摘要(Abstract):

为明确朝鲜淫羊藿优质药材产区空间分布,通过走访和实地调查,收集朝鲜淫羊藿药材样品和分布信息,基于朝鲜淫羊藿中4种黄酮类化学成分含量,利用GIS技术、最大熵模型(MaxEnt)、地理探测器统计分析方法,绘制朝鲜淫羊藿优质产区分布图,筛选出影响朝鲜淫羊藿分布的主要环境因子,并得出具有统计学意义的回归方程。综合考虑朝鲜淫羊藿中4种主要黄酮类成分含量,该研究结果表明降水量、年降水量变异系数、年平均温度、黏土量等主要环境因子对朝鲜淫羊藿的生长适宜度影响最大。朝鲜淫羊藿优质药材集中分布在吉林省东南部长白山腹地以及辽宁省东北部,其中朝藿定A、朝藿定C含量较高的区域主要分布在吉林省东南部和辽宁省东北部,朝藿定B含量分布较高的区域在辽宁省东部,淫羊藿苷含量较高的区域大部分在辽宁省东北部,少量分布于吉林省东南部。该研究预测了朝鲜淫羊藿气候适宜性分布概况,为合理规划和建立朝鲜淫羊藿规范化种植基地、推广高产优质的优良品种、推进实施中药现代化的进程提供参考。
The study is aimed to clarify the spatial distribution of Epimedium koreanum( Ek) high-quality production areas. Through visiting and field investigation,collecting the distribution information of Ek samples,and based on the four kinds of flavonoids in Ek,the high-quality production areas and distribution of Ek distribution of the main environmental factors were drawn using GIS technology,the maximum entropy model( MaxEnt),geographical detector statistical analysis method,and the statistical significance of regression equation were obtained. Considering the content of 4 main flavonoids in Ek,the results of this study showed that the main environmental factors,such as precipitation,annual precipitation variation coefficient,annual average temperature and clay content exhibited the greatest influence on the growth suitability of Ek. Ek materials quality concentrated distribution in southeastern Jilin province Changbai mountain hinterland and northeastern Liaoning province. Ek with high content of epimedine A and epimedine C are mainly distributed in the southeastern Jilin province and northeastern Liaoning province,Ek with high epimedine B is distributed in eastern Liaoning province; high icariin Ek was found in most area of northeastern Liaoning province,a small amount distributed in the southeast of Jilin province. This study predicted the climate suitability distribution of Ek,and provided reference for the rational planning and establishment of the standardized cultivation base of Ek.
