【摘要】：伴随"新型四化"同步快速推进,在短期内土地需求集中释放,造成城市周边优质耕地资源大量被建设用地所吞噬,而乡村耕地资源快速非农化与闲置低效利用并存的局面,对耕地资源保护与利用的硬要求有增无减,亟需推进耕地资源节约集约利用.本文首先从国家战略需求、区域发展需求和理论创新需求3个方面,阐明了耕地集约利用研究的时代要求,即它既是"保障粮食安全、破解三农问题、实现农业现代化转型"的国家战略需求,又是"构建新型农业经营体系,创新农业生产经营体制"的区域发展需求,还是"全方位、多尺度、多视角解析耕地集约利用特征"的理论创新需求.在此基础上,进一步对耕地集约利用的内涵及未来微观尺度研究的重点进行了思考与展望:耕地集约利用的内涵需顺应现代农业转型升级新要求而提炼升华,微观尺度耕地集约利用的研究需兼顾经营主体行为的异质性和动态性,并且驱动机理需系统分析地块-主体-区域环境.
[Abstract]:With the rapid development of the "new four modernizations", land demand is released in the short term, which results in a large number of high-quality cultivated land resources around the city being swallowed up by the construction land, while the rural cultivated land resources coexist rapidly and inefficiently. The hard demand for the protection and utilization of cultivated land resources is increasing, and it is urgent to promote the intensive utilization of cultivated land resources. In this paper, from three aspects of national strategic demand, regional development demand and theoretical innovation demand, this paper expounds the time requirement of intensive use of cultivated land, that is, it is "to ensure food security, solve the problem of agriculture, rural areas and farmers". The national strategic demand for realizing the transformation of agricultural modernization is also the regional development demand of "building a new agricultural management system and innovating the agricultural production and management system", or "all-around and multi-scale," The theoretical innovation demand of analyzing the characteristics of intensive utilization of cultivated land from multiple perspectives. On this basis, the intension of intensive use of cultivated land and the key points of future micro-scale research are further considered and prospected: the intension of intensive use of cultivated land should be refined and sublimated in accordance with the new requirements of modern agricultural transformation and upgrading. The study of intensive utilization of cultivated land on the micro scale should take into account the heterogeneity and dynamics of the behavior of the management agents, and the driving mechanism should be systematically analyzed to the landmass, the principal body and the regional environment.
