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.
