We simulated global suitable distribution areas of L. kaempferi under current and future climates, using different representative concentration pathway (RCP) scenarios, to evaluate the main factors affecting its geographical distribution. The results showed that under current climate conditions the suitable distribution areas of L. kaempferi are concentrated in Europe and Asia, followed by North America. The "Germany-Sweden-Britain" (19.42% of the total worldwide area) and "China-Japan-North Korea" (43.11%) regions are the cores for L. kaempferi distribution. The suitable distribution area for L. kaempferi is large in China (33.75% of the total area). The suitable distribution areas in Asia, Europe, and China decreased and shifted northward in the RCP scenarios. The main climatic factors affecting the distribution of L. kaempferi were the annual mean temperature, mean temperature of the coldest quarter, annual mean precipitation, and precipitation in the driest month. L. kaempferi could adapt or move to higher latitudes/altitudes to cope with climate change. Our results contribute to the introduction, cultivation, and management of L. kaempferi and potentially of other deciduous gymnosperms.
