Large knowledge gaps currently exist that limit our ability to understand and characterise dynamics and patterns of land-use intensity: in particular, a comprehensive conceptual framework and a system of measurement are lacking. This situation hampers the development of a sound understanding of the mechanisms, determinants, and constraints underlying changes in land-use intensity. On the basis of a review of approaches for studying land-use intensity, we propose a conceptual framework to quantify and analyse land-use intensity. This framework integrates three dimensions: (a) input intensity, (b) output intensity, and (c) the associated system-level impacts of land-based production (e.g. changes in carbon storage or biodiversity). The systematic development of indicators across these dimensions would provide opportunities for the systematic analyses of the trade-offs, synergies and opportunity costs of land-use intensification strategies.

分析和测量土地利用强度的概念框架。

目前存在的巨大知识差距限制了我们理解和描述土地利用强度动态和模式的能力：特别是缺乏全面的概念框架和测量系统。这种情况阻碍了对土地利用强度变化的机制、决定因素和制约因素的深入理解。在回顾研究土地利用强度的方法的基础上，我们提出了一个量化和分析土地利用强度的概念框架。该框架整合了三个维度：(a) 投入强度，(b) 产出强度，以及 (c) 陆地生产的相关系统层面影响（例如碳储存或生物多样性的变化）。
