Preserving wilderness areas is one of the key goals in the Post-2020 Global Biodiversity Framework(GBF). However, far too little attention has been paid to identifying wilderness conservation priorities on the national scale. In this study, we developed a methodological framework to evaluate the ecosystem service values, potential loss and conservation priorities of wilderness areas in China, providing guidance for wilderness conservation. First, we assessed the conservation value of wilderness areas and found that wilderness areas provided more ecosystem services than non-wilderness areas per unit area in most ecoregions. Then we identified threatened wilderness areas under multiple scenarios due to land use and land cover change. We found that 5.82 % of the existing wilderness areas were projected to be lost by 2100. Finally, wilderness conservation priorities were identified considering both conservation values and potential loss, and 11.24 % of existing wilderness areas were highlighted as conservation priorities. This methodological framework could be applied to other countries to support post-2020 global biodiversity conservation.
保护荒野地区是 2020 年后全球生物多样性框架（GBF）的主要目标之一。然而，在国家范围内确定荒野保护优先事项方面，关注的力度还远远不够。在本研究中，我们开发了一种方法框架，以评估中国荒野地区的生态系统服务价值、潜在损失和保护优先事项，为荒野保护提供指导。首先，我们评估了荒野地区的保护价值，发现在大多数生态区，单位面积的荒野地区提供的生态系统服务比非荒野地区多。然后，我们根据多种情景下的土地利用和土地覆盖变化，确定了受到威胁的荒野地区。我们发现，到 2100 年，预计现有的 5.82%的荒野地区将会消失。最后，我们考虑到保护价值和潜在损失，确定了荒野保护的优先事项，现有荒野地区的 11.24%被确定为保护优先事项。这种方法框架可以应用于其他国家，以支持 2020 年后的全球生物多样性保护。
