摘　　要：生态需水是目前环境科学和水文水资源科学研究热点之一,但是其理论和研究方法还不尽完善。总结分析了国内外生态需水的不同概念及其计算方法,认为建立生态需水概念首先要明确生态目标,计算时需考虑水质,今后区域生态需水量计算方法研究是生态需水方法研究的主要方向。Ecological water demand was one of the foci research focus,but its theory and calculation methods were not perfect.The concept and methods were discussed.This paper pointed out that ecological goal should be nailed down and water quality should be taken into account while the ecological concept was built up.The calculation method of regional ecological demand would be an important research direction.
