Spatially differentiated conservation effort for natural resources is critical to achieving a balance between protection and development in national parks. However, the extent of priority conservation areas for plants that integrate multispecies and multifaceted values is unclear. Here, we selected fine-resolution environmental variables with stronger impacts on wild plant survival to spatialize the distribution of all modeling-eligible species using species distribution models in Three-River-Source National Park, China. These were then combined with in situ conservation results for insufficient data species to identify priority conservation areas (PCAs) in terms of diversity, ecological and economic values, respectively. We analyzed the spatial characteristics of the priority conservation areas and searched for conservation gaps not covered by national nature reserves. The results showed that this study obtained more precise results on the spatial distribution of species by improving environmental variables and upgrading the spatial resolution. In Three-River-Source National Park, the species richness of wild plants showed a decreasing trend from southeast to northwest. There were significant differences in the spatial distribution of the priority conservation areas identified based on the three values, which was the basis for the spatially differentiated conservation and development of wild plant resources. In addition, the priority conservation areas obtained based on ecological value found Top17% priority conservation areas in the Hoh Xil Natural Reserve, which could not be revealed based on diversity or economic value. These results highlight the urgency of implementing multispecies and multifaceted values studies in national parks. In the future, studying conflicts between wildlife priority conservation areas and human activities, and expanding to national parks on a global scale, will be the focus that this study will continue to explore.
对自然资源进行空间差异化保护是在国家公园内实现保护与发展平衡的关键。然而，综合考虑多物种和多方面价值的植物优先保护区的范围尚不清楚。在这里，我们选择了对野生植物生存有更强影响的精细分辨率环境变量，使用物种分布模型在中国三江源国家公园对所有符合建模条件的物种的分布进行了空间化。然后，我们将这些物种分布与原位保护结果相结合，为数据不足的物种确定了多样性、生态和经济价值方面的优先保护区（PCAs）。我们分析了优先保护区的空间特征，并寻找了未被国家自然保护区覆盖的保护缺口。结果表明，通过改进环境变量和提高空间分辨率，本研究在物种的空间分布方面获得了更精确的结果。在三江源国家公园，野生植物的物种丰富度呈现出从东南向西北逐渐减少的趋势。基于三种价值确定的优先保护区的空间分布存在显著差异，这是野生植物资源空间差异化保护与发展的基础。此外，基于生态价值确定的优先保护区在可可西里自然保护区内发现了 17%的 Top17%优先保护区，而从多样性或经济价值来看则无法揭示这些保护区。这些结果强调了在国家公园内实施多物种和多方面价值研究的紧迫性。未来，研究野生动物优先保护区与人类活动之间的冲突，并扩展到全球范围内的国家公园，将是本研究继续探索的重点。
