中文摘要：

人类活动引起的土地利用／覆盖变化（Land Use and Land Cover Change，LUCC）是重要的外强迫之一，但是LUCC对全球及区域气候影响的研究仍然薄弱，至今无法对LUCC的气候效应问题做出系统的评估。研究针对人类活动比较剧烈的中国区域问题，首先回顾了近几十年来中国LUCC的特征，接着从观测和数值模拟2个方面系统地讨论了过去LUCC的研究成果，主要针对LUCC通过生物地球物理过程影响区域气候的工作，总结和归纳了LUCC对中国区域气候的影响问题，进而探讨了LUCC在未来气候变化中可能扮演的角色、亟待解决的问题，以及国内外在这方面的研究动态和未来发展方向。

英文摘要：

Land Use and Land Cover Change （LUCC） due to human activities is one of important anthropo- genie forcings. However, the effects of LUCC on global and regional climate have not been addressed in depth yet. In particular, a systematic evaluation of the climatic effects associated with LUCC is lacking. In this paper, we reviewed the observational and simulation findings of LUCC-related issues, focusing on the characteristic of LUCC in China in recent decades and the impacts of biogeophysical processes on regional climate. The roles of LUCC in fu- ture projections and the issues which should be further studied were also discussed. In addition, the latest research tendency and future focuses at home and abroad were also described.
