中国作物生产及非粮化时空演变研究
Journal: Agricultural Science DOI: 10.12238/as.v8i2.2756
Abstract
21世纪以来,农业区尤其是粮食主产区的作物生产格局经历了显著变化。本研究基于2000年与2015年间中国14种主要作物的种植面积、单产及产量数据,探讨了作物生产的时空演变及非粮化趋势,重点分析了农业区及其粮食主产区的变化特征。研究结果表明：粮食主产区的作物总种植面积和产量增长较快,且占全国的比重也不断提升。此外,谷物类作物的生产逐渐向北方农业区集中,而南方及西部地区在油料、甜料和纤维作物的产量有所增长。各农业主产区内的非粮化现象却不断减轻。本研究有助于深入理解作物生产格局的调整趋势,并为未来粮食安全保障政策的制定提供科学依据。
