Growth suitability of Magnolia officinalis based on habitat suitability

OBJECTIVE To study the growth suitability of Magnolia officinalis on the basis of investigation on the correlation between its growth and ecological factors， and to provide scientific basis for determining the suitable planting region of Magnolia officinalis in China. METHODS Based on the investigation of 43 sampling points of Magnolia officinalis， the ecological factors affecting its growth was calculated by Maxent. The geographic information system(GIS) was applied to assess the growth suitability rank dividing of Magnolia officinalis in China. RESULTS Precipitation of October， altitude， September precipitation， precipitation in July is the main ecological factors that influencing the growth of Magnolia officinalis. The habitat suitability values of Magnolia officinalis in Southwest of Hubei province and Eastern Chongqing is highest. CONCLUSION Hubei and Chongqing are the suitable planting areas of Magnoliae officinalis.
