摘要:

本研究采用县域数据,以广东省121个县(区)作为研究对象,分析2000—2019年粮食生产空间演变的动态路径以及重心变化以及2000—2019年广东粮食生产的重点区域和西南地区粮食生产的变化。结果表明:中部偏东的趋势较强,并逐渐以珠三角为中心向四周移动,总体呈现“东、西扩张、北波动、珠三角收缩”的态势。此外,粮食生产逐步向重点县转移,产粮10大县产量占广东省22%~25%,产粮前20位的产量占广东省的40%~43%,产粮前40位的产量占广东省的63%~68%,但近年来保持相对稳定。

Abstract:

In this study, county data from 2000 to 2019 were used to analyze the evolution process of the system and the change of grain production and center of gravity in microcosmic space with Guangdong Province as an example, so as to find out the change of grain production in key regions and southwest regions of Guangdong from 2000 to 2019. The results showed that the trend of the middle to the east was strong, and it gradually moved around with the Pearl River Delta as the center, showing a general trend of “east, west expansion, north fluctuation, and Pearl River Delta contraction”. In addition, grain production was gradually shifting to key counties. The output of the top ten grain producing counties accounted for 22%-25% of the provincial total output, the output of the top 20 grain producing counties accounted for 40%-43%, the output of the top 40 grain producing counties accounted for 63%-68%, and the regional pattern has remained relatively stable in recent years.

Key words: grain, spatial evolution, gravity center change, grouping, regional differentiation
