为了在伊朗萨鲁克流域确定黄芪适生区，首先在实地考察和专家经验的基础上，确定了方向、坡度、海拔、温度、降雨量和土壤质地等6个主要有效指标。然后利用层次分析法(AHP)对专家选择11软件中的问卷形式进行加权，计算出各指标的相对重要性及其所属类别。最后，将得到的地图在ArcGIS软件中进行叠加，确定黄芪的适宜区域。结果表明，北方地区具有较高的优先地位。其中相对重要性最大(0.5101)的海拔高度在1800m以上，海拔在1800m以上的地区适合黄芪生长。海拔、降雨量和温度三个主要指标的权重分别为0.3043、0.2201和0.1550，它们的相对重要性最大，就位置而言，排名第一到第三。总体而言，在萨鲁克流域总面积中，有553公顷被确定为黄芪树种适宜区。研究表明，利用技术、地理信息系统和层次分析法，可以用最少的费用和时间确定不同土地上药用植物的最佳选址。
In order to locate Astragalus appropriate areas in Salook watershed, Iran, at the first, six main effective criteria including direction, slope, altitude, temperature, rainfall and soil texture were determined based on fields study and expert experiences. Then using the analytic hierarchy process (AHP) method were weighted based on questionnaire form in the expert choice 11 software, and relative importance of each criteria and their classes were calculated. Finally, obtained maps were overlaid in ArcGIS software to determine Astragalus appropriate areas. The results showed that Northern area have higher priority than other. With the most relative importance (0.5101), the heights above 1800 m the heights above 1800 m suitable sites for Astragalus spp. The three main criteria including altitude, rainfall and temperature with the weight of 0.3043, 0.2201 and 0.1550 have the most relative importance respectively and in terms of the location are in the first to third priority. In general, from the total area of Salook watershed, 553 hectares was identified as Astragalus species suitable site. This research showed that using technology and GIS and AHP and with the least cost and time, the optimal location of medicinal plants can be determined in different lands.
