【 摘 要 】

To analyze the service function value of urban wetland ecosystems, a functional value assessment system was done for Xi'an Chan-Ba wetland. Using market value method, carbon tax law and afforestation cost method, alternative cost method, travelling cost method and so on, those values were converted into economic value and a summary of the same was made for comparison. The total service function value of Chan-Ba wetland ecosystem is 3.87 108 . Of this, the value of wetland leisure tourism is the highest (accounting for 55.76%), followed by the value of carbon fixation and oxygen release from the wetland (accounting for 25.56%), other functional values accounting for smaller proportions. The value of ecosystem functions in Xi'an Chan-Ba wetland plays an important role in development of the urban economy. In that context, it should be reasonable to develop and protect the urban wetland ecosystem, and promote the virtuous circle of the urban wetland ecosystem.
