摘  要:
为定量评价风洞中心风速、植被盖度及交互作用对草原地表风蚀的作用情况,按正交试验设计方案,采用野外风洞原位测试方法,进行了草地土壤风蚀试验。分别用灰色关联度、极差分析、偏最小二乘回归理论,对测试结果进行了分析。结果表明,各因素对输沙率影响主次顺序为:中心风速、植被盖度、二者的交互作用。

摘  要:
In order to quantitative evaluate the wind erosion effect of wind speed in wind tunnel center,vegetation coverage and their interaction,orthogonal experimental design and wind tunnel testing in situ field was adopted.The soil erosion experiment of grassland was completed.Test results were analyzed by using grey correlation,range analysis and partial least-square regression theory.The results showed that the sequence of factors influencing on sediment transport rate from larger to little was the center wind speed of wind tunnel,vegetation coverage,their interaction.
