地表反照率在地表能量收支中起着控制作用，反照率引起的辐射强迫对气候和环境变化(如全球变暖、冰雪融化、土壤和植被退化以及城市热岛)具有重大影响。现有的几篇综述论文总结了地表反照率的算法和产品以及某些地表的气候反馈，但对各种土地类型的总体了解仍然不足，特别是近年来关于减缓全球变暖的反照率管理方法的研究越来越多。本文对地表反照率的变化模式、随后的气候影响和反照率管理策略进行了全面的文献综述。结果表明，建议使用更具体的术语“地表反照率”而不是“反照率”，以避免与类似的术语(例如行星反照率)混淆，并且地表反照率的时空变化可表明能量收支、土地覆盖甚至特定地表结构的微妙变化。此外，地表反照率变化和气候反馈之间的密切关系强调了反照率在气候模拟和预测中的重要作用，许多反照率管理策略(例如，使用逆向反射材料(RRMS))已被证明通过抵消二氧化碳排放而有效地缓解气候变化。在今后的工作中，需要系统地评估多种时空分辨率的地表反照率的气候影响和管理战略，以促进其在气候缓解中的应用，其中应采用同时考虑气候益处和副作用(如热舒适性)的生命周期评估(LCA)方法。
Surface albedo plays a controlling role in the surface energy budget, and albedo-induced radiative forcing has a significant impact on climate and environmental change (e.g., global warming, snow and ice melt, soil and vegetation degradation, and urban heat islands (UHIs)). Several existing review papers have summarized the algorithms and products of surface albedo as well as climate feedback at certain surfaces, while an overall understanding of various land types remains insufficient, especially with increasing studies on albedo management methods regarding mitigating global warming in recent years. In this paper, we present a comprehensive literature review on the variance pattern of surface albedo, the subsequent climate impact, and albedo management strategies. The results show that using the more specific term “surface albedo” is recommended instead of “albedo” to avoid confusion with similar terms (e.g., planetary albedo), and spatiotemporal changes in surface albedo can indicate subtle changes in the energy budget, land cover, and even the specific surface structure. In addition, the close relationships between surface albedo change and climate feedback emphasize the important role of albedo in climate simulation and forecasting, and many albedo management strategies (e.g., the use of retroreflective materials (RRMs)) have been demonstrated to be effective for climate mitigation by offsetting CO2 emissions. In future work, climate effects and management strategies regarding surface albedo at a multitude of spatiotemporal resolutions need to be systematically evaluated to promote its application in climate mitigation, where a life cycle assessment (LCA) method considering both climate benefits and side effects (e.g., thermal comfort) should be followed.
