耕地资源系统认知的演进与展望

耕地是人类改造和利用地表而形成的最古老和最广泛的人地系统,耕地质量是耕地系统诸要素耦合状态的表达,耕地资源是在一定时间、技术和经济条件下耕地开发利用价值的体现。本文厘清了耕地系统、耕地质量、耕地资源认知内涵与演进过程,解析了耕地资源的“自然-人文”构成要素与耦合关系、“水平-垂直”结构特征与形成机理、“生产-生态-生活”功能协同与转换关系、“物质-能量-信息”交换过程与响应机制,以及“经济-生态-社会”服务价值与演变规律,构建了“二维要素-三重功能-多元价值”的耕地资源认知系统,提出了系统认知耕地资源的新思路,解构了耕地资源内部机制与外部价值,以期为耕地保护与质量提升及自然资源资产“两统一”管理提供理论依据,推动高质量跨越式发展的耕地保护与资源利用新格局构建。

Evolution and prospect of systematic cognition on the cultivated land resources

Cultivated land is the oldest and most extensive human-land system formed by human civilization through the transformation of the earth''s surface for thousands of years. The ability of cultivated land system to maintain stable production and healthy environment is reflected in the quality characteristics of cultivated land, under certain technical and economic conditions within a certain period of time, and the development and utilization value is expressed as the resource attribute of cultivated land. This paper clarifies the cultivated land system, the quality of cultivated land and cultivated land resources, on the basis of cognitive connotation and evolution process. The "nature-humanity" constituent elements and their coupling relationship of cultivated land resources are analyzed, characteristics and formation mechanism of "horizontal-vertical" structure, "production-ecology-living" function synergy and transformation relationship. The exchange process and response mechanism of "matter-energy-information", and the service value and evolution law of "economy-ecologysociety", the cognitive system of cultivated land resources is constructed, which is "two-dimensional factor-triple function-multiple value". A new way of systematically recognizing cultivated land resources is proposed, deconstructing the internal mechanism and external value of cultivated land resources, service farmland protection and quality improvement and natural resource assets "two unified" management, to support the construction of a new pattern of resource utilization and cultivated land protection under high-quality crossdomain development.
