E st Asi n synoptic ch rts nd ground wind d t in April nd M y of four counties of nort h Li oning pl in were selec
ted to c lcul te the region l effects of protective forest system in reducing w indspeed by geostrophic devi t ion method.
The results show t h t the protection effects incre sed with incre sing forestr tion re . Different protection effects of
protective forest ppe red t different d ytime, w ith the gre test t 1400 nd sm llest t 200, nd the ver ge wind
speed reduced 13. 3% . The ch r cteristics of the geostrophic devi tion method w s lso discussed.
Key words Geostrophic devi tion, Region l protective effects of protective forest.
