摘要
人类活动对水资源的集约高效利用使流域内水文循环产生了二元分化,天然、人工水循环的此消彼长,改变了水资源在人工绿洲、天然绿洲及过渡带之间的时空分布和转化条件.以玛纳斯河流域为例,通过考虑水的天然循环与人工水循环(二元水循环),后者包括水资源开发利用率、耗水率、污水排放浓度影响,探讨了二元水循环下河流生态需水"质"与"量"的综合评价,以区别以往仅从天然水循环(一元)出发评价河流生态需水的缺陷.建立了二元水循环下的河流生态需水的水量与水质计算方法,实现了对玛纳斯河流域河流生态需水水量与水质的综合评价.
Manasi River basin with intensive and efficient exploitation of water resources by human being has transformed the course of water circle and unity of ecologic service from the circle course and circle peculiarity in arid region. Taking the Manasi River basin for example, based on analyzing the relationship among environmental flows of river requirements, the efficiency of water resource utilization and the consumption coefficient, and discharge concentration of waste water, the water quantity and water quality calculation method of environmental flows of river requirements in dualistic water cycle is developed; and the criteria for environmental flows of Manasi River requirements are established.
