Various physical processes in association with magnetic reconnection occur over multiple scales from the microscopic to macroscopic scale lengths. This paper reviews multi-scale and cross-scale aspects of magnetic reconnection revealed in the near-Earth space beyond the general global-scale features and magnetospheric circulation organized by the Dungey Cycle. Significant and novel advancements recently reported, in particular, since the launch of the Magnetospheric Multi-scale mission (MMS), are highlighted being categorized into different locations with different magnetic topologies. These potentially paradigm-shifting findings include shock and foreshock transient driven reconnection, magnetosheath turbulent reconnection, flow shear driven reconnection, multiple X-line structures generated in the dayside/flankside/nightside magnetospheric current sheets, development and evolution of reconnection-driven structures such as flux transfer events, flux ropes, and dipolarization fronts, and their interactions with ambient plasmas. The paper emphasizes key aspects of kinetic processes leading to multi-scale structures and bringing large-scale impacts of magnetic reconnection as discovered in the geospace environment. These key features can be relevant and applicable to understanding other heliospheric and astrophysical systems.

与磁重联相关的各种物理过程发生在从微观到宏观尺度长度的多个尺度上。本文回顾了近地空间中揭示的磁重联的多尺度和跨尺度方面，超越了一般全球尺度特征和邓吉旋回组织的磁层环流。最近报告的重大和新颖的进展，特别是自磁层多尺度任务（MMS）启动以来，被强调分为具有不同磁拓扑的不同位置。这些潜在的范式转换发现包括冲击和前震瞬态驱动的重联、磁鞘湍流重联、流剪切驱动的重联、白天/侧翼/夜侧磁层电流片中产生的多个X线结构、重联驱动结构的发展和演化，例如通量传递事件、磁通绳和偶极前沿，以及它们与环境等离子体的相互作用。该论文强调了导致多尺度结构的动力学过程的关键方面，并带来了在地球空间环境中发现的磁重联的大规模影响。这些关键特征可能与理解其他日光层和天体物理系统相关并适用。
