    摘要:

    為定量評(píng)價(jià)風(fēng)洞中心風(fēng)速,、植被蓋度及交互作用對(duì)草原地表風(fēng)蝕的作用情況，按正交試驗(yàn)設(shè)計(jì)方案,，采用野外風(fēng)洞原位測試方法,，進(jìn)行了草地土壤風(fēng)蝕試驗(yàn)。分別用灰色關(guān)聯(lián)度,、極差分析,、偏最小二乘回歸理論，對(duì)測試結(jié)果進(jìn)行了分析,。結(jié)果表明,，各因素對(duì)輸沙率影響主次順序?yàn)椋褐行娘L(fēng)速、植被蓋度,、二者的交互作用,。

    Abstract:

    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.
