【摘要】 目的:通过种群构件生物量的分析,研究粗毛淫羊藿在不同生境条件下的变化规律,为粗毛淫羊藿的开发与保护提供依据。方法:在灌木杂草丛、林缘旷地、乔灌木林、沟渠溪边4种粗毛淫羊藿典型生境条件下,分别设置样方,研究4种生境下植株各功能构件生物量结构及其生物量比率。结果:粗毛淫羊藿根茎生物量最大,其平均值与总生物量的平均值具有相同的规律:林缘旷地>乔灌木林>灌木杂草丛>沟渠溪边;根、叶片、叶柄生物量的平均值没有相同的规律。不同生境条件下各功能构件的生物量比率不同,通过分析并结合实地调查情况认为,粗毛淫羊藿地上部分,在灌木杂草丛生境中比较优势;在林缘旷地生境中根茎的营养积累效率最高。此外,粗毛淫羊藿在不同生境条件下,对水分代谢的分配策略不相同:其中在沟渠溪边生境中粗毛淫羊藿的生物代谢比较旺盛。结论:林缘旷地中的粗毛淫羊藿长势良好,其次是灌木杂草丛,这两种生境是粗毛淫羊藿根茎入药或全株入药理想的生境,也是进行保护时的首选生态环境条件。更多还原

【Abstract】 Objective:By biomass structural analysis, to study Epimedium. acuminatum Franch in the different ecological environments for the development and protection. Method: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. Result:The average of rhizome, as the largest biomass, and the average total biomass have the same pattern:the open areas of forest edge >shrub lumber >shrub-weed >stream drains. The ratio of the functional modules’ biomass, which can better reflect biomass distribution relationship of the various components, has 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 efficiency. Under different ecological condition, the distribution of water metabolism is different strategies. Conclusion: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 .更多还原
