Abstract
Wetlands are considered as one of the most important ecosystems on the Earth. Rapidly urbanizing, being an intense way of human activities, has brought significant impact on the ecological functions of urban wetlands. This study focused on the urban wetland ecosystem in the Nanjing Jiangbei New Area, China, and presented a dynamic integrated approach to assess the monetized value of its services. A classification decision tree model was adopted to interpret the Landsat TM/ETM/OLI images to obtain the LUCC data of urban wetlands in different years. Then an integrated approach was employed to correct the equivalent values and their prices of various ecosystem services, dynamically evaluating the value of wetland ecosystem services. The results showed that the overall value of the wetland ecosystem services of the Jiangbei New Area was 893.99 million USD, 1365.63 million USD and 1016.46 million USD in 2002, 2009 and 2015, respectively. Among the service categories, the regulating service reaches the most and the provisioning service contributes the least to the total value. According to the analysis of annual valuation results, it was inevitable that the ecological conditions of wetlands in the rapidly urbanizing area would deteriorate and the capability to provide ecosystem services would degenerate. This research suggests that rapid urban development should adopt an ecosystem service oriented strategy to align sustainable utilization with conservation and to recognize the interaction between the wetland ecosystem services and the forces of urbanization.
