以内蒙古杭锦旗为“梁外”甘草的道地基点县,运用《中药材产地适宜性分析地理信息系统》(TCMGIS-Ⅰ),分析了乌拉尔甘草在全国的生态适宜区。结果表明以生产“梁外”甘草药材为目标的乌拉尔甘草的生态适宜区,除杭锦旗等“梁外”甘草传统产区外,还包括内蒙古、河北、山西、陕西、甘肃、新疆等6个省区的118个县市,生态适宜区(相似系数:SI≥90%)面积总和为304832·20km2。次适宜分布区和适宜分布区面积大致相等。一般适宜区面积是适宜区面积的4倍左右。分析结果比第3次全国中药资源普查记载的省份增加了吉林省东部和北京周边地区,为下次资源普查和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。通过乌拉尔甘草生态适宜性分析发现土壤和植被类型可能是影响甘草分布的主导因素。
Taking Hangjin Banner in Inner Mongolia as the base point county of “Leung Bei” licorice, the paper analyzed the ecological suitable area of Ural licorice in China using “TCMGIS-Ⅰ”. The results showed that the ecological suitable area of Ural Licorice which is targeted at the production of “Beam” licorice herbs includes 6 traditional licorice producing areas such as Hangjinqi and Bei Liang, including Inner Mongolia, Hebei, Shanxi, Shaanxi, Gansu and Xinjiang 118 counties in provinces and autonomous regions, ecological suitable area (similarity coefficient: SI ≥ 90%), the total area of 304832.20km2. Sub-suitable distribution area and suitable distribution area roughly equal. Generally suitable for the area is suitable for the area of about 4 times. The results of the analysis provided a basis for the next census and introduction of resources than the provinces recorded in the 3rd National Census of Resources of Chinese Medicine in the eastern part of Jilin Province and surrounding areas of Beijing and further verified the scientificness and reliability of the TCMGIS-Ⅰ system . According to the ecological suitability analysis of Ural Licorice, it was found that soil and vegetation types may be the dominant factors affecting the distribution of licorice.
