摘要：

This study examined regional differences in ecosystem services for the Da Hinggan Mountains(DHM), China. A correction index was constructed based on ten-year average net primary productivity(NPP) data. A new equivalent factor table that was suitable for the assessment of wetlands in the DHM was formed by using the expert weight determination method(EWDM). An evaluation model was established for evaluating the ecosystem service value(ESV) of wetlands in the DHM. The results show that in 2020, the total ESV of wetlands reached 93 361 ×10～6 USD, with the forest swamp and marsh ecosystems contributing the most. From the perspective of value composition, regulating services and supporting services are the main service functions of wetlands in the DHM. From 2010 to2020, ESV provided by wetlands increased by 4337 × 10～6 USD/yr in the DHM. The value of forest swamp and peatland ecosystems increased by 18.6% and 12.7%, respectively, whereas the value of swamp, shrub swamp, and marsh decreased. The research results are of significance for contributing to local government performance evaluation and determining financial compensation for the provision of wetland ecosystem services.
