以四川江油为道地基点县,运用《中药材产地适宜性分析地理信息系统》(TCMGIS-I),分析了附子的全国适宜产地。结果表明按附子药材生长所需要的气候、土壤条件分析,除四川江油县等为附子的传统产区外,全国共有四川、陕西、贵州、湖南、湖北、甘肃、云南、广西、江西、安徽等10个省区的336个县市为附子适宜产区,适宜产区面积总和为294057.69km2。附子的次适宜产区和适宜产区面积大致相等。附子适宜区分析结果覆盖了第3次全国中药资源普查记载的95%以上的区域,同时还分析预测出贵州、江西等普查没有记载的区域,为引种栽培提供了依据,同时也进一步验证了TCMGIS-Ⅰ系统的科学性和可靠性。通过附子产地适宜性分析发现土壤可能是影响附子分布的主导因素。
Taking Sichuan Jiangyou as a base point counties, using TCMGIS-I to analyze the suitability of aconite in the country. The results showed that according to the climate and soil conditions needed for the growth of aconite medicinal plants, Sichuan, Shaanxi, Guizhou, Hunan, Hubei, Gansu, Yunnan, Guangxi, Jiangxi and Anhui all except the traditional producing areas of Aconite of Sichuan Jiangyou County 336 counties and cities in 10 provinces and autonomous regions are suitable aconite producing areas, and the total area of suitable producing areas is 294057.69km2. Aconite sub-suitable producing areas and suitable for producing area roughly equal. The results of the analysis of aconite suitable area covered more than 95% of the area recorded in the 3rd National Resource Survey of Chinese Materia Medica, and also analyzed and predicted the areas not recorded in the census of Guizhou and Jiangxi so as to provide a basis for introduction and cultivation. At the same time, the results of TCMGIS -Ⅰ system of science and reliability. Through the analysis of the origin of aconite, we found that soil may be the dominant factor that affects the distribution of aconite.
