为了解决当归连作障碍，促进当归实现种植科学化、精细化。通过布设采样点对岷县当归产区水、热、光等气象资源和土壤资源进行调查，利用SPSS 26.0、GS+软件调查采样数据进行统计分析，用普通克里格插值法进行插值处理，构建岷县当归评价指标体系，通过利用特尔斐法建立岷县当归层次分析模型进行适宜性评价。结果表明，岷县当归种植高度适宜区、适宜区和勉强适宜区的面积分别为664.27、175.53、29.87 km2，分别占全县耕地总面积的76.4%、20.2%、3.4%；影响岷县当归适宜性分布的主要因素为海拔、降水量、年平均温度和零度积温。

To address the issues in continuous cropping of Angelica sinensis, to promote the scientific and precision cultivation of Angelica sinensis, based on the climate and environment survey in Min County by collecting meteorological resource data such as water, heat, light and soil resource, the evaluation index system of characteristic superior agricultural products of Angelica sinensis in Min County was constructed by using SPSS 26.0 and GS and survey data, the index system was used to evaluate the suitability of Angelica sinensis origin in the whole county. The results show that the highly, moderately, and barely suitable areas for Angelica sinensis planting were 664.27 km2, 175.53 km2, and 29.87 km2, respectively, which occupied 76.4%, 20.2%, and 3.4% of farmland in the county, respectively. The main factors affecting the suitability distribution of Angelicae sinensis were altitude, precipitation, mean annual temperature and accumulated temperature ≥0℃.
