摘要: 利用东亚地面天气图和地面风的资料,用地转偏差方法,计算了辽河平原北部4县农田防护林体系的区域性防风效应,结果表明,随着防护林面积的增大,其防风效应增大;每天不同时间防风效应不同,14:00最大,2:00最小,平均为13.3%.还对地转偏差方法的特点进行了讨论.

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.
