Simulating Efficiency of Resistance to Wind Erosion in Area of Complex Erosion by Wind and Water

Abstract:

Used the method of transplanting in studying area, simulated different arrangement of plant spacing and observed the wind speed by using HTSW-18 multiple-sensor automatic anemoscope. The results showed that two kinds of plants of different plant spacing can effectively reduce wind speed, the ration of reducing wind velocity of shelterbelts were biggest at the observation point of 1H behind the shelterbelt. The ration of reducing wind velocity and roughness of shelterbelt of Salix psammophila was better than that of Artemisia ordosica Krasch. under the same plant spacing. The increasing of Artemisia ordosica Krasch. was seventeen times higher than that of control at the observation point of 1H. The roughness of Salix psammophila at the observation point of 1H was twenty-five times higher than control, and that of Artemisia ordosica Krasch. was seventeen times higher than control.
