黄花蒿资源品质（青蒿素含量）具有显著的生态地域性，可能是黄花蒿的不同生态型之间的生理生化特性上的差异的表现。作者从植物生态学的角度，对华中地区中亚热带常绿阔叶林北部亚地区山峡武陵山地所属的川东南、鄂西、湘西及黔东北各地进行了黄花蒿的生态环境调查及青蒿素含量测定。结果表明实验区域内黄花蒿的青蒿素含量普遍较高，平均在4．847‰～8．853‰之间，最高可达10．221‰，说明该区域的生态环境对黄花蒿中青蒿素成分的生物合成与转化有利。

In order to clarify the causes that Artemisia annua L.varies in the content of artemisinin with its production area,studies on the relationship between the content of artemisinin and ecological factors of A.annua were carried out.In this paper,we report results of the ecological environment investigation and quantitative analysis of artemisinin of A.annua in Southeast Sichuan,West Hubei,West Hunan and Northeast Guozhou districts.Our analytical results showed that A.annua growing in the above experimental area sproduced higher content of artemisinin,averaging at 4.847% ～8.853%.
