Abstract:
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 5004 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.
