生态环境需水的理论和方法研究进展

Advances in Researches on the Theories and Methods of Eco-Environmental Water Demand

生态环境需水研究是目前国际上学科前沿研究之一,涉及生态学、水文学、环境科学等多学科。文章论述了国内外生态环境需水研究的进展,分析了生态环境需水的内涵、概念、分类和特征,总结了河流、植被、湖泊、湿地和城市生态系统生态环境需水量计算的理论基础和方法。最后,从区域水资源优化配置和可持续发展的角度,对今后生态环境需水研究的方向与技术、区域性范围和水资源优化配置等问题进行了讨论。

Eco-environmental water demand is one of global foci research subjects in environmental related field, which has an inter-relationship with ecology, hydrology, environmental science etc. This paper discusses the current research status and future study on eco-environmental water demand, analyses the intention, concept, sort and character of eco-environmental water demand, and studies the calculation theory and methods. On the basis of above analyses, some question about current study on eco-environmental water demand are put forward for reasonable water allocation and sustainable development.
