Facing rapid ecological degradation in the Qinghai Tibet Plateau (QTP), the determination of priority areas for conservation (CPAs) based on ecosystem services (ESs) is a key step for nature conservation and sustainable development. However, the trade-off between services makes the plan of maintaining protected areas (PAs) a challenge. In this study, by quantifying a variety of essential ESs in the QTP from 2000 to 2015, we used the multi-criteria ordered weighted average method to balance the trade-offs and determine the key CPAs for ES conservation. We found that the multi-criteria based selection of CPAs leads to higher (1.35) and more balanced ES protection efficiency (PE) than the single strategy. The CPAs obtained based on the logical framework of this paper are mainly located in the southeastern QTP and cover an area of 12.78 % of the QTP (330,124.76 km²). The comprehensive PE of ES was 1.68, and the PE of carbon storage, water yield, soil conservation, and cultural service were 2.20, 2.17, 4.54, and 1.59, respectively. Additionally, compared with the existing PA settings, our results can increase the proportion of biodiversity of amphibians and birds by more than 12 %. The framework of CPAs selection in this paper can provide a reference for the government’s growing nature conservation affairs, which will contribute to sustainable development.

面对青藏高原（QTP）快速生态退化，基于生态系统服务（ES）确定优先保护区域（CPA）是自然保护和可持续发展的关键步骤。然而，服务之间的权衡使得维护保护区 (PA) 的计划成为一项挑战。在本研究中，通过量化 2000 年至 2015 年 QTP 中各种基本 ESs，我们使用多标准有序加权平均方法来平衡权衡并确定 ES 保护的关键 CPA。我们发现，与单一策略相比，基于多标准的 CPA 选择导致更高 (1.35) 和更平衡的 ES 保护效率 (PE)。基于本文逻辑框架得到的 CPA 主要位于青藏高原东南部，覆盖面积 12 个。²）。ES综合PE为1.68，碳储量、产水量、水土保持和文化服务PE分别为2.20、2.17、4.54和1.59。此外，与现有的 PA 设置相比，我们的结果可以将两栖动物和鸟类的生物多样性比例提高 12% 以上。本文的注册会计师遴选框架可为政府日益增长的自然保护事务提供参考，为可持续发展做出贡献。
