【摘要】 “三生”空间识别与管控体系是新时代国土空间规划与治理的核心要义，也是实现区域可持续发展的关键举措。当前相关研究面临“三生”空间的属性认知与其理论建构存在偏差“、三生”空间识别抽象化与落地实施精细化之间的传导脱节“、三生”空间刚性管控与土地利用功能的动态性不相适应等实践困境。土地系统科学可为开展“三生”空间的精细识别与动态管控研究提供有益视角。据此，本文系统梳理了土地系统科学的思想缘起，阐释了土地系统的内涵差异与运行结构，厘清了土地系统状态的理论描述及量化表征；以本体一致性、目标契合性、过程关联性和效应互馈性为切入点，归纳凝练出土地系统科学和“三生”空间识别与管控的多维立体衔接关系，并尝试构建了二者之间以土地系统状态为核心的逻辑机制；进而在理论基石、技术通道和实践愿景方面依序提出了土地系统科学支撑“三生”空间识别及管控的关键破解路径。未来应依据现有理论体系开展典型案例实践，以拓展土地系统科学的应用边界，为破解全域范畴的“三生”共赢难题提供技术方法。更多还原

【Abstract】 The identification and management of production-living-ecological space(PLES) is the core essence of territorial spatial planning and governance in the new era, and a key initiative to achieve regional sustainable development. Currently, research in this field faces practical dilemmas such as the discrepancy between the attribute cognition of PLES and its theoretical construction,the disconnection between the abstract identification of PLES and the refinement of its implementation, and the mismatch between the rigid management of PLES and the dynamic land functions.Land system science can provide a beneficial perspective for conducting research on the detailed identification and dynamic management of PLES. Accordingly, this paper systematically reviews the ideological origin of land system science, elaborates the internal differences and operational structure of the land system, and clarifies the theoretical description and quantitative expression of the land system states. Based on ontological consistency, goal alignment, process relevance, and effect reciprocity, this paper summarizes, this paper summarizes the multi-dimensional interconnected relationship between land system science and the identification and management of PLES, attempts to construct a logical mechanism centered on the land system states between them, sequentially proposes the key solution paths for land system science to support the identification and management of PLES in terms of theoretical foundation, technical channels and practical vision. In the future, it is necessary to conduct typical case practices based on the existing theoretical system to expand the application boundaries of land system science and provide technical methods to solve the problem of PLES coordination in the whole domain.更多还原
