英文摘要	Pinus tabulaeformis, as an endemic species in China, is one of the main tree species for afforestation. For rational cultivation planning and conservation, it is necessary to understand the geographical boundaries and the ecological characteristics of P. tabulaeformis, and to explore its priority afforestation areas. In this study, maximum entropy modeling (MaxEnt) was used to identify and prioritize suitable habitats of P. tabulaeformis, based on 13 climatic variables and GlobCover 2009 data. The results show that the MaxEnt model performs better than random prediction, with an average test area under the curve (AUC) value of 0.93 (0.91-0.94). Precipitation of wettest month (PWM), annual biotemperature (ABT), mean temperature of the coldest month (MTCM), annual mean temperature (AMT), precipitation of driest month (PDM), coldness index (CI), annual precipitation (AP), and mean temperature of the warmest month (MTWM) are identified as dominant variables which explain 94.6% of variability the geographical distribution of P. tabulaeformis. Climatic conditions of P. tabulaeformis in the core area of its distribution are as follows: PWM, 100-246 mm; ABT, 3.0-4.7 degrees C; MTCM, 20.2 to 1.1 degrees C; AMT, 2.9-14.7 degrees C; PDM, 2-11 mm; CI, 49.4-0 degrees C; AP, 431-1122 mm; and MTWM, 19.6-31.2 degrees C. The suitable areas for afforestation are 2.6 x 10(4) km(2) (patches with an area >1 km(2)), 1.6 x 10(4) km(2) (patches with an area >10 km(2)), and 1.2 x 10(4) km(2) (patches with an area >100 km(2)), which are mainly located in north Shaanxi, south Ningxia, and the middle of Gansu and Liaoning provinces with serious landscape fragmentation caused by human agricultural activities. Our simulation results can improve our understanding of the geographical and ecological characteristics of P. tabulaeformis and provide prediction of priority areas for afforestation of this species under current and future climate change scenarios in China.
