摘要 通过对国内外生态环境需水量研究现状的分析 ,阐述了生态环境需水量的概念。提出生态环境需水量是由河道内生态环境需水和河道外生态环境需水、景观娱乐需水三部分组成的观点 ,从生态环境需水的时空分布、自然生态优先和可持续角度对其内涵进行了探讨 ,分析了生态环境需水量的动态性、可控制性和极限特性。对目前采取的各种生态环境需水量计算评价方法进行了总结 ,展望了该研究领域的发展趋势。 The concept of ecological and environmental water requirement was introduced and reviewed.In-channel,out-channel and entertainment required water constitute the ecological and environmental water requirement.The concept was discussed from the aspects of spatial-temporal distribution,priority of nature and sustainable utilization.The characteristic was analyzed with the dynamics,controlability and limit.The methods on calculating and evaluating ecological and environmental water requirement was summerized and the development trends in this domain were prospected.
