Climate change and human activities are expected to have a profound impact on the distribution of species, especially for narrowly distributed species. is endemically distributed in China, and all species are listed under Chinese protected wild species. Here, we reconstructed the phylogeny and estimated the divergence time of based on whole plastomes, conducted the niche evolution, and predicted the potential habitat area of from the LGM to the future. Our results strongly supported the monophyly of based on whole plastomes. This genus originated in the middle Miocene and diversified since the late Miocene. The aridity index was the highest significant factor for its niche evolution, and the niche evolution rate increased slowly since its divergence. The precipitation of the warmest quarter was a main environmental variable affecting the distribution of in the LGM, while the human footprint is the main variable in the near-current era and 2081-2100. Compared to the current distribution of , the highly suitable distribution area contracted in the LGM, but expanded during 2081-2100. This study provides potential areas for the in situ conservation of .
气候变化和人类活动预计将对物种分布产生深远影响，尤其是对于分布狭窄的物种。[该物种]在中国特有分布，所有物种均被列入中国保护野生动物名录。在此，我们基于全叶绿体基因组重建了[该物种]的系统发育并估计了其分化时间，进行了生态位演化分析，并预测了从末次盛冰期到未来[该物种]的潜在栖息地面积。我们的结果有力地支持了基于全叶绿体基因组的[该物种]单系性。该属起源于中新世中期，自中新世晚期以来多样化发展。干旱指数是其生态位演化的最显著因素，自分化以来生态位演化速率缓慢增加。最暖季度降水量是影响末次盛冰期[该物种]分布的主要环境变量，而人类足迹是当前及2081 - 2100年的主要变量。与[该物种]当前分布相比，末次盛冰期高度适宜分布区收缩，但在2081 - 2100年期间扩大。本研究为[该物种]的就地保护提供了潜在区域。
