- Abstract:
- The wind speed reduction capability of forest belt of Caragana korshinskili Kom in Yanchi,Ningxia Hui Autonomous Region in China is as follows.At the height of 0.5 m,the windbreak effect is row spacing 1.5 m (29.17%),3.0 m (28.67%).It is very similar in windbreak.But after 3H,row spacing 1.5 m better than row spacing 3.0 m about 2 times.At the point of 20H,the windbreak effect of row spacing 1.5 m is 16.36%.The windbreak effect of row spacing 3.0 m is 9.76%.Further analysis of row spacing 1.5 m and 3.0 m revealed that the wind reduction effect of 2-strip spread to 44.3H (H=1.0 m) and row spacing 3.0 m spread to 30.5H.This result implies that row spacing 1.5 m is most effective for windbreak.At the height of 1.0 m,the wind speed was relatively constant and the reduction rate of wind speed had a minimal variation,with the coefficient of determination of row spacing 1.5 m (8.95 m/s) and 3.0 m (6.70 m/s).The sandbreak effect of row spacing 1.5 m is the wilds (110.08 g)>3H(67.36 g)>7H(64.98 g)>5H(44.65 g)>1H(15.35 g).The sandbreak effect of row spacing 3.0 m is 3H (62.65 g)>the wilds(50.20 g)>1H(45.15 g)>5H(36.28 g)>7H(29.15 g).Especially,the rate of sandbreak of 1H (86.06%) of row spacing 1.5 m is most effective value in whole data.It is better than row spacing 3.0 m (10.06%) about 8.55 times.
