Taking the wetland of the Liaohe River Estuary as the research object and combined with the emergy theory, aquatic product supply service, plant resource supply service, atmospheric oxygen content regulation service, atmospheric carbon dioxide content regulation service, water regulation service, biological habitat regulation service, scientific research culture service value, leisure and entertainment service value are chosen to evaluate the ecological service value of the Liaohe Estuary wetland in 2019. The results of the study show that the total emergy value of the wetland at the mouth of the Liaohe River is 59.931 billion yuan. Among them, the value of supply services is 2.057 billion yuan. The value of regulation services is 53.508 billion yuan, and the value of cultural services is 4.366 billion yuan. In the entire value of Liaohe estuary wetland, regulation service value>cultural entertainment value>supply service value. Among them, the ecological service value of Liaohe estuary wetland mainly comes from water resource regulation service value and biological habitat regulation service value. Therefore, the ecological service value Research is of great significance to the development and utilization of water resources.
