North China University of Water Resources and Electric Power, Zhenzhou 450045) Abstract: Construction and operation of hydraulic projects have changed the hydrological regime of natural rivers and produced negative influences on river ecosystems. To improve and recover the deteriorated river environment, it is of great significance to analyze and make effective regulation of the ecological water demands by rivers. This paper describes a calculation model of these demands that was constructed through analysis of river hydrological regime and its influence on river ecosystem. This model takes river ecological restoration as its optimization goal and considers t
