中文摘要：

一个全球大气的一般发行量模型和异步地联合的全球气氛 -- 生物群系模型被用来模仿植被反馈在中间 -- 上新世约 3.3 ～ 3.0 百万年以前。为那个时期，模仿的植被在 62% 全球不冰冻的陆地表面不同于现在的条件。植被反馈几乎没在全球气候上有很少全面影响中间 -- 上新世。在地区性的规模，然而，交互植被在格林兰，北美洲的高纬度，东方欧亚大陆的中间高度的纬度，和西方的西藏上在年度温度导致了统计上重要的增加，并且在大多数在低纬度的陆地区域的减小，由于在表面反照率的导致植被的变化。

英文摘要：

A global atmospheric general circulation model and an asynchronously coupled global atmosphere-biome model are used to simulate vegetation feedback at the mid-Pliocene approximately 3.3 to 3.0 million years ago.For that period,the simulated vegetation differed from present conditions at 62％ of the global ice-free land surface.Vegetation feedback had little overall impact on the global climate of the mid-Pliocene.At the regional scale,however,the interactive vegetation led to statistically significant increases in annual temperature over Greenland,the high latitudes of North America,the mid-high latitudes of eastern Eurasia,and westem Tibet,and reductions in most of the land areas at low latitudes,owing to vegetation-induced changes in surface albedo.
