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。
In this paper, the multiple linear regression method was used to get the prediction model of Arctium lappa quality index. By GIS analysis, the distribution of different Arctium lappa quality indicators in the country was obtained, and then the suitability evaluation model was comprehensively used to obtain the spatial distribution of Arctium lappa suitable in the whole country , Get the different quality indicators Arctium distribution in the country. The results showed that the main factors influencing the quality of Arctium lappa were July average temperature and maximum temperature, annual average temperature and annual precipitation. The most suitable distribution areas of Arctium lappa were mainly in Northeast China, South China, Yunnan and parts of Northwest China Areas, unfit for growth areas are mainly distributed in Tibet, Qinghai, parts of the northwest.
