【摘要】 植被对气候的反馈效应体现在植被影响了陆面-大气间水分、能量、动量的交换以及大气CO2浓度等各种生物物理和生物化学过程,从而对气候产生了直接或间接的影响。目前,植被对气候反馈作用的研究,主要基于观测分析、动力理论分析和数值模拟试验等三种研究途径,且已经获取了许多有关的研究结论,提高了我们对植被-气候反馈的认识。本文回顾了植被影响气候的研究历史,综述了国内外关键研究区域植被变化的观测事实和数值模拟实验研究的方法和研究结果,探讨了植被破坏和植被改善对区域气候的可能影响,并对植被变化气候效应的研究方向进行了讨论和展望。更多还原

【Abstract】 Vegetation impacts climate directly through biophysical processes that exchange moisture,energy,and momentum with the atmosphere and indirectly through biochemical processes that alter atmosphere CO2 concentration.Researches of the effect of vegetation change on climate have carried out through three methods:observation analysis,theoretical analysis and numerical simulation,and have received many important conclusions.Based on reviewing the researches of the feedbacks between vegetation and climate,this paper introduced observations and simulation results in sensitive regions,and discussed the influence of vegetation damage and improvement on climate.Further research topics were also discussed.更多还原
