Abstract: The identical ecological distributions suitable for the planting in Hubei Province of the superior varieties of Cunninghamia lanceolata introduced from the mountainous region surrounding Sichuan basin were predicted by using MaxEnt model and ArcGIS software, and the dominant climatic factors affecting the growth were analyzed and determined. The results showed that the MaxEnt model had a high prediction accuracy for the same ecological region suitable for introduction of the superior varieties of Cunninghamia lanceolata, and the mean AUC of the training samples and tested samples predicted by the model was greater than 0.8. The suitable regions for this species covered an area of 5204295 hectares, mainly distributed in Suixian, Dongbao, Duodao, Shayang, Jingzhou, Shashi, Jiangling, Songzi, Gongan and Shishou in central Hubei as well as Yichang, Enshi, Xiangyang, Shiyan and Shenlongjia in western Hubei. Daily average solar radiation and accumulated temperature ≥10℃ were the dominant climatic factors that affected the distribution of suitable planting areas for the superior varieties of Cunninghamia lanceolata introduced from the mountainous areas around the basin of Sichuan province.
