2003年—2016年安徽省谷物生产格局及变化特征

Evolution Pattern And Variation Characteristics of Grain Production in Anhui Province From 2003 to 2016

利用重心理论和地理信息技术,对安徽省2003年—2016年谷物产量和播种面积的生产格局及重心进行了研究,分析了谷物重心时空演变的驱动因素,结果表明:安徽省谷物种植地域差异明显,呈现"中北部多南部少"的格局,安徽省谷物种植北方以小麦和玉米为主,南方以稻谷为主,面积重心和产量重心分布具体表现为稻谷纬度最低;小麦居中;玉米纬度最高.稻谷、小麦二者产量重心较面积重心更偏西北,玉米产量及面积的重心分布较为接近.稻谷、玉米产量和面积重心向西北方向移动;小麦的产量和面积重心则向东南方向移动.

By using the gravity center theory and the GIS technology,the production pattern and the gravity center of grain production area from 2003 to 2016 in Anhui province are studied,and driving factors causing the spatiotemporal evolution of the gravity centerare are analyzed. Results show that the regional difference of grain planting in Anhui province is obvious,and the north and middle areas is more than the south. The northern part of Anhui province plants are mainly wheat and corn,while the Southern is mainly rice. Area center and yield center show the lowest latitude for rice,the middle for wheat and the highest latitude for maize. The yield centers of rice and wheat are more northwest than their area centers. The gravity center of the corn area and the yield gravity centeris relatively close. The gravity center of area and yield of rice and maize the rice production moves to the northwest. The gravity center of the wheat production locates at the southeast.
