[Biomass structure analysis of Atractylodes lancea in different ecological environments].
OBJECTIVE
To study the ecological environments of Atractylodes lancea by biomass structural analysis.


METHODS
Through the scientific investigation in Maoshan, the sampling spots were set up, the relation between growth and ecological environments was researched and the ecological environments of A. lancea were divided as following: the vegetation layer, the shrub layer, the shrub-weed layer and the weed layer. The ramet biomass, height, leaves and coverage of A. lancea were studied.


RESULTS
The several factors (ramet biomass, height, leaves and coverage) showed the regular change. Among maximum, minimum and average, the shrub layer was the biggest, the shrub and weed layer was the second biggest and the vegetation layer and the weed layer was the least.


CONCLUSIONS
A. lancea tends to distribute in the shrub layer and the shrub-weed layer.
