粮食安全视角下耕地“非粮化”现状及管控措施研究——以海西州乌兰县为例

Status and Control Measures of Farmland"Non-grain"from the Perspective of Food Security:a Case Study of Wulan County,Haixi Prefecture

耕地是粮食生产的根基,在粮食安全背景下,耕地“非粮化”问题受到广泛关注。为全面诠释乌兰县耕地“非粮化”问题,本文基于地方统计公报对乌兰县“非粮化”现状、驱动因素、管控措施进行了全面分析。研究得出,乌兰县“非粮化”比重偏高、主导类型明显、空间差异大,其驱动因素主要有粮经作物收益差值大、优质耕地少、当地特色产业突出等。针对其驱动因素提出了完善种粮惠民政策、推进耕地规划和中低产田改造项目、实行分区管控等遏制耕地“非粮化”的管控措施,以期为乌兰县耕地“非粮化”问题治理提供借鉴和参考。
