%X We predicted the potential distribution of spruce under the future climate change with <em>Picea likiangensis</em> and <em>P.purpurea</em> in Qinghai-Tibet Plateau. MaxEnt model was used to predict the potential distribution of the two species under two future climatic scenarios-2050s and 2070s. Further, we used ArcGIS software to determine the distribution area and spatial pattern of both species. The results indicatedthat:(1)Southwestern Sichuan and eastern Tibet regions were the potential distribution areas of <em>P.likiangensis</em>, while northwestern Sichuan, southern Gansu, southeastern Qinghai and eastern Tibet were the areas that would favor the potential distribution for <em>P.purpurea</em>. (2)In two future climatic periods, distribution areas of <em>P.likiangensis</em> generally increase, whereas, in case of <em>P.purpurea</em>, the distribution areas first increase and then decrease. However, the area of the total suitable distribution increase toso me extent, compared with the area of current distribution. (3)The potential distribution of <em>P.likiangensis</em> was likely to disperse towards north while <em>P.purpurea</em> to the west. (4)Moreover, the precipitation of warmest quarter and the mean temperature of warmest quarter were the primary climatic factors affecting the distribution of <em>P.likiangensis</em> and <em>P.purpurea</em>. This study can provide a theoretical basis and reference value for the sustainable management and conservation of <em>P.likiangensis</em> and <em>P.purpurea</em> under climate change scenarios.
