- 摘要:
- 以铺设于2000年和2003年沙柳沙障为研究对象，研究了不同铺设年限的沙柳沙障对沙漠地区风速特征的影响，以探讨沙柳沙障的防风固沙效果。结果表明：随着沙柳沙障年限的增加，设障沙柳沙障样地的防风效能增大，2个设障年限样方的防风效能均在10 cm处达到最大，100 cm处最低；设障沙柳沙障使地表粗造度显著地提高，2000年试验样地与2003年试验样地的地表粗糙度值分别是对照粗糙度值的2.35倍和3.69倍；2000年铺设的沙柳沙障内的风速廓线曲线比2003年的变化更显著。
- 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.
