Effects of the Afforestation Models along the Beijing-Jiulong Railway on Aerodynamics in Daxing District of Beijing

  • Received Date: 2002-01-02
  • The effects of the afforestation models along the Beijing Jiulong railway on aerodynamics were studied with the case of eco economical shelterbelt. The trials were conducted in Daxing district of Beijing. The results showed that: the mean wind speed in the farmland protected by the eco economical shelterbelt (protected farmland) decreased by about 18.9% comparing with that in the open wide farmland(CK),and decreased by 30.0% as much at the spot which was 0.5H from the shelterbelt row(H: the tree height), but only 1.8% 7.1% in the range from 4H spot to the center of the protected farmland center; The efficient protective distance was 4H at least; The mean value of Richardson and turbulent coefficient in the protected farmland was 4.6% more and 14.7% less than that in CK respectively.

Abstract: The effects of the afforestation models along the Beijing Jiulong railway on aerodynamics were studied with the case of eco economical shelterbelt. The trials were conducted in Daxing district of Beijing. The results showed that: the mean wind speed in the farmland protected by the eco economical shelterbelt (protected farmland) decreased by about 18.9% comparing with that in the open wide farmland(CK),and decreased by 30.0% as much at the spot which was 0.5H from the shelterbelt row(H: the tree height), but only 1.8% 7.1% in the range from 4H spot to the center of the protected farmland center; The efficient protective distance was 4H at least; The mean value of Richardson and turbulent coefficient in the protected farmland was 4.6% more and 14.7% less than that in CK respectively.
