摘　　要：本文利用多重线性回归的方法得到牛蒡子品质指标的预测模型,利用GIS分析,得到牛蒡子不同品质指标在全国的分布,进而综合利用适宜性评价模型,从而得到牛蒡子适宜性在全国的空间分布,得到牛蒡子不同品质指标在全国的分布。结果表明,影响牛蒡子品质指标的因子主要是7月平均温度和最高温度、年均温、年降水等,全国牛蒡子最适宜分布区主要在东北地区、华南地区,四川云南、西北部分地区等地区,不适宜生长区主要分布在西藏地区、青海省、西北部分地区。Fructus Arctii is the mature fruit of Arctium lappa L. a large biennial herb mainly found in the gullies, the edges of forests, barren hills, and grasslands. In China, it mainly grows in Jilin, Liaoning, Heilongjiang, Zhejiang among others. Most previous studies had focused more on the suitability of growing Fructus Arctii, than its distributions. In this study, we used Multiple Linear Regression Model and GIS to map out the distributions of Fructus Arctii of different properties. With the help of the suitability evaluation model, we have produced a suitability distribution map for the herb. Results show that the major factors affecting the growth of Fructus Arctii are the averaged and maximum temperatures of July, annual mean temperature, and annual mean precipitation. The most desirable growing areas are the northeast and southern part of the country, Sichuan, Yunnan, and some areas in the northwest. A number of areas, including Tibet, Qinghai, and some areas in the northwest of the country are not desirable for growing the herb.
