结构与功能的变化,甚至导致淡水生态系统严重退化。为保护水生态系统,有必要在人类开发水资源的前提下,确定维持河流生态健康的基本,
