5 Conclusions
High-quality TCM should be planted in specific natural conditions and ecological environments. Therefore, the prediction and suitability evaluation of potential distribution areas of TCM have important guiding significance for scientific planning of wild tending areas. This study analyzed the change in the distribution range of T. chinense in China under future climate and land use changes. Although the stable areas suitable for the growth of T. chinense under climate change are still large, the grassland in this area is decreasing year by year, which may pose a threat to the population of T. chinense in China. To solve the contradiction between the supply and demand ofT. chinense , we used ZONATION software and hot spot analysis to determine the counties in China that are suitable for the wild tending of T. chinense . This will provide a scientific and effective reference for the relevant government departments at all levels when planning the wild tending area of T. chinense , and also provide an important reference for the diversity protection, restoration and sustainable development of other wild medicinal species. From the macro-view, the distribution of T. chinense under the future climate and land use change was explored. In future, we will continue to explore other factors that affect the change of the wild population structure of T. chinense , and find the reasons for the change of distribution pattern from a microscopic perspective. We should strengthen the research on the correlation between the content of effective components of T. chinense and environmental factors and hosts, and construct the spatial distribution layer of effective components of T. chinense , to provide a more accurate and scientific theoretical basis for more proper planning of the wild tending areas of T. chinense population.
