耕地多功能内涵及其对耕地保护的启示

近年来,耕地多功能管理引起了国内外的广泛关注。针对耕地需求无序竞争、耕地边际化与耕地生态系统退化三大现实问题,建立了以土地单功能利用为症结的综合分析框架,认为中国耕地保护须向耕地多功能管理转型。然而,目前尚缺乏耕地多功能的内涵解释框架。本文通过梳理耕地多功能的相关研究,从实证与规范、供给与需求及其相互关系角度,建立了耕地多功能内涵的综合解释框架。最后,本文提出耕地保护转型可同时注重构建以主体功能差异化为前提的耕地多功能空间融合模式、拓展耕地价值的提升途径并建立耕地多功能统筹利用保障机制。

Connotation of Multifunctional Cultivated Land and Its Implications for Cultivated Land Protection

Recently,multifunctional cultivated land(MCL) management has been a hot topic in the world.To get a deep understanding of the challenges such as the disorderly competition of cultivated land demand,marginalization of cultivated land and degradation of cultivated ecosystem,a comprehensive analytical framework was established based on the crux of mono-functional land use.From this point of view,it is vital to promote the transition of cultivated land protection towards the MCL management.However,there is no explanation framework of the connotation of the MCL.From the standpoints of positive and normative meanings,supply and demand meanings and the relationships among them,this paper established a comprehensive explanation framework through literature review.Finally,suggestions on promoting the transition such as establishing the spatial integration mode of the MCL based on main function differentiations,expanding the channels of cultivated land value enhancement and establishing the safeguard mechanism of integrated use of the MCL were proposed.
