甘肃省作为我国马铃薯主要产区，探索其种植科学性及适宜性，对优化我国马铃薯产业布局具有重要意义。通过布设采样点对甘肃省马铃薯产区水、热、光等气象资源、立地条件以及土壤理化性状数据进行调查，利用SPSS26.0、GS+软件对调查数据进行分析，用Arcgis10.8普通克里格插值法对相关数据进行插值处理，用拉斐尔法构建评价指标体系对马铃薯种植区域进行适宜性评价。结果显示，甘肃省马铃薯种植高度适宜区、适宜区、勉强适宜区和不适宜区的面积分别为98.86万hm2、213.36 万hm2、120.00万hm2、88.75万hm2，分别占全省耕地总面积的18.98%、40.95%、23.03%和17.04%。影响甘肃省马铃薯适宜性分布的主要因素为海拔、年降水量和年平均气温。

Gansu Province is China's primary potato producing region. Exploring the suitability of potato cultivation is of great significance for optimizing the layout of China's potato industry. Thus, this study investigated the potato farming region in Gansu Province, examined factors such as water, heat, light, and other meteorological resources, as well as site conditions and physical and chemical soil characteristics. Data analysis was performed using SPSS 26.0 and GS+. And the Arcgis 10.8 ordinary kriging interpolation was used for interpolation, the Raphael's method was applied to construct an evaluation indicator system for suitability evaluation of potato production areas. Results showed that the highly suitable, suitable, barely suitable and unsuitable areas for potato production in Gansu were 988 600 ha, 2.1336 million ha, 1.20 million ha and 887 500 ha, respectively, corresponding to 18.98%, 40.95%, 23.03% and 17.04%of the Gansu Province's total cultivated area, respectively. Several key factors influenced the distribution of potato suitability in Gansu Province, namely altitude, annual precipitation and annual average temperature.
