Abstract:
Taking Salix psammophila sand barrier laid in 2000 and 2003 as research object，effect of different laying ages on wind characteristics of Salix psammophila sand barrier were studied,to explore the windbreak and sand fixation effectiveness of Salix psammophila sand barrier.The results showed that as the increase of years since the Salix?psammophila sand barrier were set up，the windproof performance in the sample plots increased；the windproof performance in the two quadrates,in which the Salix psammophila sand barrier were up in different year，were maximum at 10 cm，and minimum at 100 cm.Compared with the control group,surface roughness of the sample plots in 2000 and 2003 had been significantly increased to 2.35 times and 3.69 times.The wind profile curve inside of the Salix psammophila sand barrier set up in 2000 changed more obviously than that in 2003.
