赫章县野生重楼资源的种类及分布

Species and Distribution of Wild Paris Resources in Hezhang County

为给重楼属药用植物资源的保护和合理开发利用提供依据,采用实地调查与查阅资料相结合的方法,对贵州省赫章县25个乡镇的野生重楼属植物资源种类、分布区域及资源现状进行调查。结果表明：在25个乡镇中只有9个乡镇有野生重楼属植物分布,且个体多在8株以内;主要分布在海拔1600-2100m的针阔混交林下,种类有狭叶重楼、七叶一枝花、滇重楼、毛重楼及黑籽重楼等5种,以狭叶重楼和七叶一枝花的数量居多;首次发现黑籽重楼分布。赫章海拔1 600m以上、水资源和腐殖层丰富的针阔混交林下较适宜重楼属植物生长,但野生重楼资源减少严重,人工种植迫在眉睫,需对野生资源进行合理保护。

To provide the basis for the protection and rational utilization of Paris resources,the species,distribution and current status of wild Paris resources in Hezhang County of Guizhou Province were surveyed by field investigation and referring data resources in 25 towns and villages in Hezhang County of Guizhou Province,then the collected samples.Results：Wild Paris resources were found（eight individuals at most）in nine towns and villages,which were at an elevation of 1 600-2 100 m in theropencedrymion.They belonged to the following five species,P.polyphylla Smith var.stenophylla Franch,P.polyphyllavar.chinensis,P.polyphyllavar.yunnanensis and P.mairei,P.thibeticaFranch,the first two of which took the largest proportion,and P.thibetica Franch was firstly found.The theropencedrymion in Hezhang,with an elevation of over 1 600 m,rich water resources and humus layers,was suitable for the growth of Paris.Because of the severe decrement of wild Paris resources,artificial cultivation and rational protection of wild Paris resources became extremely urgent.
