摘　　要：通过对白术中白术内酯类成分含量与地形因子之间的相关性研究,对白术在全国主产区5省份的地形适宜性进行区划研究,为开展白术种植的合理区域选取提供科学的依据。在对全国5省份40个产地白术实地采样的基础上,应用统计分析方法,全面分析了不同地形因子条件下白术内酯类成分含量的变异,海拔、坡度、坡向对白术内酯类成分含量的影响。并应用空间技术,依据白术内酯类成分与地形因子之间的关系,进行了基于地形因子的白术生态适宜性区划。在我国南方丘陵地区和山区适宜白术生长,白术内酯类成分含量较高,北方平原地区区域内地形条件不适宜白术的生长,但可以将白术种植在区域内地形条件适宜白术的生长的丘陵和山区地带。最适宜白术内酯类成分积累的地形条件为海拔(200 m以上),坡度(3.00~4.99°)。Through study on the correlation between Atractylodis macrocephala lactones ingredient content and topographic factors, we researched regionalization from topography of five main producing provinces of the country, in order to provide a scientific basis for A. macrocephala reasonable cultivation. By sampling from 40 origins of five main producing provinces of the country, the variation of A. macrocephala lactones ingredient content in different conditions of topographic factors and the effect of altitude, slope and aspect was analyzed by SPSS. Then according to the relationship between A. macrocephala lactones ingredient content and topographic factors, the ecological suitability regionalization was conducted by using ArcGIS based on topographic factors. It is suitable for growth of A. macrocephala in the hilly and mountainous areas of southern whose A. macrocephala lactones ingredient content is in high levels. It is unsuitable for growth of A. m^rocephala in Northern plain areas, but we can cultivate A. macrocephala in the hilly and mountainous areas of Northern. The most suitable topographic condition for cultivation of A. macrocephala ： altitude 200 meters above, slope 3.00- 4.99 degrees.
