Abstract
The main purpose of studying wetland ecological water demand is to grasp the best matching water demand of the ecosystem health.Two methods of calculating the wetland ecological water demand are proposed respectively from the management targets of maintaining the ecological function of habitats and the reasonable scale of eco-hydrological structure.The ecological water demand of estuary wetland of Yellow River is calculated and the ecological flow which should be released by Lijin section is backstepped.
