摘要
九顶山是青藏高原向四川盆地过渡的山地之一,山体高大,垂直生境变化明显,孕育了丰富的药用植物.本次调查获得药用资源植物 184种,其中以多年生植物为主 (51. 1% ),其次为矮小高位芽植物 (15. 8% )和中高位芽植物(10. 9% ),大高位芽植物、小高位芽植物和一年生植物比例相对较小,它们分属 72科,种数较多的科依次是菊科、蔷薇科、唇形科、伞形科、毛茛科、禾本科、豆科、百合科、蓼科和芸香科,单种科比较多,约有 40余科.在野外调查的基础上分析了九顶山药用资源的生态学特征、资源特点,并根据调查中发现的问题提出了保护和合理开发药用植物资源的措施.
The Jiuding Mt.is one of the transition Mts. From the Qingzang Plateau to the Sichuan Basin, It is very high and the vertical environments change rapidly, so it has abundant medical plants. We have found 184 species medical plants in this investigation,the chief types are Hemicryptophytes and Geophytes(51.1%),the second types are Nanophanerophyte(15.8%) and Mesophanerophyte(10.9%),the proportion of Megaphanerophyte,Microphanerophyte and Annual plants are lower. These species belong to 72 families,some families including more species,such as Composite family, Rose family, Labiaal family, Umbellliferous family, Ranunculi family, Grass family, Bean or Pea family, Polygonatum family, Polygoum family and Rutin family, but nearly 40 famlies including only one species. This article analyses the ecological characteristics and distribution feature of medical plants based on wild investigation in the Jiuding Mt. And we have put forward countmeasures to protect and rationaly utilize these medical plants according to the problems which we have found from this investigation.
