针对青蒿种植的迫切需求，通过查阅文献资料，得到了我国青蒿中青蒿素的含量。本文运用统计分析方法，分析了农业作物产量与生态因子的关系。利用ArcGIS软件分析了中国农业气候适宜等级分布。结果表明：第一，中国的ARTC存在显著差异，南方地区的ARTC较高。我国北方大部分地区气候条件不适宜青蒿生长，在北方纬度34度以上的地区青蒿生长的ARTC低于0.2%。当ART生长在北纬34度以下，东经100度到120度之间时，ARTC较高，ART生长良好。其次，亚热带是青蒿生长的最适气候带，在亚热带地区青蒿生长良好，青蒿素转化率高于0.5%。温度、日照时数和降雨量是影响青蒿生长和青蒿素积累的主要生态因子。年平均气温在13.9 ℃ ~ 22 ℃之间，日照时数在853 h ~ 1507 h之间，降雨量在814 mm ~ 1518 mm之间，是ARTC积累的最佳气候条件。温度在13 ℃ ~ 29 ℃之间，降雨量在600 mm ~ 1300 mm之间，是青蒿生长的最佳气候条件。（4）广西西北部、四川、贵州、云南东部、重庆南部和湖南西部等地，是青蒿生长和青蒿素积累的适宜气候。湖北、安徽、江苏等省南部也有适宜青蒿生长的气候区。
At the urgent request of Artemisia annua (ART) planting, the paper gets artemisinin content (ARTC) of ART in China from literatures. The paper analyses the relationships between ARTC and ecological factors by statistical analytical methods. The paper also analyses the climate suitable rank distribution of ARTC in China by ArcGIS. The results display that first, ARTC is significantly different in China, that ART from the south regions ARTC is higher. Greatest north parts of China have not suitable climate for the growing of ART and the ARTC is lower than 0.2%, when ART grows above the 34th degree of northern latitude. ARTC is higher and ART grows well, when ART grows under the 34 degrees N and grows at the areas between 100 degrees E and 120 degrees E. Second, subtropical zone is the best suitable climate zone for the growing of ART. ART grows well and ARTC is higher than 0.5%, when ART grows in the subtropical zone. Third, temperature, sunshine duration and rainfall are the main ecological factors that affect the growth of ART and the accumulation of ARTC. That the year temperature between 13.9 degrees C and 22 degrees C, sunshine duration between 853 h and 1507 h, rainfall between 814 mm and 1518 mm, is the best climate for the accumulation of ARTC. Temperature between 13 degrees C and 29 degrees C, rainfall between 600 mm and 1300 mm is the best climate for the growth of ART. Fourth, in northwest of Guangxi, eastern of Sichuan, Guizhou and Yunnan provinces, south Chongqing and west Hunan Province, there are suitable climate for the growth of Artemisia and for the accumulating of ARTC. There are also some suitable climate areas for the growing of artemisia in the south of Hubei, Anhui and Jiangsu provinces.
