摘要 At present, taxol is an internationally acknowledged drug with a unique anticancer activity in the world and mainly come from Taxus plants, these plants have 12 species, all of which have been listed as endangered tree species and protected by the countries concerned. But available wild Taxus plants resources are rather rare, so it is very urgent to strengthen introduction and cultivation of Taxus plants to meet people''s demand for taxol. According to the ecological similarity of growth of Taxus plants predict suitable areas in the whole world, which could put forward rational suggestions for introduction and planning production layout of plants. A geographic information system for global medicinal plants (GMPGIS) was developed by Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences independently, and using GMPGIS analyzed in detail the potential ecological suitable areas of Taxus plants. Ecological range of Taxus wallichiana var. chinensis, Taxus wallichiana var. mairei, Taxus baccata, Taxus brevifolia and Taxus wallichiana covered a wide field, and had larger suitable area in the northern and southern hemispheres; Taxus cuspidate mainly distributed in the northern hemisphere, and only scattered in the southern hemisphere; Taxus canadensis, Taxus floridana and Taxus cuspidata var. nana only distributed in the northern hemisphere, and the latter two prediction areas are relatively less areas; Taxus fauna, Taxus globosa and Taxus sumatrana grew up in relatively strict environment, belong to the niche species, scattered distribution and the distribution of the areas are rare. This research would exert an important promoting effect on the cultivation of Taxus plants and the escalation of abundance to guarantee the sufficient supply of raw materials for taxol production. Finally, this paper summarized the research on the ecological quality and resource conservation of Taxus plants, to provide the reference for scientific introduction and cultivation of Taxus plants.
