[Objective] To evaluate the urban ecosystem health of Jiaozuo City in order to further improve the level of the city ecosystem health, optimize the economic structure, ensure the continuous reduction of pollutants emissions. [Methods] Considering indices's completeness, representativeness, comparability, maneuverability, as well as the new situation of emissions reduction and ecological civilization, the assessment indices system of urban ecosystem health of Jiaozuo City was put forward, which contains five aspects: vigor, organizational structure, resilience, ecosystem service and population health of urban ecosystem. The health state of Jiaozuo city during 2006-2012 was evaluated with the entropy-weight method. [Results] The health state of urban ecosystem of Jiaozuo City kept improving during 2006-2012, and the indices of vigor and population health of Jiaozuo City increased steadly. Although the indices of resilience and ecosystem service of urban ecosystem had fluctuated, that increased significantly during the study period. The variation of economic structure caused in a small fluctuation of organizational structure. The changes of pollutant emissions and utilization rate of solid waste were the main reasons to cause the variety of resilience and ecosystem service of Jiaozuo City. [Conclusion] To improve the level of urban ecosystem health of Jiaozuo City, it should optimize economic structure and ensure the continous reduction of pollutants emissions.
