国内外耕地撂荒研究进展

Research Progress of Farmland Abandonment at Home and Abroad

研究目的:总结国内外耕地撂荒相关研究进展,提出耕地撂荒进一步研究的方向。研究方法:文献资料法。研究结果:国内学者日益关注中国耕地撂荒问题及其表现和影响,较多从撂荒的影响因素和对策建议进行研究;国外学者同样侧重于耕地撂荒影响因素以及对策建议的研究,较少侧重关于撂荒地的识别技术。研究结论:耕地撂荒研究对保障我国粮食安全和土地集约节约利用具有重要意义,未来应建立统一的耕地撂荒的影响因素指标体系,将大尺度遥感判读与农户问卷调查相结合,加强预测耕地撂荒的发展趋势,为开展中国耕地撂荒问题研究提供理论和方法借鉴。

Research purpose: Summarize the research progress on farmland abandonment at home and abroad, and propose further research directions for farmland abandonment. Research method: Literature review method. Research results: Domestic scholars have increasingly paid attention to the issue of abandoned farmland in China, its manifestations and impacts, and have conducted research on the influencing factors and countermeasures of abandoned farmland;foreign scholars also focus on the research on the influencing factors and countermeasures of abandoned farmland, with less emphasis on the identification technology of abandoned land. Research conclusion: The study of arable land abandonment is of great significance for ensuring food security and intensive and economical land use in China. In the future, a unified indicator system for the influencing factors of arable land abandonment should be established, combining large-scale remote sensing interpretation with household questionnaire surveys to strengthen the prediction of the development trend of arable land abandonment and provide theoretical and methodological references for conducting research on the issue of arable land abandonment in China.
