摘　　要：目的:了解定西市栽培当归生态适宜性,筛选影响其分布的主要生态因子。方法:通过走访和实地调查,从定西市当归栽培县区获取857个采样点的经度、纬度、海拔等地理信息,结合全国生态因子数据,利用Maxent模型和ArcGIS软件的空间分析功能进行分析。结果:定西市栽培当归适宜分布区主要集中在定西市南部岷县、漳县,渭源县、临洮县、陇西县也有分布,但适宜区域较小。影响定西市当归适宜性分布的主要生态因子为海拔高度、降水量、温度。结论:本研究对定西市栽培当归生态适宜区进行了等级划分,生成了当归生态适宜性区划图,可为定西市当归合理引种栽培提供理论依据。Objective: To understand the ecological suitability of cultivated Angelicae Sinensis Radix in Dingxi City and select the main ecological factors affecting its distribution. Methods: Through visiting and field investigation, the longitude, latitude and altitude of 857 sampling points in Dingxi City were obtained by GPS. Maxent model and ArcGIS software were used to analyze. Results: Suitable distribution areas of cultivated Angelicae Sinensis Radix were mainly concentrated in Min County and Zhang County in the south of Dingxi City. Weiyuan county, Lintao County, Longxi County also had small distribution areas. The main ecological factors affecting the suitability distribution of Angelicae Sinensis Radix were altitude, precipitation and temperature. Conclusion: In this study, the ecological suitability zones of Angelicae Sinensis Radix in Dingxi City are classified, and the map of ecological suitability zones of Angelicae Sinensis Radix is generated, which could provide scientific basis for rational planning of Angelicae Sinensis Radix cultivation areas in Dingxi City.
