Ecological economics is increasingly concerned to find appropriate ways to value wetland ecosystem. This paper examines evaluation methods and values estimation of wetland ecosystem services. The characteristics of different methods are discussed. A wetland ecosystem services value sequence is described, and value coefficients, value changes are discussed. It then describes possible future developments in the field of wetland ecosystem services valuation, which includes confirming the main services, considering assessing the influence of various other factors, developing the dynamic models for values, the establishment of an ecological compensation mechanism and investigating the flow change of the constructed wetland service values. It strengthens understanding of wetland ecosystem services values and provides theoretical support for a sustainable balance between human and wetland environments.
