基于不同方法的何首乌分布区划研究

Comparative study on distribution of Polygoni Multiflori Radix based on different methods

近年来随着中药区划研究的不断深入,新技术、新方法的应用为中药区划提供了支持,相关学者基于不同方法开展了一系列的中药分布区划研究。该文以何首乌为例在不同数据资料条件下,利用定性描述、生态环境相似、生态位模型等不同方法进行何首乌分布区划研究,对比基于不同数据信息和方法进行同种中药资源分布区划结果的异同性。结果显示:受研究者对中药材分布范围认知程度、相关背景数据资料的限制,中药材的分布区划方法可有多种方式,其区划结果形式也多种多样、不同区划结果之间也存在一定的差异性。但在不同程度均能反映出中药材的分布范围情况,均具有一定的应用价值。该文对古代和近现代的资料研究发现,随着数据信息资料的不断丰富,人们对何首乌分布的认知范围逐渐扩大,由东南沿海、逐渐扩大到中部和西南地区、再到西北地区;但是何首乌在西部和北部地区的数量,相对东南部地区的较少,相关区划结果在不同程度上均可为何首乌的引种栽培提供参考。

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.
