- 摘 要:通过野外实地调查,研究了陕南秦巴山区不同立地条件下药用植物物种多样性变化和不同生活型物种多样性特征。结果表明:从生活型来看,药用植物乔木层、灌木层、草本层物种多样性指数及物种多样性指数和均表现为:北部山地区>东部山地区>南部浅山丘陵区;均匀度指数灌木层和草本层均表现为:北部山地区>东部山地区>南部浅山丘陵区,乔木层则表现:东部山地区>北部山地区>南部浅山区。总体而言,不同立地条件下药用植物物种多样性表现:北部山地区>东部山地区>南部浅山丘陵区,即表现海拔越高物种多样性越高的规律。各立地条件下生活型药用植物物种多样性略有不同,南部浅山丘陵区表现为:草本层>乔木层>灌木层;东部和北部山地区表现为:草本层>灌木层>乔木层。草本层更具有多变性,能适应不同的生境变化,其多样性最高。

- Abstract:In this paper 12 sample plots were investigated to determine the types of medicinal plant and diversity community species in Yang County through field survey.The results showed that from biotype,medicinal plant tree layer,shrub layer and herb layer,species diversity index and total species diversity index performed that northern mountain region>eastern mountain region>southern area with shallow hilly land.Evenness index in shrub layer and herb layer showed that northern mountain region>eastern mountain region>southern area with shallow hilly land.Tree layer showed that eastern mountain region>northern mountain region>southern area with shallow hilly land.In general,the medicinal plant species diversity performance under different site conditions showed that northern mountain region>eastern mountain region>southern area with shallow hilly land which means the higher the elevation of the higher species diversity.The medicinal plant diversities were slightly diverse in different site conditions,the southern area with shallow hilly land showed that herb layer>tree layer>shrub layer,which herb layer>shrub layer>tree layer in the northern and eastern region.Herb layer showed more polytropic that can adapt the variation of different biotope.
