摘　　要：吃饱和吃好成为新形势下粮食安全的核心问题。通过明确冷凉地区概念及范围界定,采用K-means聚类对中国中海拔冷凉区内43500个10 km精度的格网要素进行以农业生产为主导功能的空间识别和类型分区。结果显示:(1)中海拔冷凉区面积约263万km^(2),约占陆地国土总面积的28.47%,主要集中分布于东北、西北和西南9省域的山地高原地形区;(2)中海拔冷凉区可划分为以林为主山地湿冷区、以林为主高山温凉区、以农为主耕地旱凉区、以牧为主高原旱冷区、以牧为主高山高寒区五种农业发展类型;(3)农林牧优势发展区域栅格面积占比分别为9.97%、34.21%和55.82%,区县占比分别为27.34%、35.90%和36.76%。研究结果为探索特色农业布局与山区独特冷凉气候资源相结合提供科学依据,对新时期保障粮食安全和实现乡村振兴战略具有重要实践意义。Eating well has become the core issue of food security in the new situation.By clarifying the concept and scope definition of cold and cool areas,K-means clustering was used to spatially identify and type 43500 grid elements with 10 km accuracy in China's mid-altitude cold and cool regions with agricultural production as the dominant function.The results show that:(1)The mid-altitude cold and cool regions cover an area of about 2.63 million km2,accounting for roughly 28.47%of the total land area,and are mainly concentrated in the mountainous and plateau topography of nine provincial-level regions in the northeast,northwest and southwest parts of China.(2)The mid-altitude cold and cool regions can be divided into five types of agricultural development:forest-dominated mountain wet and cold regions,forest-dominated alpine warm and cold regions,agriculture-dominated cropland arid and cold regions,pasture-dominated plateau arid and cold regions,and pasture-dominated alpine high and cold regions.(3)The raster area of farming,forestry and animal husbandry favourable development area is 9.97%,55.82%and 34.21%,and the district and county share is 27.34%,35.90%and 36.76%,respectively.This paper provides a scientific basis for exploring the combination of characteristic agricultural layout and unique cold climate resources in mountainous areas,which is of great practical significance for ensuring food security and realising the rural revitalisation strategy in the new period.
