Wetlands support ecosystems with great biodiversity all over the world, which are highly productive and valuable, also provide a large array of benefits to human well-being society. The ecosystem services refer to the actual and potential benefits provided to human beings by wetlands, which include provisioning services, such as timber, food and water; regulating services, such as regional climate regulation and flood regulation; supporting services, such as soil formation, biodiversity and nutrient cycling; and cultural services, such as recreational and aesthetic. On one hand, wetland ecosystems are confronted with serious degradation due to human activities such as industry pollution and overexploitation; On the other hand, the demand for wetland ecosystem services is rapidly increasing as populations and living quality increase in recent years, but the public characteristics of the goods and services they provide often result in wetland being undervalued in policy and decision making. The importance of wetland ecosystem to human well-beings has many aspects (ecological, social, economic and so on), and evaluating the ecosystem services in monetary units is an effective tool to raise protection awareness of wetland to citizen, which could promote the transform form traditional national economy calculation system to the integrated calculation system of economy-environment. Through selecting open published literatures related to wetland ecosystem service valuation all over China, this study collected 68 papers, from which 71 primary cases about wetland valuation were obtained, including marsh, lake and river wetland. Data in the primary cases should include individual wetland location, area, type, ecosystem services and the value, and then the dataset of wetland ecosystem service value in SPSS software was constructed. The wetland service value of each type in the dataset was standardized to the unit 10⁴ yuan km^-2 a^-1 in 2008 by GDP indices. Valuation results of various wetland ecosystem service types and location were compared and analyzed. The conclusions of this study are: (1) the wetland ecosystem valuation result of each service type is as follows: climate regulation > water regulation > water retention > waste treatment > soil retention > production > carbon regulation > oxygen regulation > habitat > tourism > science, which also means the contribution degree of each service type in wetlands to the environment. (2) There has certain positive correlation between wetland area and ecosystem service value, which was verified after data collection and processing from case studies. However the quantitative relationship between wetland value result and multiple factors are still in progress, which need further research. (3) Through wetland ecosystem value analysis and comparison at regional scale, the wetlands in northeast plain and mountains region, east region and Qinghai-Tibet plateau have obvious and positive effect at regulation and supply functions, where also have concentrated distribution of wetland. Considering the value characteristic of wetland ecosystem service at different geographical regions could help to realize the coordinated development between regional economy and environmental ecology, thus providing scientific and reliable reference scheme for wetland conservation and development.
