Abstract: Urban lake wetlands provide vital ecosystem services and promote sustainable urban development. However, rapid urbanization has led to the degradation and loss of wetland areas and their ecosystem services. This study aimed to examine the influencing factors of ecosystem services and summarize its ecological compensations standard of urban lake wetlands in case studies of Wuhan by using the theory and the methods of eco-economics and resource economics to assess the value of the ecosystem service functions of three urban lakes – Zhangdu, East, and Ziyang – representing natural, semi-natural, and artificial lake types respectively. The study focused on three urban lakes – Zhangdu, East, and Ziyang – representing natural, semi-natural, and artificial lake types respectively. Remote sensing data Landsat 7 ETM+ and Sentinel -2 were used to study changes in wetland area. The theory and the methods of eco-economics and resource economics were also used to assess the value of the ecosystem service functions of the wetlands from the aspects of resources functions, environment functions, and social functions. Institutional economics was used to calculate the ecological compensation of three lake wetlands. Ecosystem service values were estimated for the three lakes using market price, replacement cost, travel cost, and contingent valuation methods. Direct use values comprised aquaculture production, water conservation, and recreational services. Indirect use values included carbon sequestration, climate regulation through transpiration, water purification, flood mitigation, biodiversity maintenance, study, and education. Non-use values reflected cultural heritage and existence benefits. A household survey using contingent valuation assessed local communities’ willngness to pay (WTP) & willingness to accept (WTA) compensation for conserving urban lake wetlands. Remote sensing data revealed considerable decline in lake and wetland areas from 2002 to 2022 due to the expansion of built-up land. The tot
