中药野生资源分布规律初探

目的 为总体研究中药野生资源的分布规律提供可靠依据。方法 利用《中国高等植物》关于植物分布的图片和文字资料，对其中主要的药用植物资源的野生分布区的形状、面积等方面进行初步的研究。结果 选取的常用药用植物中，70%以上符合带状分布；7.87%的药用植物分布省区在5个以下，71.63%的药用植物分布达到或超过10个省区；常用中药的分布区域主要集中于甘肃、陕西、河南、四川、山东等省及江淮流域和江南地区。结论 中药野生资源多呈带状分布，多数为广布种，常用中药主产于汉民族的主要分布区。

Preliminary Study on Distribution Characteristics of Wild Resources of Traditional Chinese Medicine

Objective To provide reliable evidence for the overall study of distribution characteristics of wild resources of traditional Chinese medicine (TCM). Methods The shape and size of distribution areas for wide resources of important medicinal plants were preliminarily studied according to images and text information in High Plants of China. Results More than 70% of common medicinal plants have a zonal distribution. And 7.87% of medicinal plants are found in less than five provinces; 71.63% of medicinal plants are found in more than 10 provinces. The main distribution areas of common TCMs include Gansu, Shaanxi, Henan, Sichuan, and Shandong provinces, as well as Yangtze and Huaihe River basins and south area of Yangtze River. Conclusion Most wild resources of TCM have a zonal distribution and are widespread in China. Most of common TCMs are from the distribution areas of Chinese Han population.
