地表反照率表征地球表面对太阳辐射的反射能力,决定着地表与大气之间辐射能量的分配过程,是影响地球气候系统的关键变量。在全球变化日益突出的今天,地表反照率与全球变化的相互影响机制已经成为地球科学研究领域的热点问题之一。地表反照率的细微变化,会影响到地气系统的能量收支平衡,进而引起区域以至全球气候变化。详细介绍地表反照率影响因素、研究方法等方面的最新研究进展,并从全球变化的角度阐述地表反照率的研究动态及其研究方向。
Surface Albedo, which characterizes the ability of the Earth’s surface to reflect solar radiation, determines the distribution of radiant energy between the Earth’s surface and the atmosphere and is a key variable affecting the Earth’s climate system. At a time when global changes are increasingly prominent, the interaction between surface albedo and global change has become one of the hot issues in the field of geosciences. Subtle changes in the surface albedo will affect the energy balance of the geogas system, which in turn will cause regional and global climate change. This paper introduces in detail the latest research progress on the influencing factors and research methods of surface albedo, and then introduces the research trends and research directions of surface albedo from the perspective of global change.
