摘要
我国农业可持续发展遭遇困境,未来粮食自给能力受到多种因素影响,国家粮食安全面临危机。影响我国未来粮食自给能力的主要因素为:第一,大量青壮年劳动力离开土地导致农业劳动力结构失衡,老龄化和女性化问题严重;第二,城市化、工业化等现代化的发展导致耕地资源面积减少及质量下降;第三,现代农业的发展对矿物能源产生过度依赖,动摇了粮食生产的基础;第四,全球气候复杂多变,中国农业表现出明显的脆弱性。
At present,the sustainable development of China＇s agricultural encounters difficulties,and the food self-sufficient ability in the future is affected by many factors,thereby the national food security is facing a serious crisis.According to the previous studies,there are four main factors will affect the China＇s food self-sufficient ability in the future： first,a large number of young labor force leave the land lead to imbalance of agricultural labor force,and the problem that agricultural labor force is aging and feminizing become serious;second,the development of modernization such as urbanization and industrialization lead to the decreasing area and quality of cultivated land resources;third,the development of modern agriculture over depends on mineral energy lead to a weak foundation for food production;fourth,with the complex and volatile global climate,China＇s agriculture showed significant vulnerability.
