Abstract: Wetlands are valuable urban resources and can provide various ecosystem services for cities. In order to face the continuous urbanization and market economy environment, relevant government-related management, decision-makers, and stakeholders can make objective and comprehensive value judgments and decide the fate of urban wetland resources. Our quantitative approach to the ecosystem services value provided by wetlands produced clear, direct, and persuasive monetization data. The assessment of the net value of ecosystem services (NES) provides one such method. Considering the transition of the Xixi Wetland into the Xixi National Wetland Park in Hangzhou as an example, we first determined the calculation model of its NES. Second, we utilized the equivalent factor, contingent valuation, travel cost, and benefit transfer methods to calculate its value of ecosystem services (VES), service cost, and NES. The results are shown below. In 2016, the VES of Xixi Wetland park was RMB 16.973 billion, NES was RMB 16.938 billion, and service cost was RMB 34.8158 million. The value of cultural services was the main contributor to NES, which accounted for 99.27% of the total. Real estate appreciation, cultural heritage, and recreational value were the main contributors to its cultural service value. Third, through the scenario comparison, we concluded that the NES of the protective development model (the wetland park mode) adopted by Xixi Wetland was RMB 3.186 billion more than that of the protection model. In other words, the protective development model is more practical and sustainable for protecting the Xixi Wetland. Finally, the limitations and shortcomings of the study are summarized.
