摘 要 ：目的：筛选影响苍术Atractylodes lancea挥发油组分的气候主导因子,并实现苍术挥发油形成的气候适宜性区划,探索将GIS用于中药区划的技术和方法。方法：典型相关结合逐步回归得到气候因子与苍术挥发油的相关模型并确定影响苍术质量的气候主导因子；使用Surfer 7.0软件对30年间（1971～2000）影响苍术挥发油的气候主导因子的均值进行空间插值,使用ARCGIS软件的空间分析功能进行区划研究。结果：得到了气候因子与苍术挥发油中6个主要组分的相关模型,及苍术挥发油的气候适宜性区划图,发现10月份的气象条件对苍术挥发油组分的影响最大,温度及其与降雨的交互作用是影响苍术挥发油组分的气候主导因子。结论：苍术挥发油组分形成的气候适宜区与生长发育的气候适宜区不同。GIS技术用于中药区划研究有良好前景。

Abstract:To find the key factors that influence the content of the essential oil components of Atractylodes lancea and classify the habitat of A.lancea based the essential oil components,as well as explore a new method to conduct division of Chinese natural medicin through geographic information system (GIS) ultimately. Method： The key factors were obtained by canonical correlation and stepwise regressive analysis. Then the interpolation of climatic data for 30 years(1971-2000) was done by Sufer 7.0,and the habitat division was done by ARCGIS 9.0. Result： There were 6 correlation models between climate factors and 6 main essential oil componets were obtained, and a division map about essential oil components content of A. lancea base on clamate adaptability were drawn. It was found that the climate condition in Octobers played a key role on forming the essential oil components and the interaction of tempreture and precipitation was the most important factor on forming the essential oil components of A. lancea.Conclusion： The adaptive habitat for forming the essential oil components of A. lancea was different from growing A. lancea ones. And GIS can be used perspective for division of Chinese natural medicine.
