摘　　要：生态需水是国内外生态水文学研究的热点问题。回顾了我国西北干旱半干旱地区生态需水研究的现状,并对今后生态需水研究进行了展望。研究认为,目前我国内陆干旱区生态需水研究取得了很大的进展,但是还存在一些问题,如生态需水还没有明确统一的定义;研究方法也是因人而异;研究中的尺度转换问题;建立生态需水与生物多样性、生境多样性和生态系统健康状况相关联的指标体系。Ecological water requirement is the hot issue of eco-hydrology study both at home and abroad.Reviewing the study status of ecological water requirements of arid and semi-arid areas in northwest China,the paper puts forward the prospect of future studies on ecological water requirements.In the paper,it is demonstrated that the current study on ecological water requirements in arid area of inland has achieved great progress,but still exposing some problems,for example,there is still not yet a unified definition about ecological water requirement;the research methods also vary with different researchers,the problem of scale transfer in research and the establishment of an index system which associates ecological water requirements with the biological diversity,habitat diversity and ecosystem health.
