This research aims to assess the habitat suitability of Michelia crassipes Law based on the species distribution data derived from specimen records and environmental variables through the approach of MaxEnt. The predicted habitat suitability was divided into suitable area and most suitable area according to the selected threshold. National reserve and land use data were used to conduct the analysis of conservation status and human disturbance of suitable habitat. The results show:Compared with topography variables and temperature variables, annual precipitation was the most important variables which influences the habitat suitability. The suitable habitat for Michelia crassipes Law was mainly located in the east area of middle subtropics, between 22 and 30degrees north latitude and between 107 and 120 degrees east longitude. The area of most suitable habitat and suitable habitat were 137000km2 and 270000km2. Guangdong, Guangxi, Hunan, Jiangxi and Fujian share the largest area of suitable habitat. Only 1.9% of the suitable habitats were under the protection of national reserves. Large areas of the suitable and most suitable habitats were left in a state without any protection. Woodland occupy the largest area of the suitable and most suitable habitat. However, human disturbance also occupy big area of suitable and most suitable habitat.
