摘　　要：采用最大熵模型(maximum entropy model,MaxEnt)对松茸(Tricholoma matsutake)在云南省的分布规律及其对气候变化的响应进行了研究。结果表明,云南松茸的适生区主要集中在哀牢山以东以北的高原山地区域,随着海拔升高适生指数逐渐提升,在海拔2 000 m以上的地区松茸的适生指数在0.6以上。伴随着全球气候变化,云南省范围内松茸适生区呈现逐步缩小的趋势,云南西部和滇中高原受影响的程度将大大高于滇西北高海拔地区,3 000 m以下地区的松茸适生指数将下降到0.5以下,而海拔4 000 m以上地区的松茸适生指数则有所升高。总体而言,松茸对气候变化较为敏感,未来的资源保护和人工抚育工作的侧重点也需要向高海拔地区倾斜。The distribution regularity of Tricholoma matsutake in Yunnan province and its response to climate change were studied using the maximum entropy model （MaxEnt）. Our data revealed that the suitable area of T. matsutake in Yunnan was mainly concentrated in the plateau area of the north of the Ailao Mountain Mountains. The fitness index of T. matsutake was higher than 0.6 in the areas above 2 000 m. Along with the global climate change, the suitable area of T. matsutake in Yunnan province is gradually shrinking, and the extent of the influence on the western and central Yunnan plateau will be much higher than that in the high-elevation region of northwest Yunnan. The fitness index of T. matsutake in the area below 3 000 m will decrease to below 0.5, while the fitness index for the area above 4 000 m will be increased. In general, T. matsutake is very sensitive to global warming, and the resource protection and artificial cultivation of this valuable mushroom also needs to be tilted to high altitude areas.
