Land change science has emerged as a fundamental component of global environmental change and sustainability research. This interdisciplinary field seeks to understand the dynamics of land cover and land use as a coupled human-environment system to address theory, concepts, models, and applications relevant to environmental and societal problems, including the intersection of the two. The major components and advances in land change are addressed: observation and monitoring; understanding the coupled system-causes, impacts, and consequences; modeling; and synthesis issues. The six articles of the special feature are introduced and situated within these components of study.
土地变化科学已成为全球环境变化与可持续性研究的一个基本组成部分。这个跨学科领域旨在将土地覆盖和土地利用的动态变化理解为一个耦合的人类-环境系统，以解决与环境和社会问题相关的理论、概念、模型及应用，包括二者的交叉问题。文中探讨了土地变化的主要组成部分和进展：观测与监测；理解耦合系统——成因、影响及后果；建模；以及综合问题。还介绍了该专题的六篇文章，并将其置于这些研究组成部分的范畴内。
