Objective: To Investigate the distribution of Atractylodes lancea at Maoshan regions.
Methods: To combine the plot sampling with GIS technology in the analysis of distribution and its factors.
Results: The biomass of Atractylodes lancea was related to the growth of Ouercus serrata var. brevipetiolata, slope and humidity. The distribution of Atractylodes lancea which was less in north Maoshen region, most in south region, least in middle region.
Conclusion: The main factor of distributing sintuation is the human beings. The leading factors in the biomass of Atractylodes lancea are Ouercus serrata var. brevipetiolata and slope.
