Abstract: The GCM-SSiB global spectral model has been used to study the influence of afforestation in China land on regional climate.Two numerical experiments were set up.The results show that widen afforestation made annual mean surface air temperature higher,sea level pressure lower,low level zonal wind velocity weaker,the summer monsoon stronger,the winter monsoon weaker,updraft motion stronger in the summer and downdraft motion weaker in the winter,precipitation increased obviously,low level atmosphere specific humidity,surface evaporation flux,sensible heat flux and latent heat flux increased obviously.Regional climate will incline to be warm and humid after afforestation.Afforestation is in favor of ecology environment construction and controlling desertification.

Key words: afforestation, regional climate, numerical experiment
