摘要
基于2012—2021年广西县域的耕地面积、粮食产量、人口以及粮食播种面积等数据,运用最小人均耕地面积和耕地压力指数模型,在人口-耕地-粮食系统视角下,对广西县域近十年人口-耕地-粮食变化特征及耕地压力指数进行分析,研究结果表明:近十年广西县域耕地面积逐年减少、人均粮食产量不断提高,但总体低于全国平均水平,部分县域耕地压力指数异常。建议通过强化人才支撑、严格保护耕地和强化粮食物流、存储系统等措施,促进广西县域人口-耕地-粮食系统协调发展。
Based on the data of cultivated land area,grain yield,population and grain sown area of Guangxi counties from 2012 to 2021,the minimum per capita cultivated land area and cultivated land pressure index model were used to analyze the characteristics of population-cultivated land-grain change and cultivated land pressure index of Guangxi counties in the past ten years from the perspective of population-cultivated land-food system.The research results showed as follows:In recent ten years,the cultivated land area of Guangxi counties has been decreasing year by year,and the per capita grain production has been increasing,but it is lower than the national average,and the cultivated land pressure index of some counties is abnormal.It is suggested that the coordinated development of population,cultivated land and food system in Guangxi counties should be promoted by strengthening the support of talents,strictly protecting cultivated land and strengthening the grain logistics and storage system.
