Species conservation actions are guided by available information on the biogeography of the protected species. In this study, we integrated the occurrence data of Siberian musk deer ( L.) collected from 2019 to 2021 with species distribution models to estimate the species' potential distribution in Northeast China. We then identified conservation priority areas using a core-area zonation algorithm. In addition, we analyzed core patch fragmentation using FRAGSTATS. Lastly, we identified potential connectivity corridors and constructed a potential protection network based on the least-cost path and the circuit theory. The results showed concentrations of in the northern Greater Khingan Mountains, the southeastern Lesser Khingan Mountains, and the eastern Changbai Mountains, with a potential distribution area of 127,442.14 km. Conservation priority areas included 41 core patches with an area of 106,306.43 km. Patch fragmentation mainly occurred in the Changbai Mountains and the Lesser Khingan Mountains. We constructed an ecological network composed of 41 core patches and 69 linkages for in Northeast China. The results suggest that the Greater Khingan Mountains represent the most suitable area to maintain the stability of populations in Northeast China. Considering the high habitat quality requirements of and its endangered status, we propose that the Chinese government accelerates the construction of the Greater Khingan Mountains National Park and the Lesser Khingan Mountains National Park and enlarges the Northeast China Tiger and Leopard National Park to address the fragmentation of protected areas and the habitat of .
物种保护行动以受保护物种生物地理学的现有信息为指导。在本研究中，我们将2019年至2021年收集的原麝（Moschus moschiferus L.）出现数据与物种分布模型相结合，以估计该物种在中国东北的潜在分布。然后，我们使用核心区域分区算法确定保护优先区域。此外，我们使用FRAGSTATS分析核心斑块破碎化情况。最后，我们确定潜在连通走廊，并基于成本最低路径和电路理论构建潜在保护网络。结果表明，原麝集中分布在大兴安岭北部、小兴安岭东南部和长白山地区，潜在分布面积为127442.14平方千米。保护优先区域包括41个核心斑块，面积为106306.43平方千米。斑块破碎化主要发生在长白山和小兴安岭。我们构建了一个由41个核心斑块和69条连接廊道组成的中国东北原麝生态网络。结果表明，大兴安岭是维持中国东北原麝种群稳定的最适宜区域。考虑到原麝对栖息地质量要求较高及其濒危状况，我们建议中国政府加快大兴安岭国家公园和小兴安岭国家公园的建设，并扩大东北虎豹国家公园，以解决保护区破碎化和原麝栖息地问题。
