摘　　要：目的确定黄芪生长适宜性分布特征和区域,揭示其环境驱动因子影响规律,对陕北地区黄芪产业化种植培育和推广具有现实意义。方法本实验通过环境因子叠加得到陕北地区黄芪生长的适宜分布区,并采用地理探测器模型探测各环境因子对黄芪适宜生长的影响程度。结果神木县、吴起县、志丹县、定边县、府谷县的适宜区面积较大(包括适宜区和次适宜区),适合推广规模化人工种植和培育;各环境因子对研究区黄芪生长适宜性的影响差异显著。土壤类型和植被类型对黄芪生长适宜性的影响最大;多种环境因子对陕北地区黄芪生长适宜性的影响存在交互增强和非线性增强的关系。结论未来在陕北黄芪生长适宜性区县,应当加大黄芪种植、推广力度,同时重点关注关键环境影响因子如土壤类型和植被类型的变化特征,以及它们之间的交互作用,以期逐步实现陕北地区黄芪标准化、规模化培育。OBJECTIVE To determine the distribution characteristics and suitable growth regions of Astragali Radix and reveal the influencing rules of the environmental driving factors,which are of practical significance to the cultivation and promotion of Astragali Radix in the northern Shaanxi region.METHODS The suitable distribution area of Astragali Radix in northern Shaanxi was obtained by superposition of environmental factors.RESULTS The suitable areas in Shenmu,Wuqi,Zhidan,Dingbian and Fugu county were found(including suitable area and sub-suitable area),which was suitable for large-scale artificial cultivation.Significant difference presented in the effects of environmental factors on the growth suitability of Astragali Radix,and environmental factors were mainly represented by the soil type and vegetation type.A significant interactive relationship of mutual enhancement and nonlinear enhancement was found in the influence of environmental factors on the growth suitability of Astragali Radix.CONCLUSION In the future,effort should focus on the promotion of the cultivation of Astragali Radix in the suitable growth region in northern Shaanxi and the change characteristics of the key environmental impact factors.ie,soil type,vegetation type,and their interactions,so as to gradually achieve the standardization and large-scale cultivation of Astragali Radix in northern Shaanxi area.
