Multiple Criteria Assessment of Ecosystem Services Sustained by Qinhuai River in Nanjing
This paper demonstrates how to integrate social factors into the ecosystem service appraisal with a social welfare weight using Qinhuai River as a case study. The AHP method is used to determine the social weight. With analysis of the Qinhuai Rivers functions, stakeholders and ecosystem services, a three-level hierarchical structure model is established. Ecosystem services provided by the Qinhuai River would include water supply, water regulation, recreation, gas regulation and water purification. After each ecosystem service was calculated, the total value of the Qinhuai River is determined by introducing the social welfare weight. After including the social welfare weight, the value of the Qinhuai River ecosystem services increases froml. 127× 1099US$/yr to 3.226× 109USS/yr. These results will allow decision makers to compare the benefits generated by different water uses, including environmental services, and to manage scarce water resources under a long-term sustainable approach.
