基于共词网络分析的耕地“非粮化”阻断途径研究

Research on the Blocking Way of "Non Grain" Cultivated Land Based on Co-word Network Analysis

粮食安全能够得以保障的前提是耕地规模必须得到保证,然而,我国当前部分粮食主产区在不同程度上出现了耕地“非粮化”倾向,这大大动摇了粮食安全的根基。通过从期刊与报纸文献所关注的焦点问题入手,采用共词网络分析法进行分析。研究发现:可以从“土地流转”、“粮食种植”、“粮食安全战略”等方面入手解决耕地“非粮化”问题。

The premise of ensuring food security is that the scale of cultivated land must be guaranteed.However,at present,some major grain producing areas in China have the tendency of"non grain"cultivated land to varying degrees,which greatly shakes the foundation of food security.Starting from the focus of journals and newspapers,this paper uses co-word network analysis method to analyze the problem.It is found that the"non grain"problem of cultivated land can be solved from the aspects of land circulation,food planting,and food security strategy.
