| 中文摘要:为提高药材黄花蒿Artemisia annua的质量和产量，基于396个黄花蒿分布点及35个环境数据，采用最大熵模型（MaxEnt）预测黄花蒿在中国的生态适宜区，应用R语言构建青蒿素含量与环境因子的关系模型，用ArcGIS软件预测青蒿素空间分布以进行黄花蒿生产区划。结果表明，黄花蒿最适宜区主要分布于四川省东部、重庆市西部、贵州省、广西壮族自治区、云南省西部、湖北省东部等。影响黄花蒿地理分布的生态因子主要是气候因子和土壤因子，其贡献率之和分别达76.6%和10.9%。黄花蒿中青蒿素含量较高（>0.7%）的区域主要包括重庆、四川、贵州、广西、云南和湖南等省（区、市），可作为高品质黄花蒿的首选栽培地区；长江以北地区的青蒿素含量稍低（0.5%~0.7%），可作为黄花蒿的扩种区；处于沿海地区的广东、福建和江西等省的青蒿素含量最低（<0.3%），不建议在这些地区进行大规模引种栽培。 |

| Abstract:To improve the quality and yield of medicinal plant Artemisia annua, the ecologically suitable area in China was predicted by the maximum entropy model (MaxEnt) based on 396 sampling points and 35 environmental variables. The relationship model about the artemisinin content and environmental factors was established by R language, and then the production regionalization of A. annua was performed by ArcGIS based on the space distribution of artemisinin content. The results showed that the most suitable areas of A. annua were mainly distributed in the area of eastern Sichuan, Guangxi, western Yunnan, Guizhou, eastern Hubei,and western Chongqing. The ecological factors mainly affecting the geographical distribution of A. annua were the climate and soil, and the total contribution rates were 76.6% and 10.9% respectively. The regions with high content of artemisinin (>0.7%) were Chongqing, Sichuan, Guizhou, Guangxi, Yunnan and Hunan provinces, which could be the preferred cultivation areas for high-quality A. annua. The regions with lower artemisinin content (0.5%-0.7%) were widely distributed in north of the Yangtze River, which could be used as the expanding area of A. annua. The coastal areas such as Guangdong, Fujian and Jiangxi provinces, where the artemisinin content (<0.3%) was low, were not recommended as the large-scale introduction and cultivation. |
