摘要: 分不同地区和作物，对黄土高原小杂粮生产情况进行了系统研究，表明小杂粮在黄土高原旱作农区粮食生产中居重要地位。山西省小杂粮播种面积最大，甘肃省次之，宁夏回族自治区播种面积虽不及陕西省，但所占粮食播种面积的比重却较高。在不同小杂粮作物中，以马铃薯分布面积最大，谷子次之，其后依次是荞麦、绿豆，其他作物则分布相对较少。同时对小杂粮分布最为集中的黄土高原水土流失区主要小杂粮作物区域分布进行了研究，将该区分为3个区，10个亚区，评述了各区主要小杂粮生产和分布特点，为合理开发小杂粮资源提供决策依据。

Abstract: The production situation of minor crops in the Loess Plateau of China was systematically analyzed based on crop species and regions of the study area. It is shown that minor crops play a very important role in grain production on the dry-lands of the Loess Plateau. Cultivated area of minor crop plants is largest in Shanxi Province，closely followed by Gansu. Ningxia Hui Autonomous Region has a lower minor crop planting area than Shaanxi，but its ratio to crop planting area is higher in Ningxia than Shaanxi. Among the different crops，cultivated area of potato is the biggest，then millet，buckwheat and mung bean in that order. Also the distribution of minor crops in the dry-lands of the Loess Plateau is divided into 3 major- and 10 sub-areas，and the main minor crop production and distribution characteristics of the different divisions were analyzed to provide policy and scientific bases for rational utilization of minor crop resources.
