图2. 不同历史时期观光木的地理分布模式。A, 末次盛冰期到全新世中期的分布变化。B, 全新世中期到现代的分布变化。C, 现代到未来2070s的分布变化。D, 四个时期物种丰富度和加权特有分布的叠加分布图。E, 几何中心位移以及矢量重叠密度情况, 白色圆点表示末次盛冰期几何分布中心, 黑色圆点表示全新世中期几何分布中心, 红色圆点表示现代几何分布中心, 蓝色圆点表示未来几何分布中心, 黑色箭头表示几何分布中心变化。

Fig. 2. Major distribution changes of Tsoongiodendron odorum between different periods simulated by MaxEnt. A, Distribution changes from the Last Glacial Maximum to Mid-Holocene. B, Distribution changes from the Mid-Holocene to Current. C, Distribution changes from the current to the future. D, Summed distributions and micro-endemism during the four periods (Last Glacial Maximum, Mid-Holocene, current and future). E, Core range shifts and the line densities, white dots represent the Last Glacial Maximum centroid, black dots represent Mid-Holocene centroid, red dots represent current centroid, blue dots represent future centroid, black arrow represent centroid change.
