A Simulation of Ecological Water Replenishment for Liaohe Estuary Wetland Based on the MIKE21 Model
Liaohe estuary wetland is rich in natural resources with favourable soil and water resources,and is the habitat of many endangered animals.However,due to the problems of insufficient water resources,serious pollution and insufficient financial investment,the water resource endowment capacity of the Liaohe estuary wetland need to be improved,and the water demand of the wetland cannot be met by relying solely on the wet-land's self-recovery ability and natural water.Therefore,based on the protection objectives of the Liaohe estuary wetland,DHI MIKE21 is constructed through hydrological data and remote sensing data,long-term water replenishment simulation monitoring is carried out,and after the water replenishment effect achieves the expected goal,the water quantity interval in different water-demanding years is calculated,so that a practicable replenishment scheme for the Liaohe estuary wetland can be proposed from paths,time and sources of the replenishment,and the water resources can be allocated appropriately.The water replenishment alleviates the water shortage problem of the reed wetland,improves the ecological service function of the reed wetland,provides sufficient water area and food for a large number of migratory birds through ecological water replenishment,improves the multiple comprehensive benefits of the wetland,and protects the biodiversity.
