- Abstract:
- We measured different spacing shelter forest wind velocity flow field and inter-type vegetation of Caragana korshinskii in Siziwang Banner, and studied the wind reducing effect and the form of inter-type vegetation. The results show that: (1) Caragana korshinskii shelter forest has the reduction impact on wind speed, as well appeared the wind shadow area and accelerating area all in different contrast of wind speeds; (2) the wind protection effects decreased in the order: 4 m > 6 m > 8 m in the height of 0 to 2 meters from the ground, and 8 meters wide belt-type not only has an effect on low wind speed (6~8 m/s), but also can control the high wind speed (10 m/s) by four belt blocks; (3) Thymus mongolicus, Setaria viridis and Artemisia herb community appear in 8 meters wide forest, which is close to the zonality herb community (Leymus chinensis and Artemisia frigida) and shows that its recovery effect is obvious. This study ensures that the bandwidth and the amount of forest can provide survive for the future construction of wind resistance forest belt mixed multiple tree species and provide important scientific basis for the confirmation of the configuration mode.
