摘　　要："逆境"是道地中药材药理成分形成的主要原因之一,"逆境"提取是中药材估产、质量监测、培植区位选择以及道地性保护的前提。该研究结合3S(GIS,RS,GPS)技术,耦合"安苓"多源关键生态因子信息,首次利用生物间寄生关系,并对随季节显著变化的气温条件进行了季节细分,提取寄生种药材——"安苓"的"逆境"区。结果显示,"安苓"主要分布在大别山山区,适宜区面积达36.8 km^2,岳西、舒城、金寨、潜山4县占"安苓"总适宜区面积的93.55%,又尤以岳西、舒城、金寨3个县为主,占安徽茯苓适宜区总面积的80.82%,其中岳西县适宜区面积最大,占到了总适宜区的1/3以上。其与已有的调查估算结果具有高度的一致性,验证精度达91.67%,证实了利用3S技术结合药材关键非生物生态因子和寄生宿主信息提取寄生种中药材的可行性。＂Adversity＂ is one primary element that impacts the pharmacology components of authentic Chinese herbal medicine. Knowledge about ＂ adversity＂ is a precondition of yield estimation, quality monitoring, location selection and the geo-herbalism protec- tion. Used 3S（ GIS, RS and GPS） technology to combine multi-source key ecological factors of ＂Anling＂, and used parasitic relation- ships between organisms to extracting its suitable region for the first time. Results showed that the ＂Anling＂ were mainly distributed in Dabie coteau. Suitable area amount to 36. 8 km2 , Yuexi, Shucheng, Jinzhai and Qianshan which account for about 93.55% of whole congenial region. The first three accounts for about 80. 82%. It was Yuexi that account for 1/3 above especially. Field investigation verify accuracy of extraction about 91.67% , which has confirmed it is feasible that using the relationship between parasitic host and parasitic to extract native environment of parasitic traditional medicine based on 3S technology.
