In this research, we collected information of eighty nine sampling points of Isatidis Radix nationwide through data query and field survey, and the medicinal component contents of samples were determined by HPLC. By using Maxent Model and ArcGIS, along with ecological factor data, the national habitat suitability distribution of Isatidis Radix was predicted. R-language was adopted to establish a model of the relationship between the medicinal component contents and ecological factors. The medicinal quality was divided by ArcGIS grid computing. The results indicated that the three main ecological factors affecting the distribution of Isatidis Radix were precipitation in the driest season, mean annual temperature and mean temperature in the wet season. The suitable cultivation region of Isatidis Radix is mainly distributed in the north of China, but the medicinal quality is quite different, Isatidis Radix in Xinjiang province has higher medicinal quality. This study provides a reference for rational selection of planting areas of Isatidis Radix.
本研究通过数据查询和实地调查收集了全国89个板蓝根采样点的信息，并采用高效液相色谱法测定了样品的药用成分含量。利用Maxent模型和ArcGIS，结合生态因子数据，预测了板蓝根在全国的适生区分布。采用R语言建立了药用成分含量与生态因子之间的关系模型。通过ArcGIS网格计算划分了药材质量等级。结果表明，影响板蓝根分布的三个主要生态因子是最干旱季节降水量、年平均气温和雨季平均气温。板蓝根适宜种植区主要分布在中国北方，但药材质量差异较大，新疆的板蓝根药材质量较高。本研究为合理选择板蓝根种植区域提供了参考。
