Incorporating biodiversity, ecosystem services (ESs) and climate change adaptation into the conservation targets of protected areas (PAs) is being acknowledged. Targeting conservation actions requires a thorough understanding of the relationship between PAs and these important regions. However, few studies have identified conservation gaps while simultaneously considering these three aspects. Here, we assessed the representativeness of the PAs network for biodiversity, ESs and climate refugia (as a proxy for climate change adaptation ability) on the Tibetan Plateau (TP). Our analysis showed that these priority conservation regions were primarily located in the south and southeast of the TP, while they were impacted by intense human pressure. Most ESs and all types of species richness showed a significant positive correlation. Additionally, a positive correlation between multiple climate refugia and different types of species richness was detected. Representativeness analysis revealed notable conservation gaps for these three aspects in existing PAs, highlighting the urgency of adjusting their distribution and improving their representativeness. By integrating these conservation targets, priority regions for future conservation were further delineated. Taken together, our findings contribute to improving the efficiency of PAs and optimizing conservation planning.
将生物多样性、生态系统服务（ESs）和气候变化适应纳入保护区（PAs）的保护目标已得到认可。目标明确的保护行动需要深入了解 PAs 与这些重要区域之间的关系。然而，很少有研究同时考虑这三个方面来确定保护空缺。在这里，我们评估了青藏高原（TP）保护区网络在生物多样性、生态系统服务和气候避难所（作为气候变化适应能力的代理）方面的代表性。我们的分析表明，这些优先保护区域主要位于 TP 的南部和东南部，同时受到强烈的人类压力的影响。大多数生态系统服务和所有类型的物种丰富度均呈显著正相关。此外，还检测到多种气候避难所与不同类型的物种丰富度之间存在正相关关系。代表性分析表明，现有保护区在这三个方面存在明显的保护空缺，这凸显了调整其分布和提高代表性的紧迫性。通过整合这些保护目标，进一步划定了未来保护的重点区域。总之，我们的研究结果有助于提高保护区的效率和优化保护规划。
