[Studies on investigation and utilization of medicinal plant resources for sustainable development in Guizhou, China].
OBJECTIVE
To gain a clear idea of the resources of medicinal plants and their pharmaceutical identification in Guizhou, China, and to conserve, develop, and uilize them effectively.


METHODS
Investigation on the spot with a statistical analysis. The technical route is "Investigation and identification-->Conservation and development-->Method, technology and ways for protection, propagation and utilization-->GAP cultivated pilot and assessment of medicinal materials and their products-->Comprehensive evaluation and results".


RESULTS
According to the incomplete statistics, there are 3924 varieties of medicinal materials from plants, accounting for 91.47% of the total in Guizhou. Among them there are 275 families, 1384 genera and 2987 species of vascular bundle plants, accounting for 43.1% of all species. There are 200 species of pteridophyta and 2802 spermatophyta.


CONCLUSIONS
Investigation of wild medicine species has been proceeded, as well as introduction and research of their propagation techniques and production. Guizhou is rich in medicinal plant resources. However, their species and population are reducing progressively. Effective measures must be taken to protect the germ plasma resources and put them into rational uses for the utilization and sustainable development. Rare and endemic medicine species must be introduced for conservation, propagation and realization of GAP pilot cultivation. Resources must be used in an economical way and products must be made with a high technological content.
