ABSTRACT
<p><b>OBJECTIVE</b>To study the biomass structure of Epimedium acuminatum Franch in the different ecological environments for the development and protection.</p><p><b>METHOD</b>Through the scientific investigation in four typical habitats, the sampling spots were set up, the functional modules' biomass structure and relationship of E. acuminatum were researched.</p><p><b>RESULT</b>The average of rhizome, as the largest biomass, and the average total biomass had the same pattern: the open areas of forest edge > shrub lumber > shrub-weed > stream drains. The ratio of the functional modules' biomass had different rates under different habitat conditions. By analyzing and combining investigation, the aerial part of E. acuminatum in the shrub-weed were comparative advantage, and the roots of nutrient accumulation of E. acuminatum in the open areas of forest edge were the highest efficient. Under different ecological condition, the distribution of water metabolism was different strategies.</p><p><b>CONCLUSION</b>In the open areas of forest edge, E. acuminatum growing well, followed by shrub-weed. These two habitats are the ideal ecological environments while the rhizome or the whole plant used as medicine, but also the protection of E. acuminatum.</p>
