The next step for China?s national park management: Integrating ecosystem services into space boundary delimitation

The contradiction between ecological conservation and economic development posed significant challenges to the management of National Parks. From the perspective of Ecological Economics, the cause of the contradiction is the difficulty of creating monetary profits from biodiversity conservation, which is the primary target of National Parks. Integrating Ecosystem Services (ESs) into space boundary delimitation is the next step in Na-tional Park management since ESs are closely related to human well-being and can provide monetary benefits. Extending the boundary of the National Park to high-ES areas and promoting ES trading can help generate funds for ecological restoration. Using the Sanjiangyuan National Park (SNP) as an example, this study proposed integrating ESs into National Park delimitation for sustainable National Park management. It was found that the current SNP boundary provides insufficient coverage of high-ES areas, while most of the multiple ES supply areas were dispersed to SNP's southeast edge. The Core conservation area showed the most prominent contradiction between ecological conservation and economic development, resulting in many low-level ES sites in the Traditional use area failing to be included in the Restoration area for protection. Future approaches would be well-advised to re-adjust SNP boundary by expanding the ES hotspot areas on the southeastern edge of SNP, as well as expanding funding sources via ecological product trade and other tools to supplement the input for ecological restoration. Overall, this study can act as a reference for optimizing National Parks within and beyond China, and promote the understanding of the Ecological Economy and sustainable development.

Automated summary

Integrating ecosystem services into National Park management can address the contradiction between ecological conservation and economic development. Using the Sanjiangyuan National Park as a case study, this research proposes integrating ecosystem services into National Park delimitation for sustainable management. It is found that the current boundary of the National Park does not sufficiently cover high ecosystem service areas, and multiple ecosystem service supply areas are dispersed to the southeast edge of the park. Therefore, it is recommended to adjust the park's boundary by expanding the ecosystem service hotspot areas on the southeastern edge and diversifying funding sources for ecological restoration.
