摘要
对西藏、青海、甘肃、四川、云南等省区的桃儿七资源进行调查。结果表明,桃儿七主要分布于我国中部从陕西太白山区由北向南沿横断山脉两侧的中高山及青藏高原地带,适生生境以海拔1 5004 500 m的沟谷湿润林下到高原面上较为干旱的矮小灌丛植被为主,单纯的高山草甸分布密度相对较小;光照、水分、土壤、温度、海拔等从不同的角度对桃儿七的分布和生长、资源蕴藏量都有着明显的影响。采取文献调查、走访调查、样方调查及市场调查等方法。作为藏药＂小叶莲＂（果实）和鬼臼毒素提取原料的地下部分的市场需求增长迅速,采挖地下部分的＂鬼臼＂是导致近年桃儿七资源急剧减少的主要原因。建议一方面应加强对＂鬼臼＂的合理限量采挖管理,同时应开展桃儿七资源利用价值的评价,并加快发展桃儿七的栽培生产。
The resource of Sinopodophyllum emodi in Tibet,Qinghai,Gansu,Sichuan and Yunnan province were surveyed by the ways of documents,interview,quadrat and market investigation.The results indicated that S.emodi were mainly distributed in central part from Taibai Shan of Shanxi province along the middle and high mountain on either side of Hengduan mountain which from north to south and in Tibetan plateau of China,the suitable eco-environment of S.emodi was dominated by valleys,wet forests and low bush-woods vegetation which comparatively dry on plateau with the altitude focused on 1 500-4 500 meters,and the distribution density of simple alpine meadow was relatively lower.Illumination,water,soil,temperature and altitude had significant influences on the growth,distribution and reserves of S.emodi from different angles.In recent years,there was sharp increase of market requirement in Xiaoyelian（fruit） which were used in Tibetan medicine and the underground part which was used for the extraction of podophyllotoxin,excess collection of the underground part was the primary cause of the rapid decreasing resource of S.emodi.It is suggested that the management of rational collection should be strengthen and the development of culturing and production should be meanwhile accelerated.
