Comparative study on distribution of Polygoni Multiflori Radix based on different methods / 中国中药杂志

ABSTRACT

In recent years,with deepening research on the division of traditional Chinese medicine,the application of new technologies and new methods have provided support for the division of traditional Chinese medicine. Some relevant scholars have carried out researches on the distribution of some Chinese herbal medicines based on different methods. In this paper,for the same kind of Chinese herbal medicine under different data conditions,we studied the distribution of Polygoni Multiflori Radix by different methods such as qualitative description,similar ecological environment and niche model,and compared the similarities and differences between the distribution results of the same Chinese medicine resources based on different data and methods. The results showed that with the restriction of the researcher's understanding of Chinese herbal medicines and related background data,the zoning results were also in various forms,and there might also be some differences between different zoning results. But in the macroscopic layer,they could reflect the distribution range of Chinese herbal medicines,and they have certain application values to some extent. For example,the study focused on the ancient and modern data and found that with the continuous enrichment of data and information,the understanding of the distribution of Polygoni Multiflori Radix gradually expanded from the southeast coast to the central and southwestern regions to the northwest.But the number of Polygoni Multiflori Radix in the western and northern regions is relatively small than the southeastern regions. The results of relevant zoning can provide scientific basis for carrying out the rational cultivation of Polygoni Multiflori Radix.
