| 摘 要： | 粮食播种面积的变化及空间分布特征对农业的可持续发展以及粮食安全有着重要影响。本文采用GIS空间分析方法,以1949—2013年中国粮食播种面积变化为研究对象进行相关探讨。研究结果表明:中国粮食播种面积在近十年来重心北移十分明显;粮食作物中的豆类和薯类播种面积在1997—2013年呈现典型聚类分布特征;耕地减少对粮食播种面积的作用逐渐减弱,粮作比和复种指数成为影响粮食播种面积增长的主要因子;粮作比主要受农田基础设施建设、人口城镇化、农户种植习惯影响,与之呈现显著相关关系。

| Abstract: | The changes and spatial distribution of food sown area have an important effect on sustainable development of agriculture and food security in China.In this paper, GIS spatial analysis is applied to studying food sown area in China during 1949-2013 periods.The results show that spatial focus of Chinese food sown area has gradually moved towards north in recent 10 years.Clustering distribution has occurred in beans and tubers sown area from 1997-2013, and the main influencing factors causing changes of food sown area is no longer the variations of arable area but multiple cropping index and proportion of alimentary crop.The proportion of alimentary crop is significantly correlated with farmland infrastructure construction, planting habit and population urbanization rate. |
