As the largest freshwater lake in north China, Baiyangdian Wetland plays an important role in ecological balance of the north China plain. Besides the high ecological value, Baiyangdian Wetland retains a health development of social economy. According to this special shallow freshwater wetland, based on the concept of coordinated development of resources, environment and social economy, the relativity of water resources subsystem, ecological subsystem and socioeconomic subsystem has been explained in detail, and a hierarchy that has three layers has been built up, and what’s more, the health index (HI) has been calculated using analytic hierarchy process (AHP). The results showed that the water resources-ecological-socioeconomic system of Baiyangdian Wetland was at the status of sub-health even at the high frequency water level (7.9 m). When the water level is higher or lower than 7.9 m, the health condition will be worse. Every subsystem is a chain of the coupling system, whichever of the subsystems changes will affect other chains. Thus, it is necessary to implement management measures according to the coupling mechanism of different subsystems; it can provide theoretic and practical guidance to the coordinated development of ecological balance and social economy of Baiyangdian Wetland.
