摘要
野外风速测定证实,不同地表覆盖措施均可减少土壤风蚀,其防风降蚀作用由大到小为玉米秸秆平铺覆盖>玉米秸秆堆状覆盖>地膜覆盖。
Field experiments on wind velocity and wind erosion depth show that different surface cover measures can lessen wind erosion. From strong to weak, the effect of controlling wind and shifting sand is： in corn stem paving covering 〉 corn stem piling covering 〉 plastic film covering.
