RESUMO
The suitable production area can guarantee the quality of Dai medicine， but the research on the suitable ecological factors and suitable production area of plant Dai medicine is relatively scarce at present. In this study， gmpgis was used to analyze the ecological suitability of Dai medicine in China. For the first time， the range of ecological factors and main soil types in the main distribution areas of Dai medicine were extracted， such as annual average temperature of 8.6-23.7 ℃， annual average precipitation of 1212-1881 mm， annual average sunshine of 149.7-157.4 W·m-2， the main soil types are strong eluvial soil， alluvial soil， high activity strong acid soil， etc. Based on 179 sampling points， through the analysis of ecological similarity， the largest ecological similarity area of plant Dai medicine in the world was obtained， mainly including China， Brazil， the United States， Myanmar， Laos and other countries. In China， it is mainly concentrated in the West and south of Yunnan， including Xishuangbanna Dai Autonomous Prefecture， Dehong Dai Jingpo Autonomous Prefecture， Pu'er City， Baoshan City and Lincang City， which are suitable for cultivation. In addition， by analyzing the current situation of Dai medicine industry， this paper summarizes the problems such as the lack of talents， the decreasing of Dai medicine resources， the limitation of cultural heritage， and the weakness of scientific research， and puts forward strategies such as training high-quality talents of Dai medicine， the investigation and protection of Dai medicine resources， promoting the collection and arrangement of Dai medicine data and ancient books， and strengthening the basic and applied research of Dai medicine Enter the development of Dai medicine. This study provides a basis for guiding the rational layout， introduction and breeding of plant Dai medicine production base， and lays a foundation for the scientific and standardized production of high-quality Dai medicine.
RESUMO
Appropriate producing areas can guarantee the quality of Tibetan medicine, but research on the suitable ecological factors and suitable producing areas of Tibetan medicinal plants is scarce. This paper used the Geographic Information System for Global Medicinal Plants(GMPGIS) to analyze the ecological suitability of Tibetan medicinal plants nationwide. For the first time, the range of ecological factors and main soil types of Tibetan medicinal plants were extracted, such as the average annual temperature-19.4-24.2 ℃, annual average precipitation 17-4 088 mm, annual average sunshine 124.2-171.6 W·m~(-2). The main soil types were black calcareous soil, thin layer soil, chestnut soil and so on. Based on 337 sampling points, the largest ecological similarity area of Tibetan medicine across the country was obtained through ecological similarity analysis. In addition to Tibet and Qinghai provinces and Tibetan Autonomous Prefectures in Sichuan, Gansu, and Yunnan provinces, Jiuquan city and Linxia county in Gansu province, Panzhihua and Ya'an in Sichuan province, and Xinjiang, Inner Mongolia, and Shanxi provinces also had larger suitable cultivation areas. In addition, by analyzing the current situation of Tibetan medicine industry, the research pointed out that there were some problems such as unreasonable development and utilization of resources, lack of standards and norms, weak basic research and imperfect industrial system, and made corresponding countermeasures for sustainable development of resources, formulation of standards and specifications, promotion of medicine through science and technology, expansion of domestic and foreign markets, etc. This study provided the basis for guiding the rational layout of production bases, introduction and breeding of plant Tibetan medicine nationwide, laying the foundation for the scientific and standardized production of high-quality Tibetan medicine, clarifying the development direction of Tibetan medicine industry, and providing ideas for the development strategy of Tibetan medicine and other national medicine industry.
