摘　　要：通过走访和实地调查,收集当归在全国的栽培信息。以当归药材主产区43个采样点为分析基点,分析当归各类功效性成分,综合气候、地形等相关生态因子,利用GIS技术和最大信息熵模型分析当归适宜性分布。应用R语言构建当归有效成分与环境因子之间的关系模型,采用ArcGIS软件空间计算方法进行当归品质区划。研究结果显示影响当归适宜性分布的主要生态因子为海拔、土壤亚类、5月份降水量和最暖月最高温等4个生态因子,这与当归喜冷凉湿润气候,适宜于分布在土层深厚区域的生活习性相一致。此外,以当归功效性成分为指标的生态适宜性区划结果还提供了传统分布区以外的新适宜分布区,为开展当归合理引种栽培提供了科学依据。The distribution information of Chinese angelica was collected by interview investigation and field survey, and 43 related environmental factors were collected, some kinds of functional chemical constituents of Angelica sinensis were analyzed. Integrated cli- mate, topography and other related ecological factors, the habitat suitability study was conducted based on Arc geographic information system（ArcGIS） ,and maximum entropy model. Application of R language to establish the relationship between the effective component of Chinese angelica and enviromental factors model, using ArcGIS software space to carry out space calculation method for the quality regionalization of Chinese angelica. The results showed that 4 major ecological factors had obvious influence on ecology suitability distri- butions of Chinese angelica, including altitude, soil sub categm~~, May precipitation and the warmest month of the highest temperature, et al. It is suitable for the living habits of the Chinese angelica, cold and humid climate, which is suitable for the deep area of the soil. In addition, the ecological suitability regionalization based on the effect of Chinese angelica also provides a new suitable distribution ar- ea other than the traditional distribution area, which provides a scientific basis tor the reasonable introduction of Chinese angelica.
