摘　　要：目的:通过生物量结构分析研究茅山苍术的生态环境。方法:通过苍术道地产区茅山的野外实地调查,建立样方,探讨了苍术在茅山的生长状况和生态环境的关系,将苍术的生长环境分成乔木林,灌木林,灌木杂草林和杂草。研究4种生态环境下苍术的株生物量,株高,茎粗,叶片数和盖度。结果:茅山苍术在各项指标的最大值和最小值以及平均值的变化是规律的,均表现为灌木丛中苍术的株生物量,株高,茎粗,叶片数,冠幅最大,灌木杂草林次之,杂草第三,乔木林最差。结论:茅山苍术更趋向于分布于灌木丛和灌木杂草丛中。Objective： To study the ecological environments of Atractylodes lancea by biomass structural analysis. Method： 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 ofA. lancea were studied. Result： 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. Conclusion：A, lancea tends to distribute in the shrub layer and the shrub-weed layer.
