| 摘 要： | 以浑善达克沙地东南部多伦县大骆驼场境内的黄柳灌木防风固沙沙障为研究对象,分别研究了行距为5 m和8 m的黄柳沙障对障后风速的影响.结果表明:随着高度的增加,沙障的防风效果逐渐降低,而随着风速的增大,沙障的防风效能却明显增强.行距5 m和行距8 m的沙障分别在第3排和第1排障后风速降低最显著.2种行距沙障障内的风速廓线都遵循一元线性回归.

| Abstract: | The influence of Salix gordejevii sand barriers in different row spacing on wind speed behind them has been studied in Duolun County in Hunshandake Sandy Land.The result shows that: as height rising,wind speed increases.Meanwhile,as wind speed increasing,the windbreak effect is stronger gradually.Salix gordejevii sand barriers have the best windbreak effect behind the third line at row spacing of 5 m and behind the first line at row spacing of 8 m.And their wind profiles follow simple linear regression. |
