摘　　要：农业经营格局的时空分析有助于把握现代农业发展的空间差异机制。采用1990—2012年广东省农业产值及其经营结构数据,引入重心模型,对广东省农业经济重心在时空上的动态演变轨迹进行实证研究,并分析主要农产品的时空分布特征,进而反映农业经营格局与区域差异。结果表明:广东省农业经济重心呈现向西南移动的趋势,形成"西高东低、南高北低"的空间格局;主要农产品形成规模化的集聚生产格局,粤西地区成为区域农业专业化生产优势区。农业经营格局演变受自然、社会、经济、技术等因素驱动。自然资源条件是农业经营格局形成的客观基础,社会、经济和技术等因素是农业经营格局改变的重要驱动力量,且其作用逐步增强。The temporal-spatial analysis on the agricultural management pattern can help us to understand the mechanism of the changes about modern agriculture. By using gross output value of farming, forestry, animal husbandry and fishery, data of Guangdong in 1990 to 2012, the gravity center model was established, from which we could analyze temporal-spatial evolution of the gravity center of agricultural economic and the distribution of the main agricultural products. The results showed that from 1990 to 2012, the center-of-gravity of agricultural management pattern moved towards southwest. The movement of farming, animal husbandry and fishery was more obvious. Spatial concentration of main agricultural products increased. At the same time, west wing of Guangdong province progressively became predominance area of regional specialized production. It＇s concluded that natural resource endowments, social and economic growth, technological innovation were the main driving forces, and social and economic growth, technological innovation played a more important role.
