Abstract: East Asian synoptic charts, ground wind data in April, May of four counties of north Liaoning plain were selec ted to calculate the regional effects of protective forest system in reducing windspeed by geostrophic deviation method.The results show that the protection effects increased with increasing forestration area.Different protection effects of protective forest appeared at different daytime,with the greatest at 14:00, smallest at 2:00, the average windspeed reduced 13.3%.The characteristics of the geostrophic deviation method was also discussed.
